Encryption and Decryption Process of RGB Colour Image Using by Matrix Method

In this research work, we suggest a new technique for RGB colour countenance encryption based on change matrix. The colour concept is encrypted into Red, Green and Blue channels place each channel uses a double permutation key method for assigning a new colour to each pixel of RGB colour countenance. Each channel is encrypted with a method known as double change key encoding, that assigns a various color to each pel of an RGB color image. Additionally, we present a novel approach of detached block encryption. The number of possible encryptions is provided along with a particularized study of the encryption of a 9-pixel representation. Additionally, the Matrix representation efficiently conveys the explanation process.
