Popular application of multimedia technology and increasing transmission ability of network gradually leads us to acquire information directly and clearly through Images. The digital images, which are transmitted over the internet, must be protected from unauthorized access during storage and transmission for communication, copyright protection and authentication purposes. This can be accomplished using image encryption which is an intelligent hiding of information. In this paper, I survey on existing work which is used different techniques for image encryption and also give the general introduction about cryptography. | | Keywords : | | - Symmetric key cryptography,
