Color Image Encryption-Decryption using RANDOM Noise and PMT

Abstract: RGB color images are among the most important types of digital data circulating in the Internet and through various social media.  RGB color image may contains confidential information, or the signal may be of a personal nature, which requires preventing its understanding from unauthorized entities or persons and therefore this signal must be encrypted.  In this paper, we will discuss a new method for encrypting the RGB color images based on adding a random noise and image rearrangement.  The method will be run to measure its efficiency and the extent to which it achieves the level of security and protection. The experimental results will be analysed to prove the proposed method efficiency factors.

Keywords: RGB color image, YIQ image, random noise, PMT, MSE, PSNR, encryption time, decryption time, requirements.
