In recent years we have seen significant growth in multimedia based Internet applications and multimedia commerce. The advancements in multimedia commerce resulted has in a rapid growth, in the amount of multimedia data transferred over network. The multimedia data stored on the web servers as well as the data transferred over the network needs to be protected from piracy and eavesdropping. Hence, there is a strong need for encrypting the multimedia content. But owing to the size of the multimedia content and real time requirements for encoding, transmitting and decoding the multimedia content, usage of standard encryption/decryption schemes prove to be an overhead. Hence lightweight encryption schemes are gaining popularity. The schemes are designed using structure of the multimedia content, and partially encrypting the content such that it results in insertion of sufficient noise to make the content unintelligible. In this paper we present a scalable and secure lightweight encryption scheme for image and video data in bit domain. The scheme in addition to being secure and scalable has negligible impact on compression.
