Abstract: Secure transmission of data in these days is the need of the hour. Here we have used some techniques to effectively encrypt and compress the multimedia data for transmission. Effective transmission of information is required in many fields like defence,medical field etc. In our proposed scheme the sender uses auxiliary information for compression and image reconstruction. Auxiliary information has two parts one part is useful for image compression and the second part is useful for image reconstruction. At receiver side, the original image content can be reconstructed using the compressed encrypted data and the secret key. Result shows the ratio-distortion performance of the proposed scheme is better than that of previous techniques.
