In this paper we have proposed an image crypto-compression system that guarantees a secure storage and transfer while preserving the performance of the used compression method. Regarding compression, we have chosen to use the discrete cosine transformation (DCT), Huffman coding and rle because of their efficiency and their use in most current crypto-compression systems. As for encryption, we have made the choice to use the chaos for its good cryptographic properties. Experimental results confirm that our system is efficient, secure and greatly improve the compression ratio of the image while maintaining the performance of the encryption algorithm.
