Analysis of Color Image Noising Process

RGB color image is one of the most papular digital data type used in data transmission, it can contain valuable and secret information, so protecting it is an important issue. In this paper research we will analyse the efeects of adding-subtracting a selected and defined noise signal to color image, this noise signal will be huge to cover any image with any size, it will be saved and used as a secret signal to encrypt-decrypt color images. The noise signal will be represented by a simple mathematical equation, we will vary the noise parametor and measure the quality parameters MSE and PSNR between the original image and the encrypted and decrypted images.
