Design and Implementation of Image Data Sharing through Visual Cryptography System: A compressive Review

A method known as "visual cryptography" encrypts pictures so that they can be seen decrypted without the need for intricate calculations. This method is crucial for safe image sharing because it guarantees the confidentiality of important visual data while it is being transmitted. This research has recognized the importance of this and has proposed a unique method called Segment-Based-Visual-Cryptography-Scheme (SBVCS)-based Pictorial Cryptosystems. There are two primary stages to this approach: Insertion and Removal. In addition to integrating safety features like Modified HMAC-based One-Time- Password generation technique (MHOTP) for better Elliptic-Curve-Cryptosystems (IECC)-based encoding and Baker's map-based encryption, it entails encrypting three initial pictures and two secret pictures using a variety of encryption techniques, including Unplanned grid-based untold picture distributing, Increased Visual-Cryptography-Scheme (EVCS), and Kronecker product-based encrypted data. To generate the best cryptography keys feasible, the SBVCS method is utilized in the Kronecker-product-based cryptography step. With three significant improvements over the traditional Gold Rush-Optimization (GRO) algorithm, the SBVCS is presented as a more sophisticated method. The effectiveness and dependability of the SBVCS in producing ideal keys for Kronecker-product-based encryption are greatly increased by these improvements. Moreover, the MHOTP generation approach is employed in the IECC-based encryption, and the OTPs the results of this procedure serve as the authentication credentials for the encoding phase, so converting the ECC algorithm into an IECC algorithm. Reversing the actions taken during different encryption phases is the decryption process. The importance of this suggested strategy is in its capacity to improve security by combining encryption techniques with security precautions. The method has been put through a number of analyses to confirm its efficacy, and the results show that it can safely transmit and recreate hidden pictures in Visual Cryptography settings.
