This book summarizes that information technology is significant in supporting computer applications to many users and establishments worldwide like information security, information hiding, and information retrieval. All users, who use multimedia such as images, audio, video, and text, may need to protect information from attacks while sending or receiving them through channels. The proposed algorithm gives good results by applying some statistical tests as well the proposed algorithm achieved encryption rates of about 0.134136 and 0.106204 for decryption rate. Finally, it is possible to encrypt partial images instead of full image encryption. Also, it can be applied as a block cipher instead of a stream cipher to get good results. As well as it can be developed by compression of the plain image with an image key to reducing the cost of data transition.
