important public-key primitive that performs the function of conventional handwritten signatures for entity authentication, data integrity, and non-repudiation, especially within the electronic commerce environment. Currently, most conventional digital signature schemes are based on mathematical hard problems. These mathematical algorithms require computers to perform the heavy and complex computations to generate and verify the keys and signatures. In 1995, Naor and Shamir proposed a visual cryptography (VC) for binary images. VC has high security and requires simple computations.

Visual Cryptography deals with any type of secrets such as printed or pictures, etc. These secrets are delivered into the system in a digital (image) form. The secrets which are in a digital form divided into different parts based on the pixel of the digital secret. These parts are called shares. To visualize the secret, the shares are then overlapped correctly.This paper introduces secure authentication using Visual Cryptography. In any authentication system the major problem is the authenticity of the customer. Due to unavoidable hacking of the database on the internet, it is always difficult to trust the information on the internet. To solve this authentication problem, we are discussing with the two most important topics based on image processing and visual cryptography.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Secure Authentication Using Visual Cryptography","attachmentId":83171144,"attachmentType":"pdf","work_url":"https://www.academia.edu/75378557/Secure_Authentication_Using_Visual_Cryptography","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/75378557/Secure_Authentication_Using_Visual_Cryptography"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="2" data-entity-id="92459934" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/92459934/Novel_authentication_system_using_visual_cryptography">Novel authentication system using visual cryptography</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="104631252" href="https://independent.academia.edu/SiddharthMalik8">Siddharth Malik</a></div><p class="ds-related-work--metadata ds2-5-body-xs">2011 World Congress on Information and Communication Technologies, 2011</p><p class="ds-related-work--abstract ds2-5-body-sm">An array of encryption techniques has been proposed for providing data security. However, most of the traditional cryptography methods require complex algorithms for encryption and decryption. Visual cryptography is a technique which provides confidentiality without any cryptographic knowledge or complex computations. Visual information (e.g. printed text, handwritten notes, pictures, etc.) is encrypted by decomposing it into several images, called shares, in such a way that decryption can be done by human visual system with stacking of the shares. Some important goals while developing a Visual Cryptography scheme is to have (i)optimum number of shares, (ii)good quality of reconstructed image and (iii)keeping the size of share small. This paper aims to provide a comparative study of various Visual Cryptographic schemes based on pixel expansion, no of shares, size and quality of reconstructed image, etc and some real-life applications of visual cryptography. A new authentication system has been proposed which uses the technique of visual cryptography to improve the security level of existing schemes. The application of the system in financial domain is discussed.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Novel authentication system using visual cryptography","attachmentId":95462785,"attachmentType":"pdf","work_url":"https://www.academia.edu/92459934/Novel_authentication_system_using_visual_cryptography","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/92459934/Novel_authentication_system_using_visual_cryptography"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="3" data-entity-id="12039591" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/12039591/Review_of_Visual_Cryptography">Review of Visual Cryptography</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="17059725" href="https://mumbaiunivercity.academia.edu/AnkitaShirodkar">Ankita Shirodkar</a></div><p class="ds-related-work--abstract ds2-5-body-sm">Cryptography is a technique used for secure transformation of information that is secret data in presence of unauthenticated interceptor.

Security has become an inseparable issue as Information Technology is ruling the world now. Cryptography in the study of mathematical techniques related aspects of information security such as confidentialities, data security, entity authentication, but it is not only the means of providing information security, rather one of the techniques. Visual cryptography can be applied for copy right for images, access control to user images ,visual authentication and identification any kind images of images like(normal or digital).Visual cryptography is a new technique which provides information security which user simple algorithm unlike the complex, computationally intensive algorithms used in other techniques like traditional cryptography. This technique allows visual information (pictures, text, etc)to be encrypted in such a way that their decryption can be performed by the human visual system, without any complex cryptographic algorithms. This technique encrypts a secret image into shares such that stacking sufficient number of shares reveals the secret image. Shares are visually presented in transparencies.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Securing Digital Images Using visual Cryptography","attachmentId":105163548,"attachmentType":"pdf","work_url":"https://www.academia.edu/105793589/Securing_Digital_Images_Using_visual_Cryptography","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/105793589/Securing_Digital_Images_Using_visual_Cryptography"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="5" data-entity-id="22936360" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/22936360/A_Visual_Cryptography_Based_Digital_Image_Copyright_Protection">A Visual Cryptography Based Digital Image Copyright Protection</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="44630987" href="https://independent.academia.edu/aqibbuttar">aqib buttar</a></div><p class="ds-related-work--abstract ds2-5-body-sm">A method for creating digital image copyright protection is proposed in this paper. The proposed method in this paper is based on visual cryptography defined by Noor and Shamir. The proposed method is working on selection of random pixels from the original digital image instead of specific selection of pixels. The new method proposed does not require that the watermark pattern to be embedded in to the original digital image. Instead of that, verification information is generated which will be used to verify the ownership of the image. This leaves the marked image equal to the original image. The method is based on the relationship between randomly selected pixels and their 8-neighbors' pixels. This relationship keeps the marked image coherent against diverse attacks even if the most significant bits of randomly selected pixels have been changed by attacker as we will see later in this paper. Experimental results show the proposed method can recover the watermark pattern from the marked image even if major changes are made to the original digital image.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"A Visual Cryptography Based Digital Image Copyright Protection","attachmentId":43464615,"attachmentType":"pdf","work_url":"https://www.academia.edu/22936360/A_Visual_Cryptography_Based_Digital_Image_Copyright_Protection","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/22936360/A_Visual_Cryptography_Based_Digital_Image_Copyright_Protection"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="6" data-entity-id="79543409" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/79543409/Binary_Image_Visual_Cryptography">Binary Image Visual Cryptography</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="199334666" href="https://independent.academia.edu/YHikmat">Yaseen Hikmat</a></div><p class="ds-related-work--metadata ds2-5-body-xs">International Journal of Computer Applications, 2017</p><p class="ds-related-work--abstract ds2-5-body-sm">Modern computer networks make it possible to distribute documents quickly and economically. This is because of the decreasing cost of the equipment needed to copy, print, process the information. The widespread adoption of electronic distribution of material is accompanied with more emphasis on data security. One of the modern data security methods is Visual Cryptography. Visual Cryptography(VC) is the technique that is used for securing data specially image-based secrets such as credit card information, personal health information, military maps and personally identifiable information and commercial identification data. Visual Cryptography allow us to share secret effectively and efficiently, the secret image can be distributed in to two or more shares, when shares are superimposed exactly together the original image would be discovered with human visual system(HVS) without out aid of computer or without performing complicated computations.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Binary Image Visual Cryptography","attachmentId":86222752,"attachmentType":"pdf","work_url":"https://www.academia.edu/79543409/Binary_Image_Visual_Cryptography","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/79543409/Binary_Image_Visual_Cryptography"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="7" data-entity-id="33419925" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/33419925/A_Review_on_Various_Visual_Cryptography_Schemes">A Review on Various Visual Cryptography Schemes</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="65025937" href="https://independent.academia.edu/ijcsbiorg">IJCSBI ORG</a></div><p class="ds-related-work--abstract ds2-5-body-sm">Cryptography is study of transforming information in order to make it secure from unintended recipients or use. Visual Cryptography Scheme (VCS) is a cryptography method that encrypts visual information (picture, printed text, handwritten notes) such that decryption can be performed using human visual system. The idea is to convert this visual information into an image and encypher this image into n different shares (known as sheets). The deciphering only requires selecting some shares out of n shares. The intent of this review paper is to contribute the readers an overview of the basic visual cryptography scheme constructions as well as continued work in the area. In inclusion, we also review some applications that take advantage of such secure system.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"A Review on Various Visual Cryptography Schemes","attachmentId":53471977,"attachmentType":"pdf","work_url":"https://www.academia.edu/33419925/A_Review_on_Various_Visual_Cryptography_Schemes","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/33419925/A_Review_on_Various_Visual_Cryptography_Schemes"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="8" data-entity-id="6861967" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/6861967/A_COMPARATIVELY_STUDY_ON_VISUAL_CRYPTOGRAPHY">A COMPARATIVELY STUDY ON VISUAL CRYPTOGRAPHY</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="2973960" href="https://independent.academia.edu/ijret">Editor IJRET</a></div><p class="ds-related-work--abstract ds2-5-body-sm">The effective and secure protections of sensitive information are primary concerns in commercial, medical and military systems. To address the reliability problems for secret images, a visual cryptography scheme is a good alternative to remedy the vulnerabilities. Visual cryptography is a very secure and unique way to protect secrets. Visual cryptography is an encryption technique which is used to hide information which is present in an image. Unliketraditional cryptographic schemes, it uses human eyes to recover the secret without any complex decryption algorithms and the facilitate of computers. It is a secret sharing scheme which uses images distributed as shares such that, when the shares are superimposed, a hidden secret image is revealed.In this paper we represent various cryptography technique and research work done in this field.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"A COMPARATIVELY STUDY ON VISUAL CRYPTOGRAPHY","attachmentId":33550882,"attachmentType":"pdf","work_url":"https://www.academia.edu/6861967/A_COMPARATIVELY_STUDY_ON_VISUAL_CRYPTOGRAPHY","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/6861967/A_COMPARATIVELY_STUDY_ON_VISUAL_CRYPTOGRAPHY"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="9" data-entity-id="9286444" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/9286444/A_Hash_Based_Visual_Cryptography_Scheme_for_Image_Authentication">A Hash Based Visual Cryptography Scheme for Image Authentication</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="4270915" href="https://ijritcc.academia.edu/ijritcc">International Journal IJRITCC</a></div><p class="ds-related-work--abstract ds2-5-body-sm">In this paper we have proposed a Hash based visual cryptography scheme for image authentication. The secret image to be transmitted is encoded into two shadow images called user share and key share. The Hash cryptographic algorithm is applied on each share, and the resultant Hash codes are concatenated with the shares, and sent to communication participants. The same Hash is used to verify the sender at the receiving end. Then the shares are stacked together to recover the original secret image. From the results obtained in our analysis, we conclude that the proposed scheme provides not only confidentiality but also image authentication</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"A Hash Based Visual Cryptography Scheme for Image Authentication","attachmentId":35549602,"attachmentType":"pdf","work_url":"https://www.academia.edu/9286444/A_Hash_Based_Visual_Cryptography_Scheme_for_Image_Authentication","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/9286444/A_Hash_Based_Visual_Cryptography_Scheme_for_Image_Authentication"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div></div></div><div class="ds-sticky-ctas--wrapper js-loswp-sticky-ctas hidden"><div class="ds-sticky-ctas--grid-container"><div class="ds-sticky-ctas--container"><button class="ds2-5-button js-swp-download-button" data-signup-modal="{"location":"continue-reading-button--sticky-ctas","attachmentId":84455560,"attachmentType":"pdf","workUrl":null}">See full PDF</button><button class="ds2-5-button ds2-5-button--secondary js-swp-download-button" data-signup-modal="{"location":"download-pdf-button--sticky-ctas","attachmentId":84455560,"attachmentType":"pdf","workUrl":null}"><span class="material-symbols-outlined" style="font-size: 20px" translate="no">download</span>Download PDF</button></div></div></div><div class="ds-below-fold--grid-container"><div class="ds-work--container js-loswp-embedded-document"><div class="attachment_preview" data-attachment="Attachment_84455560" style="display: none"><div class="js-scribd-document-container"><div class="scribd--document-loading js-scribd-document-loader" style="display: block;"><img alt="Loading..." src="//a.academia-assets.com/images/loaders/paper-load.gif" /><p>Loading Preview</p></div></div><div style="text-align: center;"><div class="scribd--no-preview-alert js-preview-unavailable"><p>Sorry, preview is currently unavailable.
