Abstract :

In many applications, image sending should be done very secretly. This secret sending of image can be done by image encryption and compression. Image encryption should be done before compression to provide more security. This paper proposes a method for compressing encrypted images where the image encryption is done by permutation. The compression is done in two layers such as base layer and enhancement layer. In the base layer, downsampling of the image is first done and adaptive arithmetic compression is applied to each patches of the downsampled image. In the enhancement layer, pixels for coding are selected by reconstruction error and greedy strategy. A multiscale technique is applied by the decoder for the reconstruction of compressed image. Our evaluations show that the reconstructed image should possess the quality of original image.
