This paper describes the most representative algorithms and standards for the encryption of data, digital images and MPEG video. The general model a typical encryption/decryption system about the security principle is discussed. Data encryption mainly is the scrambling of the content of data, text, image, audio, and video and to make the data unreadable, invisible or incomprehensible during ciphertext transmission. The goal is to protect the content of the data against the attackers. The reverse of data encryption is data decryption, which recovers the original data. There are two types of encryption/decryption key: the public-key system and the private-key system. The most promising features are joint lossless compression, joint encryption and hiding based on SCAN language which analyses the unique properties of digital image and video and search for high security algorithms to reduce the overall computational cost.
