Watermarking is a technique that encrypts one piece of data (the message) within another (the "carrier"). Its typical uses involve media playback, primarily audio clips. 4. WebCryptography is the practice and study of techniques for secure communication in the presence of adversarial behavior [1]. A classical approach to ensure this type of communication is the use of a private key, which is a password code that can be used to encrypt and decrypt the message and must
