Abstract


Encryption plays an important role to guarantee classified transmission of information over web. Over the years images have emerged as one of the most widely used forms of communication. Various methods have been developed at spatial, frequency and hybrid domains for image encryption. Commonly to transmit information faster over network compression is used. Recently there have been advancements in combining encryption and compression together. In these paper techniques for application of combined encryption and compression over digital images proposed over recent years have been surveyed. This paper also points out some of the future directions which may lead to new path to improve current models.

Keywords


Image encryption, Image compression, Data Hiding, DCT, JDHC, PSNR, CRT.
