Abstract—JPEG 2000 is an international standard for still image
compression in the 21st century. Part 8 of the standard, named
JPSEC, is concerned with all the security aspects, in particular to
access control and authentication. This paper presents a novel access
control scheme for JPEG 2000 image code-streams. The proposed
scheme is secure against collusion attacks and highly efficient.
The scheme is also very flexible, allowing access control to
JPEG 2000 image code-streams according to any combination of
resolution, quality layer and region of interest. The “encrypt once,
decrypt many ways” property of our scheme is designed to work
seamlessly with the “compress once, decompress many ways” feature
of the JPEG 2000 image code-streams. Our prototype implementation
shows that the scheme is practical and is completely
compatible with the core part of the JPEG 2000 standard.
