Image Security With Different Techniques Of Cryptography And Coding: A Survey

Due to the growth of multimedia applications, the protection of this multimedia data becomes a very important issue of communication and storage; especially when it is transferred over an insecure channel, where apart from preventing illegal data access, images are used in many fields such as medical science and military. The protection of images can be done with image encryption. The majority of encrypted image transmission schemes does not adequately take into account the effect of bit errors occurring during transmission and this issue is considered a problem that should be handled by an efficient coding scheme. Hence, error correction code should be applied after encryption to protect encrypted images against channel errors. In this paper, we present a survey of image encryption techniques and channel coding techniques.
