A scalable message authentication scheme for JPEG2000 codestreams

Most scalable authentication schemes for images proposed in literature only consider about general signature schemes which use an unkeyed one-way hash function to generate hash digest. In this paper, we propose a scalable message authentication scheme for JPEG2000 codestream utilizing a keyed hash function to provide both integrity and origin authentication. The proposed scheme adapts the Merkle hash tree-based authentication in [3], combining with a flexible packet´s secret key generation for message authentication codes. Moreover, the properties of JPEG2000 codestream structure are completely maintained in our proposed authentication scheme.
