A perceptual encryption scheme for Motion JPEG 2000 standard

A new perceptual encryption scheme with an efficient key-management mechanism for the Motion JPEG 2000 based ETC system is proposed in this paper. An ETC system is known as a system that makes image/video communication secure and efficient by using perceptual encryption and image/video compression. Unlike conventional ETC systems, the perceptually encrypted images by the proposed scheme can be efficiently compressed by the Motion JPEG 2000. Moreover, an efficient mechanism to manage a lot of secret keys for video sequences is provided to avoid complex key-management. The experimental results demonstrated that the proposed scheme achieved both acceptable compression performance and enough security for secure image/video communication while remaining compatible with the Motion JPEG 2000 standard.
