En-cryption of text or images, which cover the highest percentage of the multimedia, is most important during secure transmission of information. There are so many different techniques that should be used to protect confidential image data from unauthorized access. In this paper, literature review of different image encryption and description techniques from 2013 to 2015 have been discussed from which researchers can efficient techniques to be used. Moreover, it provides the various aspects used for the image security.
