Abstract :
In this paper, an efficient and secure encryption scheme for JPEG2000 codestream is proposed. The scheme encrypts each codeblock contribution to a packet (CCP) and does not introduce superfluous JPEG2000 markers in the protected codestream. It achieves full information protection for data confidentiality, and maintains all the advanced features of the original JPEG2000 codestream such as error resilience and scalability. Theoretical analysis and experimental results demonstrate the merits of the proposed scheme.
