Abstract
This paper proposes the hierarchical encryption of Motion JPEG 2000 code streams for layered multicast transmission. JPEG 2000 generates hierarchical code streams and offers flexible scalability in characteristics such as resolution and SNR. The layered multicast encryption proposal allows a sender to multicast hierarchical encrypted JPEG 2000 code streams such that only designated groups of users can de-crypt the code streams. The encrypted bitstreams produced by the proposed method comply fully with JPEG 2000.
