Image Encryption Using Block Chain and Chaos for Secure Communication

In the present decade, images have become a valu-able source of information. They play an essential role in medical, the defence, engineering, and other fields. As a result, image information security is a pressing concern. Over the past few years, blockchain has received a lot of attention in the context of trust difficulties and the removal of third parties. The article that follows offers a blockchain-based image encryption approach. The image is encrypted and the values are stored on the blockchain using the suggested technique. In transmission, the blockchain assures confidentiality and anonymity. On the basis of NPCR, UACI, and information entropy evaluation, the robustness of the proposed approach has been assessed against differential assault. Entropy analysis is used to illustrate the strength of the system against a brute force assault. The result came close to the optimal value of 8. The suggested method is also demonstrated to be effective in preventing data loss during transmission.
