A Novel Image Encryption Technique Using RGB Pixel Displacement for Color Images

In the present scenario when all data is in network, cloud or some data center, security and protection of data is a major concern. Encryption is one of the techniques used for this purpose. Image encryption is applied for protecting images from different kinds of attacks. Image Encryption is possible by a kind of transposition in color images or 3D images by displacing the rgb components of the color image. This paper presents a method for encryption and decryption of Color images using RGB pixel displacement. In the proposed method the original plain image is split into its basic three components, that is the RGB components and the key image is also split into RGB Components. Further by application of XOR operation and scrambling of the three components the cipher image is generated. This method is suitable for encrypting 3D images. The algorithm is implemented in MATLAB environment and tested on various color images.
