State of the art of image ciphering: a review

Abstract

The different methods for encryption and decryption in digital images have received growing attention recently. This is due to the availability of new editing software, sophisticated digital cameras, and in addition to tremendous development in communication networks including the Internet, which used by many people to send and receive various types of data including digital images, Although this use on a large scale of this network, but it remains unsafe environment because there are a lot of hackers who are trying to spy on various data sent over the Internet, for this reason has been the development of a range of ways that maintain the security of data including the digital images.
