Compressing Encrypted Images and Data Using Auxiliary Information

Smita Kadam; Prof. Meena Chavan

Now-a-days, in every sector, security and reliable end to end transmission is of main concern. Encrypting an image before transmitting is considered. Encryption enhances the security of file or an image by shuffling the content which can be unscrambled by only one who knows the encryption key. If this image is transferred on insufficient bandwidth it won’t be transmitted. Hence for effective transmission, compression of encrypted image is needed. Compression encodes information, reducing its bandwidth or bits required. This paper proposes transmission of compressed image with hidden encrypted data using auxiliary information.
