Abstract -
This paper proposes a novel scheme of Encryptionthen- compression of color images. In the encryption phase, the original pixel values are rearranged by using pseudorandom permutation with secret key. After decomposing the encrypted data it is divided in to rigid and elastic data. The elastic data alone is compressed by using orthogonal based transformation and closest value calculation. The salient features of the proposed method are near lossless with high security. Performance of this work is also compared with the traditional JPEG algorithm.
