It utilizes the CLIP image encoder and the ArcFace facial recognition module to extract identity features from a reference image, and uses them as a prompt for the diffusion model to enhance the restoration’s performance. The training is conducted in phases using ControlNet and ID encoder modules, and wavelet-based color correction is applied for a final, natural-looking restoration. FaceMe does not require additional training for personalized restoration. Using a variety of reference images, this is a new approach that overcomes limitations of existing face restoration technologies.

To keep your server in sync with user transactions, <a href="https://developer.samsung.com/iap/isn/overview.html">Samsung IAP Instant Server Notification (ISN)</a> sends real-time notifications to your backend server when purchase-related events occur.</p> <p>ISN for Samsung IAP is a method used by Samsung's system to notify your server about user activities related to in-app items and subscriptions. When a change occurs, Samsung sends a notification to your server. A list of all events that trigger a notification is available <a href="https://developer.samsung.com/iap/isn/jwt/payload.html">here</a>.</p> <p>In this article, we will build a Spring Boot server that handles these notifications.</p> <h2 id="Prerequisites">Prerequisites</h2> <p>To implement ISN for Samsung IAP, it is important to focus on the requirements that helps you to most easily implement the process:</p> <ol> <li>Create an IAP public key in the Seller Portal. This key is used to authenticate the notifications you receive and verify that they are from the Samsung IAP ISN system. The steps you need to follow are outlined in the <a href="https://developer.samsung.com/iap/isn/requirements.html#Create-an-IAP-key-in-Seller-Portal">Create an IAP public key in Seller Portal</a> documentation.</li> <li>Create an in-app item in the Seller Portal. Follow the related <a href="https://developer.samsung.com/iap/isn/configure-iap-items-for-isn.html">documentation</a> to create an in-app item.</li> </ol> <h2 id="ISN-Structure">ISN Structure</h2> <p>The ISN for Samsung IAP service sends a notification to the application developer server. The structure of the notification is always a base64-encoded JSON Web Token (JWT) and consists of three parts. The three parts are:</p> <ul> <li>Header</li> <li>Payload</li> <li>Signature</li> </ul> <h3>Header</h3> <p>The JWT uses a JOSE (JavaScript Object Signing and Encryption) header. Similar to the envelope of a letter, the header indicates the type of notification being sent. For additional information, refer to the <a href="https://developer.samsung.com/iap/isn/jwt/header.html">Samsung IAP ISN Header</a> article.</p> <p>Example encoded header:</p> <pre class="language-json"><code class="language-json">eyJ0eXAiOiJKV1QiLCJhbGciOiJSXXXXXXXX </code></pre> <p>Example decoded header:</p> <pre class="language-json"><code class="language-json">{ "alg" : "RS256", "typ" : "JWT" } </code></pre> <h3>Payload</h3> <p>The payload is the actual content of the message, like the letter inside the envelope. This part contains the crucial information you need, like the user’s subscription details, the product they have subscribed to, and the current status of the subscription.</p> <p>More details about the payload check are available in the following <a href="https://developer.samsung.com/iap/isn/jwt/payload.html">documentation</a> and <a href="https://developer.samsung.com/iap/isn/jwt/payload.html#Data-claims">Data claims</a> section.</p> <p>Example encoded payload:</p> <pre class="language-json"><code class="language-json">eyJpc3MiOiJpYXAuc2Ftc3VuZ2FwcHMuY29tIiwic3ViIjoiRVZFTlRfTkFNRSIsImF1ZCI6WyJjb20ucGFja2FnZS5uYW1lIl0sIm5iZiI6MTcxNzIwNCwiaWF0IjoxNzE3MjA0LCJkYXRhIjp7InNlbGxlck5hbWUiOm51bGwsIm NvbnRlbnROYW1lIjoiTWFydGluZSJ9LCJ2ZXJzaW9uIjoXXXXXXXX </code></pre> <p>Example decoded payload:</p> <pre class="language-json"><code class="language-json">{ "iss": "iap.samsungapps.com", "sub": "EVENT_NAME", "aud": ["com.package.name"], "nbf": 1717XXXXXX, "iat": 1717XXXXXX, "data": {..}, "version": "X.0" } </code></pre> <h3>Signature</h3> <p>The signature is the security feature that acts as a digital stamp to prove the message is genuine and hasn’t been tampered with. You can use this signature to verify that the data in the payload is authentic and was created by Samsung.</p> <p>Further information is provided in the signature <a href="https://developer.samsung.com/iap/isn/jwt/signature.html">documentation</a>.</p> <p>Now that we know the structure of the ISN for Samsung IAP, we can configure the server to handle it.</p> <h2 id="Server-Configuration">Server Configuration</h2> <p>According to the ISN for Samsung IAP requirements, you must set up a server to receive the notifications.</p> <p>Below, we create a Spring Boot server. Use your preferred IDE (Integrated Development Environment) or online Spring Initializr to create a Spring Boot server. Follow the steps below to set up your own server.</p> <h3>Step 1: Set Up a Spring Boot Project</h3> <ul> <li>Use the Spring Initializr tool to create a new project.</li> <li>Choose the following dependency: Spring Web</li> <li>Generate and download the project.</li> </ul> <h3>Step 2: Import the Project into IDE</h3> <ul> <li>Open the project in the IDE (IntelliJ, Eclipse, etc.)</li> </ul> <h3>Step 3: Set Up ISN Endpoint</h3> <ol> <li> <p>Create a controller for ISN Notifications in the IDE after importing the Spring Boot project. The controller receives POST requests (Subscription, Refund and Cancel) sent from Samsung’s IAP server.</p> </li> <li> <p>Add necessary dependencies in the <code>build.gradle</code> file:</p> </li> </ol> <pre class="language-java"><code class="language-java">{ implementation 'com.auth0:java-jwt:4.0.0' //For JWT verifier implementation 'org.json:json:20230227' // For JSON parsing } </code></pre> <ol start="3"> <li>Load the public key detailed in the prerequisite section:</li> </ol> <pre class="language-java"><code class="language-java"> private String loadPublicKey(String fileName) throws IOException { ClassPathResource resource = new ClassPathResource(fileName); StringBuilder contentBuilder = new StringBuilder(); try (InputStream inputStream = resource.getInputStream(); BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream))) { String line; while ((line = reader.readLine()) != null) { contentBuilder.append(line).append("\n"); } } return contentBuilder.toString(); } </code></pre> <ol start="4"> <li>Remove headers, footers, and whitespace from the public key and convert it to the RSAPublicKey format.</li> </ol> <pre class="language-java"><code class="language-java"> private RSAPublicKey getRSAPublicKeyFromPEM(String pem) throws Exception { String publicKeyPEM = pem .replace("-----BEGIN PUBLIC KEY-----", "") .replace("-----END PUBLIC KEY-----", "") .replaceAll("\\s", ""); // Remove headers, footers, and whitespace byte[] encoded = Base64.getDecoder().decode(publicKeyPEM); KeyFactory keyFactory = KeyFactory.getInstance("RSA"); X509EncodedKeySpec keySpec = new X509EncodedKeySpec(encoded); return (RSAPublicKey) keyFactory.generatePublic(keySpec); } </code></pre> <ol start="5"> <li>Create a JWT verifier with RSAPublicKey and, finally, verify the JWT. If the verification is successful, decode the JWT to retrieve the decoded JSON payload. The decoded payload contains the message of the notification.</li> </ol> <pre class="language-java"><code class="language-java"> private void verifyToken(String token, RSAPublicKey publicKey) { try { // Create JWT verifier with RSA public key Algorithm algorithm = Algorithm.RSA256(publicKey, null); // Verify the JWT token JWTVerifier verifier = JWT.require(algorithm) .withIssuer("iap.samsungapps.com") .build(); DecodedJWT jwt = verifier.verify(token); // Decode the JWT token String payloadJson = new String(Base64.getDecoder().decode(jwt.getPayload())); JSONObject jsonObject = new JSONObject(payloadJson); //Print decoded JSON payload System.out.println("Payload as JSON: " + jsonObject.toString(4)); } catch (JWTVerificationException e) { System.out.println("Invalid token: " + e.getMessage()); } } </code></pre> <p>In this <a href="/SDP/file/17953388-cb24-4a53-a027-c6c14f3b14d1">sample project</a>, we have only printed the payload data to the console. You can use this according to your requirements.</p> <h3>Step 4: Deploy the Server</h3> <p>The server needs a publicly accessible URL to receive ISN notifications. In our project, we have used CodeSandbox to get the publicly accessible URL for the server. Once you deploy the project on CodeSandbox, you will get a publicly accessible URL that looks like this: <code>https://abcde-8080.csb.app/iap/isn</code>.</p> <h2 id="Testing-with-Seller-Portal">Testing with Seller Portal</h2> <p>Test your server with Samsung Galaxy Store Seller Portal:</p> <ol> <li> <p>Set the CodeSandbox URL as the ISN URL in Seller Portal.</p> <ul> <li>Go to the In-App Purchase section and create items with the required details.</li> <li>In the "ISN URL" field, set the publicly accessible server URL.</li> </ul> </li> <li> <p>After setting the URL, click the <code>Test</code> button. A notification will be sent to the specified server immediately. You will also receive a notification on the server that you just deployed in the CodeSandbox.</p> </li> </ol> <div class="flex-container py-3"><div> </div> <div> <div class="doc-img-content"> <div class="doc-img-holder"> <img src="https://d3unf4s5rp9dfh.cloudfront.net/SDP_blog/2025-03-11-01-01.png" alt="undefined" style="max-width: 100%; height:300px;" class="img-fluid"> </div> </div> </div> <div> </div> </div> <div class="flex-container py-3"><div> </div> <div> Figure 1: Testing with Seller Portal </div> <div> </div> </div> <h2 id="Testing-with-a-Sample-Application">Testing with a Sample Application</h2> <p>Now it is time to test the ISN for Samsung IAP from the user application. Further details are provided in the <a href="https://developer.samsung.com/sdp/blog/en/2024/12/10/integrate-the-samsung-in-app-purchase-orders-api-with-your-application">Integrate the Samsung In-App Purchase Orders API with Your Application</a> article. <a href="/SDP/file/c16843d3-b993-40a7-856f-2630e54679b5">Download the sample application</a> from this blog and then follow the instructions until you reach the "Implementation of Item Subscription" section.</p> <p>In the sample application, after clicking the "Buy" button, <code>startPayment()</code> is called. The <code>onPayment()</code> callback returns an indication of whether the purchase succeeds or fails. If the purchase is successful, the IAP server sends a notification to your server.</p> <pre class="language-java"><code class="language-java"> iapHelper.startPayment(itemId, String.valueOf(1), new OnPaymentListener() { @Override public void onPayment(@NonNull ErrorVo errorVo, @Nullable PurchaseVo purchaseVo) { if (purchaseVo != null) { Log.d("purchaseId" , purchaseVo.getPurchaseId().toString()); // Purchase successfull }else { Log.d("purchaseError" , errorVo.toString()); } } }); </code></pre> <h3>Example Response</h3> <p>After successfully purchasing an item, a JSON response is returned.

For subscription services, the revenue share model will be 85% / 15%.</p> <p>For all developers and publishers who are currently publishing an app on Galaxy Store and obtained certification via the Galaxy Store Seller Portal, no action is required to start benefiting from this higher revenue share. Unless you have a custom agreement, Samsung will automatically apply the new revenue share terms on May 15, 2025 (GMT+0).

To maximize MIMO performance, base stations (BS) require downlink Channel State Information (CSI) feedback from user equipment (UE). However, limited uplink channel resources can lead to overload issues. Therefore, maintaining CSI feedback accuracy while minimizing overhead is a critical challenge.<br> <br> To address this, Samsung Research proposes an AI-based One-Sided CSI Feedback method. This approach applies a deep learning model solely at the base station, reducing feedback overhead and protecting data privacy. This solution enables operation without collaboration among vendors.

You can create a watch face using weather data as art.</p> <p>This article introduces the following weather features which enhance watch face design:</p> <ol> <li>Weather forecast</li> <li>The last time the weather was updated in ICU format</li> <li>Weather tags</li> </ol> <p>You can follow the examples in this article by downloading the sample project from <a href="/SDP/file/e3948779-d93e-4441-b7d8-adfa54b89df9">here</a>.</p> <h2 id="Forecast-for-the-next-few-hours-and-days">Forecast for the next few hours and days</h2> <p>Weather information becomes more valuable when presented in a way that is easy to read at a glance. Using weather tags, WFS enables you to easily incorporate forecasts for the coming hours and days.</p> <h3>Hourly forecast</h3> <p>The <code>forecastHours(index, text)</code> tag can be used to show hourly weather updates. One of the two pieces of information that the forecastHours tag collects is an index that takes a number starting at 1 for the following hour. Thus, by setting the index, you can set the data for the next few hours.</p> <p>The text part uses five distinct weather tags:<br> • Temperature<br> • Time of day<br> • Weather condition<br> • Weather condition name<br> • Weather data available</p> <p>Use the forecastHours tag with the weather condition, time, and temperature to offer users a short-term forecast of what to expect throughout the day. Tiny weather icons (like Sunny: ☀️, Rainy: 🌧️, and Snow: ❄️) can be used as bitmaps portraying the current weather conditions and the corresponding temperatures.</p> <h3>Forecast hours for icon</h3> <p>You can set the weather icon for the upcoming hour by following these steps:</p> <ol> <li>Create a text component.</li> <li>Use this forecast tag on the text: <strong>forecastHours (1, "COND")</strong></li> <li>Choose the <strong>Bitmap Font</strong> to use icons for the forecastHours ().</li> <li>Select images for the appropriate weather conditions.</li> </ol> <div class="alert alert-v2 alert-info" role="alert"><strong>Note</strong><span>You need to create the icons, using any design tool, for your project.</span></div> <br> 5.

You may display the temperature (positive or negative) for the upcoming hour and the temperature unit in degrees by following these steps:</p> <ol> <li>Consider a text element.</li> <li>To display the temperature in degrees, use <strong>forecastHours(1,"TEM")°</strong></li> <li>Choose the temperature unit <strong>(([WTHR_TEM_UNIT] == 1)? "C": "F")</strong><br> The full tag expression looks like this:<br> <code>(forecastHours(1, "TEM"))°(([WTHR_TEM_UNIT] == 1)? "C": "F"))</code><br> To display the weather forecast for the next hour, just change the index value to 2.</li> </ol> <h3>Availability of weather data</h3> <p>For every forecast tag, you need to check if the data is available with this tag: <strong>(forecastHours(X, "IS_AVAIL"))</strong>.<br> In the sample project, for every forecast group, the corresponding weather tag is used for checking its availability. The following tag expression is used for the next hour’s forecast:<br> <code>((forecastHours(1, "IS_AVAIL")) - 1) * 100</code></p> <div class="flex-container py-3"><div> <div class="doc-img-content"> <div class="doc-img-holder"> <img src="https://d3unf4s5rp9dfh.cloudfront.net/SDP_blog/ImagePlaceholder_WhiteBlock_1x1.jpg" alt="undefined" class="img-fluid" style="max-width: 100%;"> </div> </div> </div> <div> <div class="doc-img-content"> <div class="doc-img-holder"> <img src="https://d3unf4s5rp9dfh.cloudfront.net/SDP_blog/2025-01-20-01-03.png" alt="undefined" class="img-fluid" style="max-width: 100%;"> </div> </div> </div> <div> <div class="doc-img-content"> <div class="doc-img-holder"> <img src="https://d3unf4s5rp9dfh.cloudfront.net/SDP_blog/ImagePlaceholder_WhiteBlock_1x1.jpg" alt="undefined" class="img-fluid" style="max-width: 100%;"> </div> </div> </div> </div> <div class="flex-container py-3"><div> <div class="doc-img-content"> <div class="doc-img-holder"> <img src="https://d3unf4s5rp9dfh.cloudfront.net/SDP_blog/ImagePlaceholder_WhiteBlock_50x1.jpg" alt="undefined" style="max-width: 100%; height:0px;" class="img-fluid"> </div> </div> </div> <div> <p><em>Figure 3: Tag expression for checking availability of weather data</em></p> </div> <div> <div class="doc-img-content"> <div class="doc-img-holder"> <img src="https://d3unf4s5rp9dfh.cloudfront.net/SDP_blog/ImagePlaceholder_WhiteBlock_1x1.jpg" alt="undefined" style="max-width: 100%; height:0px;" class="img-fluid"> </div> </div> </div> </div> <h3>Daily forecast</h3> <p>You can incorporate daily weather forecasts into watch face designs using the <code>forecastDays()</code> tag. Customized indices (for example, 1 for tomorrow) make it simple to portray multi-day weather trends. WFS lets you show the weather conditions for a certain day, including high and low temperatures using <strong>forecastDays(index, "TEM_HIGH")</strong> for highest temperature and <strong>forecastDays(index, "TEM_LOW")</strong> for lowest temperature.</p> <p>The later parts of the sample project show the weather predictions for tomorrow.</p> <p>WFS uses the <strong>forecastDays(1,"TEM_HIGH")</strong> tag to show the temperature for the following day’s high and <strong>forecastDays(1,"TEM_LOW")</strong> tag for the next day’s low.</p> <p>For the high and low temperatures tomorrow, use the following tag expression:<br> <code>(forecastDays(1,"TEM_HIGH"))° ~ (forecastDays(1,"TEM_LOW"))°(([WTHR_TEM_UNIT] == 1)? "C": "F")</code></p> <p>You can apply a similar tag expression for the forecast for the days after tomorrow by changing the index value.</p> <h3>Last weather update (ICU format)</h3> <p>This watch face example incorporates the most current update time to reassure customers that the weather information is recent. Weather data should be updated often to remain accurate.</p> <p>WFS offers the most recent weather update in the ICU format. To add the most recent weather update time in ICU format, follow these steps:</p> <ol> <li>From the component list, get the <strong>ICU date and time.</strong></li> </ol> <div class="flex-container py-3"><div> <div class="doc-img-content"> <div class="doc-img-holder"> <img src="https://d3unf4s5rp9dfh.cloudfront.net/SDP_blog/ImagePlaceholder_WhiteBlock_1x1.jpg" alt="undefined" class="img-fluid" style="max-width: 100%;"> </div> </div> </div> <div> <div class="doc-img-content"> <div class="doc-img-holder"> <img src="https://d3unf4s5rp9dfh.cloudfront.net/SDP_blog/2025-01-20-01-04.png" alt="undefined" class="img-fluid" style="max-width: 100%;"> </div> </div> </div> <div> <div class="doc-img-content"> <div class="doc-img-holder"> <img src="https://d3unf4s5rp9dfh.cloudfront.net/SDP_blog/ImagePlaceholder_WhiteBlock_1x1.jpg" alt="undefined" class="img-fluid" style="max-width: 100%;"> </div> </div> </div> </div> <div class="flex-container py-3"><div> <div class="doc-img-content"> <div class="doc-img-holder"> <img src="https://d3unf4s5rp9dfh.cloudfront.net/SDP_blog/ImagePlaceholder_WhiteBlock_50x1.jpg" alt="undefined" style="max-width: 100%; height:0px;" class="img-fluid"> </div> </div> </div> <div> <p><em>Figure 4: ICU date and time</em></p> </div> <div> <div class="doc-img-content"> <div class="doc-img-holder"> <img src="https://d3unf4s5rp9dfh.cloudfront.net/SDP_blog/ImagePlaceholder_WhiteBlock_1x1.jpg" alt="undefined" style="max-width: 100%; height:0px;" class="img-fluid"> </div> </div> </div> </div> <ol start="2"> <li>To customize the ICU date and time, select the <strong>PROPERTIES</strong> tab.</li> <li>Choose the ICU Format as HH: MM from the <strong>DATE AND TIME</strong> section.</li> <li>Set the <strong>Local Calendar</strong> to <strong>Gregorian</strong> and the <strong>Time Zone</strong> to <strong>Sync with Device.</strong></li> <li>Select <strong>Last Updated Time (Weather)</strong> as the <strong>Time Source.</strong></li> </ol> <div class="flex-container py-3"><div> <div class="doc-img-content"> <div class="doc-img-holder"> <img src="https://d3unf4s5rp9dfh.cloudfront.net/SDP_blog/ImagePlaceholder_WhiteBlock_1x1.jpg" alt="undefined" class="img-fluid" style="max-width: 100%;"> </div> </div> </div> <div> <div class="doc-img-content"> <div class="doc-img-holder"> <img src="https://d3unf4s5rp9dfh.cloudfront.net/SDP_blog/2025-01-20-01-05.png" alt="undefined" class="img-fluid" style="max-width: 100%;"> </div> </div> </div> <div> <div class="doc-img-content"> <div class="doc-img-holder"> <img src="https://d3unf4s5rp9dfh.cloudfront.net/SDP_blog/ImagePlaceholder_WhiteBlock_1x1.jpg" alt="undefined" class="img-fluid" style="max-width: 100%;"> </div> </div> </div> </div> <div class="flex-container py-3"><div> <div class="doc-img-content"> <div class="doc-img-holder"> <img src="https://d3unf4s5rp9dfh.cloudfront.net/SDP_blog/ImagePlaceholder_WhiteBlock_50x1.jpg" alt="undefined" style="max-width: 100%; height:0px;" class="img-fluid"> </div> </div> </div> <div> <p><em>Figure 5: Date and Time</em></p> </div> <div> <div class="doc-img-content"> <div class="doc-img-holder"> <img src="https://d3unf4s5rp9dfh.cloudfront.net/SDP_blog/ImagePlaceholder_WhiteBlock_1x1.jpg" alt="undefined" style="max-width: 100%; height:0px;" class="img-fluid"> </div> </div> </div> </div> <h3>Other weather tags</h3> <h4>Current weather condition for icon</h4> <p>You can use the bitmap font for the current weather condition since it is already prepared for forecastHours(). Use the <strong>[WTHR_COND]</strong> tag, which provides the current weather, and choose bitmap as the font setting.</p> <h4>Current temperature</h4> <p>Use the <strong>[WTHR_TEM]</strong> tag to show the current temperature. The current temperature is obtained with the following tag expression, which also sets the temperature unit:<br> <code>[WTHR_TEM]°(([WTHR_TEM_UNIT] == 1)? "C": "F")</code></p> <h4>Today’s highest and lowest temperatures</h4> <p>You can display the highest and lowest temperatures of the day by using the tags <strong>[WTHR_DAY_TEM_HIGH])</strong> for the highest temperature and <strong>[WTHR_DAY_TEM_LOW]</strong> for the lowest temperature. The highest and lowest temperatures for today are listed below, based on the forecastDays() tag expression for the highest and lowest temperatures for the following day:<br> <code>([WTHR_DAY_TEM_HIGH])° ~ ([WTHR_DAY_TEM_LOW])°(([WTHR_TEM_UNIT] == 1)? "C": "F")</code></p> <h3>Summary</h3> <p>Smartwatches offering weather forecasts are useful and engaging. With WFS, designers can use advanced tags like forecastDays(), forecastHours(), and last update time to deliver real-time weather updates, daily forecasts, and information such as high and low temperatures. Because they provide information at a glance, smartwatch faces are practical and attractive.</p> <p>If you have questions or need help with the information presented in this article, you can share your queries on the <a href="https://forum.developer.samsung.com/">Samsung Developers Forum</a>.

However, single models with different architectures or random initialization states exhibit prediction deviations from ground truths, resulting in sub-optimal restoration results. Ensemble learning has been applied to image restoration to address this issue, but most ensemble methods in image restoration require ensembles in the training stage. The ensemble strategy must be determined while training multiple models, so it sacrifices flexibility in changing models and the convenience of plug-and-play usage.<br> <br> This article introduces EnsIR, an image restoration ensemble algorithm based on Gaussian mixture models (GMMs). This method formulates the ensemble problem, and ensemble weights are efficiently learned via the expectation maximization (EM) algorithm, which is stored in a lookup table (LUT) to be utilized in the subsequent inference stage. This algorithm demonstrates better performance than regression-based ensemble methods and commonly used averaging strategies. It can be applied to various image restoration tasks.

Blind Face Restoration (BFR) is a challenging task that aims to restore low-quality face images and videos that suffer from unknown degradation. Existing BFR methods have used facial priors such as reference prior, geometry prior, and generative prior in the network structure to perform restoration. However, they mostly focused on blind face image restoration (BFIR) with still images and have not been fully utilized for video restoration. <br> <br> In this study, we present a new method called Stable Blind Face Video Restoration (StableBFVR). With StableBFVR, we have introduced temporal layers in the Stable Diffusion model that can preserve temporal consistency. The temporal layers are designed using two core technologies: Shift-Resblock that handles long-term information, and Nearby-Frame Attention that utilizes short-term information. Find out more about StableBFVR and how it performs better than existing methods at the Samsung Research blog.</span><br> <br> <span style="font-size:14px;"><b><a alias="더 알아보기" conversion="false" data-linkto="https://" href="https://research.samsung.com/blog/Blind-Face-Video-Restoration-with-Temporal-Consistent-Generative-Prior-and-Degradation-Aware-Prompt" style="color:#0081FF;text-decoration:underline;" title="더 알아보기">Learn more</a></b></span></div></td></tr></tbody></table></td></tr></tbody></table></td></tr></tbody></table></td></tr></tbody></table><table cellpadding="0" cellspacing="0" width="100%" role="presentation" style="background-color: transparent; min-width: 100%; border-top: 0px; border-right: 0px; border-bottom: 1px solid #C9C9C9; border-left: 0px; " class="stylingblock-content-wrapper"><tbody><tr style="background-color: transparent;"><td style="padding: 20px 10px 0px; " class="stylingblock-content-wrapper camarker-inner"><table cellspacing="0" cellpadding="0" role="presentation" style="width: 100%;"><tbody><tr style="background-color: transparent;"><td><table cellspacing="0" cellpadding="0" role="presentation" style="width: 100%;"><tbody><tr style="background-color: transparent;"><td valign="top" class="responsive-td" style="width: 100%;"><table cellpadding="0" cellspacing="0" width="100%" role="presentation" style="text-align: left; min-width: 100%; " class="stylingblock-content-wrapper"><tbody><tr style="background-color: transparent;"><td class="stylingblock-content-wrapper camarker-inner" align="left"><table width="100%" cellspacing="0" cellpadding="0" role="presentation"><tbody><tr style="background-color: transparent;"><td align="center"><a href="https://research.samsung.com/blog/SAMSEMO-New-dataset-for-multilingual-and-multimodal-emotion-recognition" title="" alias="" conversion="false" data-linkto="https://"><img data-assetid="91809" src="https://image.email.samsungdevelopers.com/lib/fe3611747364047f751577/m/1/b0b76b34-0400-483b-9c51-be860698e9e4.png" alt="" width="500" style="max-width: 100%; display: block; text-align: center; padding: 0px; height: auto; width: 100%;"></a></td></tr></tbody></table></td></tr></tbody></table><table cellpadding="0" cellspacing="0" width="100%" role="presentation" style="text-align: left; background-color: transparent; min-width: 100%; " class="stylingblock-content-wrapper"><tbody><tr style="background-color: transparent;"><td style="padding: 10px 5px 25px; " class="stylingblock-content-wrapper camarker-inner" align="left"><h3 style="line-height: 115%;"> <strong>SAMSEMO: New Dataset for Multilingual and Multimodal Emotion Recognition</strong></h3><div style="line-height: 115%;"> <span style="font-size:14px;">Multimodal emotion recognition, recently gaining popularity, is a study area that analyzes a variety of communication signals including images, voices, and text in a multilateral way. However, the list of large-scale multimodal datasets is very short and the available datasets have various limitations. Hence, Samsung R&D Institute Poland presents a new dataset for multimodal and multilingual emotion recognition: Samsung Multimodal and Multilingual Dataset for Emotion Recognition (SAESEMO).<br> <br> SAESEMO contains over 23,000 video scenes in 5 languages (Korean, English, German, Spanish, and Polish) collected from diverse sources. All video scenes are accompanied with rich metadata and emotion connotations collected manually. The study also analyzes balance and energy of audio features for the most important emotion classes and compares them with CMU-MOSEI data. Moreover, it carries out multimodal experiments for emotion recognition with SAESEMO and shows how to use a multilingual model to improve the detection of imbalanced classes.

FWA users can consume 20 to 30 times more data compared to regular mobile users, placing a significant strain on the network.<br> <br> Most existing FWA systems operate in Frequency Range 1 (FR1), meaning frequencies of 6 GHz or below. However, using Frequency Range 2 (FR2), which uses frequencies ranging from 24.25 to 71 GHz, can help improve FWS coverage and data demands. This article discusses key technology innovations that enable improved coverage and capacity for FR2-based FWA systems of 5G and 6G.

This tutorial demonstrates how you can perform server interactions with the Samsung Wallet server and retrieve information such as the card states on a user’s device.</p> <p>If you are a Samsung Wallet partner who is offering Samsung Wallet cards to your users, you might also want to know how you can track a provided wallet card’s status on a user’s device. Follow along in this tutorial to learn how you can utilize the Send Card State API and retrieve this information to your own server. All code examples used in this tutorial can be found within the sample code provided at the end of this tutorial for further reference.</p> <h2 id="Card-states-and-the-Send-Card-State-API">Card states and the Send Card State API</h2> <p>The Samsung Wallet card’s status on a user’s device is represented by various states, such as ADDED, UPDATED, or DELETED.</p> <p>Whenever the card state of a card changes on a user’s device, Samsung Wallet server sends a notification to the configured partner server informing about the change. This API provided by Samsung is called the Send Card State API.</p> <div class="flex-container py-3"><div> </div> <div> <div class="doc-img-content"> <div class="doc-img-holder"> <img src="https://d3unf4s5rp9dfh.cloudfront.net/SDP_blog/2024-11-19-01.png" alt="undefined" style="max-width: 100%; height:500px;" class="img-fluid"> </div> </div> </div> <div> </div> </div> <div class="flex-container py-3"><div> </div> <div> Figure 1: Samsung Wallet Card state changes </div> <div> </div> </div> <p>Samsung provides the Send Card State API as a means of server-to-server communication between the Samsung server and the partner’s server and to let the partner know about the card state of their issued cards on user’s devices. With this API, partners can track the state of a wallet card on a user’s Samsung Galaxy device.</p> <h2 id="Prerequisites">Prerequisites</h2> <p>Before you can test the Send Card State API, you need to:</p> <ol> <li>Complete the <a href="https://developer.samsung.com/wallet/api_new/getting/guide.html">Samsung Wallet onboarding process</a>.</li> <li><a href="https://developer.samsung.com/wallet/api_new/getting/templates.html#Create-Wallet-Cards-(Draft-status)">Create a Samsung Wallet card template</a>.</li> <li>Launch the wallet card template and have it in VERIFYING or ACTIVE status so that the card can be added to a user’s device.</li> <li>Have an existing server to receive the notifications. You can use CodeSandbox or a similar online hosting service for testing.</li> <li>Configure your firewall (if you use any) to accept incoming connections from the Samsung Wallet server (34.200.172.231 and 13.209.93.60).</li> </ol> <p>When you have completed all the prerequisites, proceed to the next step to configure your wallet card template to send requests to your server.</p> <h2 id="Configure-the-Wallet-card-template-for-the-Send-Card-State-API">Configure the Wallet card template for the Send Card State API</h2> <p>To receive the Send Card State notifications on your server, you need to set your server’s URL in the desired Samsung Wallet card’s options:</p> <ol> <li>Go to the <a href="https://partner.walletsvc.samsung.com/">Wallet Partners Portal</a>.</li> <li>From the Wallet Cards dropdown, select “Manage Wallet Card.”</li> <li>Click the name of the wallet card.</li> <li>Click “Edit” and then scroll down to the “Partner Send card state” section to modify the Partner server URL.</li> <li>Click “Save” to set the partner server URL for the card.</li> </ol> <div class="flex-container py-3"><div> </div> <div> <div class="doc-img-content"> <div class="doc-img-holder"> <img src="https://d3unf4s5rp9dfh.cloudfront.net/SDP_blog/2024-11-19-02.png" alt="undefined" style="max-width: 100%; height:150px;" class="img-fluid"> </div> </div> </div> <div> </div> </div> <div class="flex-container py-3"><div> </div> <div> Figure 2: Partner Send card state URL input field </div> <div> </div> </div> <p>Now, whenever a user adds or deletes an issued Samsung Wallet card to their device, the Samsung Wallet server automatically sends a POST notification to the Partner server URL set in the Wallet Partners Portal. Next you need to learn about the specification of the request so that you can handle it from the server.</p> <h2 id="Send-Card-State-API-specification-and-format">Send Card State API specification and format</h2> <p>For a complete description of the Send Card State API specification, see <a href="/wallet/api/server-interaction.html#Send-Card-State">Samsung Wallet documentation</a>.</p> <h3>Request method</h3> <p>The Send Card State API uses a <strong>POST</strong> method to send a request to the server. The API path for the request is fixed and uses the partner server URL that you defined in section “Configure the Wallet card template for the Send Card State API.”</p> <h3>API path and URL parameters</h3> <p>The API path at the very end of the "Partner Send card state" section is the path where the Samsung server sends the Send card state POST request. So the complete API path URL is: <code>{Partner server URL}/cards/{cardId}/{refId}?cc2={cc2}&event={event}</code>.</p> <p>Here, <code>cardId</code> is the Card ID of the wallet card template and <code>refId</code> is the reference ID field of the issued card data, which is a unique identifier. The <code>cc2</code> query parameter is the 2-letter country code (<a href="https://www.iso.org/iso-3166-country-codes.html">ISO 3166-1 alpha-2</a>) and <code>event</code> is the card state event (ADDED, DELETED, or UPDATED) occurring in the user’s device.</p> <p>Consider the following example card configuration:</p> <ul> <li>Partner server URL: <strong>https://partner.server.url</strong></li> <li>Card id: <strong>123</strong></li> <li>Ref id for the issued card: <strong>abc</strong></li> <li>Country code: <strong>US</strong></li> </ul> <p>In this configuration, whenever the user adds the card to their Samsung Wallet application, the Samsung Wallet server sends a Send card state notification to the following URL:<br> <code>https://partner.server.url/cards/123/abc?cc2=US&event=ADDED</code>.</p> <p>Similarly, if <strong>a user from the United Kingdom</strong> <strong>deletes</strong> a card with the <code>refId</code> <strong>xyz</strong>, the POST request is sent to <code>https://partner.server.url/cards/123/xyz?cc2=GB&event=DELETED</code>.</p> <p>Therefore, you can know if a card was added or removed from the user’s device directly from the query parameters.</p> <h3>POST request body</h3> <p>The POST request body does not contain any information regarding the card state. Rather it just provides a callback URL that you can use if you want to send an update notification for the card.</p> <pre class="language-json"><code class="language-json">{ "callback": "https://us-tsapi.walletsvc.samsung.com" } </code></pre> <h3>POST request header</h3> <p>The POST request header contains all the required information for ensuring the authenticity of the request. It contains a request ID with the name “x-request-id” and a JWT bearer token credential for authentication with the name “Authorization” in the header.</p> <p>The Samsung Wallet server uses a bearer authorization token to ensure the authenticity of the requests being sent to the partner server. For details of the security factors, see <a href="/wallet/api/security.html#Authorization-Token">Authorization Token</a>.</p> <p>The bearer token is encoded in base64 following the JWT specification. It has three parts: JWS Header containing authentication related information, JWS Payload containing the API path, method, and refID, and JWS Signature, which validates that the bearer token is signed by the Samsung server.</p> <p><strong>JWS Header format:</strong></p> <pre class="language-json"><code class="language-json">{ "cty": "AUTH", // Always “AUTH” "ver": "3", // Can also be “2” for legacy card data token "partnerId": "4048012345678938963", // Your partner ID "utc": 1728995805104, // Time of signing in milliseconds "alg": "RS256", "certificateId": "A123" // Only provided for token version 3 } </code></pre> <p><strong>JWS Payload format:</strong></p> <pre class="language-json"><code class="language-json">{ "API": { "path": "/cards/3h844qgbhil00/2e19cd17-1b3e-4a3a-b904?cc2=GB&event=ADDED", "method": "POST" }, "refId": "2e19cd17-1b3e-4a3a-b904-f30dc91ac264" } </code></pre> <p>Finally, the bearer token contains a signature to verify the token. This is signed using the Samsung Private Key and can be validated using the Public Key provided by Samsung Wallet during the onboarding process.</p> <p>After receiving any request from the Samsung Wallet server, your server should send back an HTTP status code as a response. Samsung Server expects one of the following codes as a response:</p> <ul> <li>200 OK</li> <li>401 Unauthorized</li> <li>500 Internal Server Error</li> <li>503 Service Unavailable</li> </ul> <p>This is the complete specification of the Send Card State API that you need to be aware of before you implement the server.</p> <p>Next, you need to configure your server to accept the POST request in the specified format.</p> <h2 id="Configure-the-Spring-server-to-receive-the-POST-request">Configure the Spring server to receive the POST request</h2> <p>To receive and interpret the Send Card State POST notifications sent by the Samsung Wallet server, you need to configure a partner server and host the server at the URL you specified earlier.</p> <p>To receive the POST requests, this tutorial extends an existing server created using the Spring Boot framework. If you want to know how the Spring server is configured, check out the “Generate signed Wallet card data” section in the <a href="/sdp/blog/en/2024/05/14/implementing-add-to-wallet-in-an-android-application#Generate-signed-Wallet-card-data">Implementing "Add to Wallet" in an Android Application</a> tutorial. This CData generation server is used as the base server application for this tutorial, so the dependencies are the same as well. Now you can start implementing the tutorial.</p> <h3>Create a controller class to intercept the POST request</h3> <p>Samsung Wallet always sends the Send card state POST notification to the fixed API path URL: <code>{Partner server URL}/cards/{cardId}/{refId}</code>.</p> <ol> <li class="theme-dark"> Create a new controller class in your Spring server to intercept any POST request that is sent to this API path. <pre class="language-kotlin"><code class="language-kotlin">@RestController @RequestMapping("/cards") class CardStateController { @PostMapping(path = ["/{cardId}/{refId}"]) fun handleCardState(@PathVariable cardId: String, @PathVariable refId: String): HttpStatusCode { // Implement your logic here to process the card state. println("Received card state notification for card ID $cardId and reference ID $refId.") return HttpStatus.OK } } </code></pre> </li> <li>Run the server and then add or delete a card from your Samsung Wallet. <p>If the partner server URL was set correctly in section “Configure the Wallet card template for the Send Card State API,” your server should receive a POST request from the Samsung server and print the following message to the console: “Received card state notification.” </p></li><p></p> </ol> <h3>Update the controller class to receive the query parameters</h3> <ol> <li>Handle the query parameters from the request by adding the following parameters as the function’s parameters: <code>@RequestParam("cc2") cc2: String</code>, <code>@RequestParam("event") event: String</code></li> <li>Receive and print the request body using the <code>@RequestBody body: String</code> parameter.</li> </ol> <p>The function should now look like this:</p> <pre class="language-kotlin"><code class="language-kotlin">@PostMapping(path = ["/{cardId}/{refId}"], params = ["cc2", "event"]) fun handleCardState(@PathVariable cardId: String, @PathVariable refId: String, @RequestParam("cc2") cc2: String, @RequestParam("event") event: String, @RequestBody body: String): HttpStatusCode { // Implement your logic here to process the card state. println("Country code: $cc2") println("Wallet Card State Event: $event") println("Request body: $body") return HttpStatus.OK } </code></pre> <p>Now whenever the Samsung server sends a request to the server, it prints the device’s country code and the wallet card’s state event on the device.</p> <h2 id="Verify-the-POST-request">Verify the POST request</h2> <p>This is the final and the most important step of this tutorial. Before accepting any incoming POST request, you should always validate the request by following the API specification mentioned earlier in the tutorial.</p> <p>The security procedures can include but are not limited to:</p> <ul> <li>Matching your <code>PartnerID</code> with the received <strong>partnerId</strong> custom parameter.</li> <li>Checking the token version with the <strong>ver</strong> custom parameter. For token version <strong>3</strong>, match your <code>CertificateID</code> using the <strong>certificateId</strong> custom parameter.</li> <li>Checking the time of signing using the <strong>utc</strong> custom parameter.</li> <li>Matching the other JWS Header parameters with the values mentioned in the specification.</li> <li>Matching the Path from the JWS Payload with the received URL.</li> <li>Verifying the JWT.</li> </ul> <p>This section shows how you can implement each of these one by one.</p> <p>First, parse the authentication token and read the header.</p> <pre class="language-kotlin"><code class="language-kotlin">val signedJWT : SignedJWT = SignedJWT.parse(authToken) val jwsHeader : JWSHeader = signedJWT.header </code></pre> <p>Match <code>PartnerId</code> and JWS Header parameters:</p> <pre class="language-kotlin"><code class="language-kotlin">val ownPartnerId = "4048012345678938963" // Your partner ID from Samsung Wallet Partner Portal val receivedPartnerId = jwsHeader.customParams["partnerId"] val cType = jwsHeader.contentType val alg = jwsHeader.algorithm.name // Check if the JWS header parameters match the expected values if (cType == "AUTH" && alg == "RS256" && receivedPartnerId == ownPartnerId ) { println("JWS Header parameters matched") // Proceed with further verification } </code></pre> <p>Check the token version and match <code>CertificateId</code>:</p> <pre class="language-kotlin"><code class="language-kotlin">val ver = jwsHeader.customParams["ver"] val ownCertificateId = "A123" // Your certificate ID from Samsung Wallet Partner Portal val receivedCertificateId = jwsHeader.customParams["certificateId"]?: "" // If partner uses token version 3 in the JWS header of the CDATA, // Then Samsung server also returns version 3 response along with the certificate ID if(ver == "3" && receivedCertificateId == ownCertificateId){ println("JWS Header certificate ID matched") // Proceed with further verification } </code></pre> <p>Check if the token was generated recently:</p> <pre class="language-kotlin"><code class="language-kotlin">// Check if the timestamp is within acceptable range val utc = jwsHeader.customParams["utc"] as Long val timeDelta = System.currentTimeMillis() - utc println("Time Delta: $timeDelta") if (timeDelta < 600000L) { println("UTC Timestamp is within last 1 minute.

For instructions, refer to the CData generation server sample code at <a href="/sdp/blog/en/2024/05/14/implementing-add-to-wallet-in-an-android-application#Resources">Implementing "Add to Wallet" in an Android Application</a>.</li> <li>Build an <a href="https://www.javadoc.io/doc/com.nimbusds/nimbus-jose-jwt/9.3/com/nimbusds/jose/jwk/RSAKey.html">RSAKey</a> object using the extracted public key.</li> <li>Create an <a href="https://www.javadoc.io/doc/com.nimbusds/nimbus-jose-jwt/9.3/com/nimbusds/jose/crypto/RSASSAVerifier.html">RSASSAVerifier</a> object with the RSAKey to verify the token.</li> <li>Verify the token using the verifier.</li> </ol> <pre class="language-kotlin"><code class="language-kotlin">// Verify the signature of the JWT token using the public key provided by Samsung Wallet. val samsungPublicKey = readCertificate(getStringFromFile("sample/securities/Samsung.crt")) val rsaKey = RSAKey.Builder(samsungPublicKey as RSAPublicKey).build() val verifier: RSASSAVerifier = RSASSAVerifier(rsaKey) if(signedJWT.verify(verifier)){ println("Verification successful") // Implement your logic here to process the card state notification. // For example, you can update the card status in your database or trigger a notification to the user. // In this example, we simply return a 200 OK response indicating that the notification was successfully processed. return HttpStatus.OK } else { println("Verification Failed") // Return an appropriate HTTP status code indicating that the notification could not be verified. return HttpStatus.UNAUTHORIZED } </code></pre> <p>Now the complete implementation of the <code>Controller</code> class to receive and verify the Send card state request is complete. Once a Send card state request is completely verified, you can accept the request as a valid card state update and make any changes as required. For example, you can update the card status information in your own database or trigger a notification to the user.</p> <h2 id="Summary">Summary</h2> <p>By completing this tutorial, you are now able to receive card state updates from the Samsung Wallet server using the Send Card State API and validate them. In a future tutorial, we will discuss how you can expand the server interaction functionality even further and how you can update Samsung Wallet card information on user devices through the Get Card Data API.</p> <p>If you want to discuss or ask questions about this tutorial, you can share your thoughts or queries on the <a href="https://forum.developer.samsung.com/">Samsung Developers Forum</a> or contact us directly for any implementation-related issues through the <a href="https://developer.samsung.com/dev-support">Samsung Developer Support Portal</a>.
