Over the past few years, we've utilized innovations in cryptographic research to keep your personal information private by design and secure by default. As part of this, we launched <a href="https://security.googleblog.com/2019/02/protect-your-accounts-from-data.html">Password Checkup</a>, which protects account credentials by notifying you if an entered username and password are known to have been compromised in a prior data breach. Using cryptographic techniques, Password Checkup can do this without revealing your credentials to anyone, including Google. Today, Password Checkup protects users across many platforms including <a href="https://security.googleblog.com/2021/02/new-password-checkup-feature-coming-to.html">Android</a>, <a href="https://security.googleblog.com/2019/12/better-password-protections-in-chrome.html">Chrome</a> and <a href="https://blog.google/technology/safety-security/password-checkup/">Google Password Manager</a>.<br /><br />Another example is <a href="https://security.googleblog.com/2019/06/helping-organizations-do-more-without-collecting-more-data.html">Private Join and Compute</a>, an open source protocol which enables organizations to work together and draw insights from confidential data sets. Two parties are able to encrypt their data sets, join them, and compute statistics over the joint data. By leveraging secure multi-party computation, Private Join and Compute is designed to ensure that the plaintext data sets are concealed from all parties.<br /><br />In this post, we introduce the next iteration of our research, Private Set Membership, as well as its <a href="https://github.com/google/private-membership">open-source availability</a>. At a high level, Private Set Membership considers the scenario in which Google holds a database of items, and user devices need to contact Google to check whether a specific item is found in the database. As an example, users may want to check membership of a computer program on a block list consisting of known malicious software before executing the program. Often, the set’s contents and the queried items are sensitive, so we designed Private Set Membership to perform this task while preserving the privacy of our users. <br /><br /><b>Protecting your device information during enrollment</b><br />Beginning in Chrome 94, Private Set Membership will enable Chrome OS devices to complete the enrollment process in a privacy-preserving manner. Device enrollment is an integral part of the out-of-box experience that welcomes you when getting started with a Chrome OS device. <br /><br />The device enrollment process requires checking membership of device information in encrypted Google databases, including checking if a device is enterprise enrolled or determining if a device was pre-packaged with a license. The correct end state of your Chrome OS device is determined using the results of these membership checks.<br /><br />During the enrollment process, we protect your Chrome OS devices by ensuring no information ever leaves the device that may be decrypted by anyone else when using Private Set Membership. Google will never learn any device information and devices will not learn any unnecessary information about other devices. To our knowledge, this is the first instance of advanced cryptographic tools being leveraged to protect device information during the enrollment process.<br /><br /><b>A deeper look at Private Set Membership</b><br />Private Set Membership is built upon two cryptographic tools:<br /><ul style="text-align: left;"><li><span id="docs-internal-guid-3c78fa0f-7fff-ab5d-1002-2e6b786a6fbf">Homomorphic encryption is a powerful cryptographic tool that enables computation over encrypted data without the need for decryption. As an example, given the encryptions of values X and Y, homomorphic encryption enables computing the encryption of the sum of X and Y without ever needing to decrypt. This preserves privacy as the data remains concealed during the computation. Private Set Membership is built upon Google’s <a href="https://github.com/google/shell-encryption">open source</a> homomorphic encryption library.</span></li><li><span id="docs-internal-guid-3c78fa0f-7fff-ab5d-1002-2e6b786a6fbf">Oblivious hashing is a cryptographic technique that enables two parties to jointly compute a hash, H(K, x), where the sender holds the key, K, and the receiver holds the hash input, x. The receiver will obtain the hash, H(K, x), without learning the key K.

Pixel Secure Environments</div><p>The <strong>Google Tensor security core</strong> is a custom designed security subsystem dedicated to the preservation of user privacy. It's distinct from the application processor, not only logically, but physically, and consists of a dedicated CPU, ROM, one-time-programmable (OTP) memory, crypto engine, internal SRAM, and protected DRAM. For Pixel 6 and 6 Pro, the security core’s primary use cases include protecting user data keys at runtime, hardening secure boot, and interfacing with Titan M2<sup>TM</sup>. </p> <p> Your secure hardware is only as good as your secure OS, and we are using <strong><a href="https://source.android.com/security/trusty">Trusty</a></strong>, our open source trusted execution environment. Trusty OS is the secure OS used both in TrustZone and the Google Tensor security core. </p> <p> With Pixel 6 and Pixel 6 Pro your security is enhanced by the new <strong>Titan M2<sup>TM</sup></strong>, our discrete security chip, fully designed and developed by Google. In this next generation chip, we moved to an in-house designed RISC-V processor, with extra speed and memory, and made it even more resilient to advanced attacks. Titan M2<sup>TM</sup> has been tested against the most rigorous standard for vulnerability assessment, AVA_VAN.5, by an independent, accredited evaluation lab. Titan M2™ supports <a href="https://developer.android.com/training/articles/keystore#HardwareSecurityModule">Android Strongbox</a>, which securely generates and stores keys used to protect your PINs and password, and works hand-in-hand with Google Tensor security core to protect user data keys while in use in the SoC. </p> <p> Moving a step higher in the system, Pixel 6 and Pixel 6 Pro ship with <a href="https://android-developers.googleblog.com/2021/10/android-12-is-live-in-aosp.html">Android 12</a> and a slew of Pixel-first and Pixel-exclusive features. </p> <p> <strong>Enhanced Controls</strong> </p> <p> We aim to give users better ways to control their data and manage their devices with every release of Android. Starting with Android 12 on Pixel, you can use the new Security hub to manage all your security settings in one place.

Pixel Secure Environments</div><p>The <strong>Google Tensor security core</strong> is a custom designed security subsystem dedicated to the preservation of user privacy. It's distinct from the application processor, not only logically, but physically, and consists of a dedicated CPU, ROM, one-time-programmable (OTP) memory, crypto engine, internal SRAM, and protected DRAM. For Pixel 6 and 6 Pro, the security core’s primary use cases include protecting user data keys at runtime, hardening secure boot, and interfacing with Titan M2<sup>TM</sup>. </p> <p> Your secure hardware is only as good as your secure OS, and we are using <strong><a href="https://source.android.com/security/trusty">Trusty</a></strong>, our open source trusted execution environment. Trusty OS is the secure OS used both in TrustZone and the Google Tensor security core. </p> <p> With Pixel 6 and Pixel 6 Pro your security is enhanced by the new <strong>Titan M2<sup>TM</sup></strong>, our discrete security chip, fully designed and developed by Google. In this next generation chip, we moved to an in-house designed RISC-V processor, with extra speed and memory, and made it even more resilient to advanced attacks. Titan M2<sup>TM</sup> has been tested against the most rigorous standard for vulnerability assessment, AVA_VAN.5, by an independent, accredited evaluation lab. Titan M2™ supports <a href="https://developer.android.com/training/articles/keystore#HardwareSecurityModule">Android Strongbox</a>, which securely generates and stores keys used to protect your PINs and password, and works hand-in-hand with Google Tensor security core to protect user data keys while in use in the SoC. </p> <p> Moving a step higher in the system, Pixel 6 and Pixel 6 Pro ship with <a href="https://android-developers.googleblog.com/2021/10/android-12-is-live-in-aosp.html">Android 12</a> and a slew of Pixel-first and Pixel-exclusive features. </p> <p> <strong>Enhanced Controls</strong> </p> <p> We aim to give users better ways to control their data and manage their devices with every release of Android.

Outsourcing operations to third-party vendors has become a popular business strategy as it allows organizations to save money and increase operational efficiency. While these are positives for business operations, they do create significant security risks. These vendors have access to critical systems and customer data and so their security posture becomes equally as important.<br /><br />Up until today, organizations of all sizes have had to design and implement their own security baselines for vendors that align with their risk posture.

You can also give them access to some of your data. If you choose to share data with your trusted contacts, the email will include a list of the selected data you wanted to share with them, and a link they can follow to download that data. This can include things like photos, contacts, emails, documents and other data that you specifically choose to share with your trusted contact. You can also choose to set up a Gmail AutoReply, with a custom subject and message explaining that you’ve ceased using the account.</li><li><b>If your inactive Google Account should be deleted: </b>After your account becomes inactive, Google can delete all its content or send it to your designated contacts. If you’ve decided to allow someone to download your content, they’ll be able to do so for 3 months before it gets deleted. If you choose to delete your Google Account, this will include your publicly shared data (for example, your YouTube videos, or blogs on Blogger). You can review the data associated with your account on the <a href="https://myaccount.google.com/dashboard">Google Dashboard</a>. If you use Gmail with your account, you'll no longer be able to access that email once your account becomes inactive.

This program financially rewards developers for enhancing the security of critical open source projects that we all depend on. We are starting with a $1 million investment and plan to expand the scope of the program based on community feedback.</div><div><br /></div><div><br /></div><div><b>Why SOS?</b></div><div><br /></div><div>SOS rewards a very broad range of improvements that proactively harden critical open source projects and supporting infrastructure against application and supply chain attacks. To complement existing programs that reward vulnerability management, SOS’s scope is comparatively wider in the type of work it rewards, in order to support project developers.</div><div><br /></div><div><br /></div><div><b>What projects are in scope?</b></div><div><b><br /></b></div><div>Since there is no one definition of what makes an open source project critical, our selection process will be holistic. During submission evaluation we will consider the guidelines established by the <a href="https://www.nist.gov/system/files/documents/2021/06/25/EO%20Critical%20FINAL_1.pdf">National Institute of Standards and Technology’s definition</a> in response to the recent <a href="https://www.whitehouse.gov/briefing-room/presidential-actions/2021/05/12/executive-order-on-improving-the-nations-cybersecurity/">Executive Order on Cybersecurity</a> along with criteria listed below:<br /><ul style="text-align: left;"><li>The impact of the project:</li><ul><li>How many and what types of users will be affected by the security improvements?</li><li>Will the improvements have a significant impact on infrastructure and user security?</li><li>If the project were compromised, how serious or wide-reaching would the implications be?</li></ul></ul><ul style="text-align: left;"><li>The project’s rankings in existing open source criticality research:</li><ul><li>Is the project included in the <a href="https://www.coreinfrastructure.org/programs/census-program-ii/">Havard 2 Census Study</a> of most-used packages, or does it have a score of 0.6 or above in the <a href="https://github.com/ossf/criticality_score">OpenSSF Critically Score</a> project?</li></ul></ul><b><div><b><br /></b></div>What security improvements qualify? </b></div><div><br /></div><div>The program is initially focused on rewarding the following work:<br /><br /><ul style="text-align: left;"><li>Software supply chain security improvements including hardening CI/CD pipelines and distribution infrastructure. The <a href="http://slsa.dev/">SLSA framework</a> suggests specific requirements to consider, such as basic provenance generation and verification.</li><li>Adoption of software artifact signing and verification. One option to consider is Sigstore's set of utilities (e.g. <a href="https://github.com/sigstore/cosign">cosign</a>).</li><li>Project improvements that produce higher <a href="https://github.com/ossf/scorecard">OpenSSF Scorecard</a> results. For example, a contributor can follow remediation suggestions for the following Scorecard checks:</li><ul><li>Code-Review</li><li>Branch-Protection</li><li>Pinned-Dependencies</li><li>Dependency-Update-Tool</li><li>Fuzzing</li></ul><li>Use of <a href="https://github.com/ossf/allstar">OpenSSF Allstar</a> and remediation of discovered issues.</li><li>Earning a <a href="https://bestpractices.coreinfrastructure.org/">CII Best Practice Badge</a> (which also improves the Scorecard results).</li></ul>We'll continue adding to the above list, so check our <a href="https://sos.dev/#frequently-asked-questions">FAQ</a> for updates.
