Abstract |
|
In recent years, a significant improvement in multimedia technologies has been observed and therefore, transmission of these data over the network is very common. The network (mainly internet) is not a secure channel and it has a number of security related problems. To achieve security of multimedia data over an insecure channel, a number of encryption methods have been developed. This paper gives a study on different methodology to evaluate image encryption techniques proposed in the literature. Only the visual inspection is not enough and therefore a number of parameters like, correlation coefficient, NPCR. UACI, information entropy, compression friendliness, PSNR, histogram analysis etc., are used, to judge the quality of encrypted images. |
