An Overview of Crypto-Compressive Based on Selective Coding

Enas Kh Alamiry, Faisal G. Mohammed

Abstract: Image encoding (visual cryptography) is special encryption technique to hide the information contained within an image. In such a way it cant be decrypted or recognized by neither human visual system (HVS) nor cryptanalysis algorithms. Partial image encryption have become very popular due to rapid evolution in information technology and visual communications over open networks, it is considered crucial to real time applications that need to be very fast and entirely secured, where the digital data must kept intact from eavesdroppers and unauthorized access. Most of todays techniques encrypt all of the image data which consumes tremendous amount of time and computational payload. This paper introduces the image Encryption strategy along with its main categories (full and partial encryption), partial Encryption sub-categories, and the leading schemes proposed for Partial Image Encryption (PIE) that only apply the encryption algorithm to merely a portion of the image data which produces huge reduction in processing time and computational Complexity

Keywords: Partial Encryption, Selective Encryption, Cryptography, Image Scrambling
