A Review On Different Approaches of Selective Image Encryption for Compressed and Uncompressed Images

Due to rich growth of multimedia application it becomes essential to secure and compress the multimedia data. Digital distribution network is a medium used to transfer the multimedia data. It is obvious to provide security against these multimedia data for unauthorized access or use. This is achieved by applying encryption. The encryption is a mathematical process which converts an original message into unintelligible message. There are a lot of encryption rules which can be applied to secure the simplest form of multimedia data (text data) and not suitable for images and videos having large files size. Selective encryption is a modern technique to lessen the computational requirements for large amount of multimedia data in distribution networks with diverse client device capabilities. In this paper, we have studied about principle and working of Selective Image Encryption.
