A Survey of RGB Color Image Encryption Methods

The digital RGB color image is one of the most important types of data circulated through the Internet and through various social media, it can contain secret and personal information, so protecting it is an important issue. In this paper research we will analyse some efficient methods used to encrypt-decrypt color images, these methods include XORING, blocking and reordering and selective random signal methods. For each method we will experimentally find the parameters MSE, PSNR , encryption time and throughput. A comparison of the methods results will be done in order to select the best method of color image encryption-decryption.
