Encryption methods include transposition by rearranging the data to be encrypted so as to make them unintelligible. For example, it rearranges geometrically the data to make them visually unusable. In this paper, we propose a new encryption method of still images based on the affine encryption principle to achieve a transposition and perform some manipulations to reduce the quantity of bits to be processed on an image. The application of this method on the still images, gave us a high degree of safety laws after a security measure introduced by Shannon and a minimum processing time is proportional to the number of pixels, while operations encryption and decryption. The comparison of this approach with the encryption method using injection of noise on the architecture of artificial neural networks, showed its good performance.
