A STATE-OF-THE-ART REVIEW ON IMAGE ENCRYPTION TECHNIQUES AND BIO CRYPTOGRAPHY

Abstract

Cryptography defends against unauthorized access to data stored on the network. High-security data transfer is very important. Biometrics is a distinctive feature of human beings and is a well-recognized individual authenticator. The sharing of all medical data has been carried out widely in the world. The Advanced Encryption Standard (AES) encryption algorithm is used as the most efficient cryptographic algorithm for high security. Thanks to its long-term security, this algorithm is widely preferred and has a broad range of applications and protocols. Due to the massive sharing of confidential information, the security of data over the network has become a significant problem. In different fields, such as hospitals, science, medical applications, etc., cryptography is used for secret transmission of knowledge. This paper is an analysis of familiar encryption strategies from which researchers will learn the principle of effective methods to be used..
