Abstract

Most of the existing encryption algorithms are best suited for textual data and cannot directly be applied on images since image data have special features such as bulk capacity, high redundancy and high correlation among pixels that imposes special requirements on the encryption technique used. Therefore, image security has its own special requirements that lead to different thoughts to protect digital data. In this paper, the proposed system would overcome the problem of security and storage by encrypting and compressing the image. The image would be encrypted using a key matrix and then compressed using the proposed algorithms for encryption and compression on the sender side. Similarly on the receiver side the received image would be decompressed and decrypted using the same key. The proposed encryption algorithm encrypts the pixel values by exoring these values with the key generated by the key generation algorithm and then compresses these encrypted pixel values using a specific encoding scheme. This system can be used in any application where image needs to be sent over an insecure channel.
