Selective Image Encryption and Compression Technique: Review

الملخص

In line with a growing need for data and information transmission in a safe and quick manner, The security becomes an important issue of communication and storage of image due to the growth of multimedia application. Encryption is one of the ways to ensure high security.  Images are used in many fields such as military and medical science. researches on image protection and security through a combination of cryptographic and compression techniques begin to take form. The combination of these two methods may include into three categories based on their process sequences.  The first category, cryptographic technique followed by compression method.  The second combination, compression technique followed by the cryptographic method, has an advantage where the compression technique can be lossy, lossless, or combination of both. The third category, i.e. compression and cryptographic technologies in a single process either partially or in the form of compressive sensing .
