A novel encryption method with associative approach for gray-scale images

This paper introduces a novel method for encrypting images with an associative approach. We use a symmetric cryptosystem. The encryption method divides the gray-scale image in n squares with which a Morphological Associative Memory is built. Then, the information from the image is stored in the array which represents the memory. The meaning of the array is very difficult to decipher without the private key and the previous knowledge for operating the associative memory. The original and the recovered images were correlated, and the recovering is 100% in all cases.
