This paper proposes a scalability coding on encrypted images, especially resolution scalability on lossy compression images. In the compression stage, the input gray level image is compressed using Diagonal Min-Max Block Truncation Coding technique. The compressed input image is encrypted using pseudorandom numbers masked by modulo-256, and then the encoded bit streams are transmitted. The pseudorandom numbers generated will be the encrypted key and the same is shared to the receiver. In the receiver side, the encoded bit stream is decrypted by using the shared encrypted key, which gives the compressed pixel value. Then the original image is reconstructed by using Diagonal Min-Max Block Truncation Coding Technique.
