Secure JPEG 2000-JPSEC
The Joint Photographic Experts Group (JPEG) has recently rolled out a new still image coding standard called JPEG 2000. This standard integrates an efficient image compression scheme with functionalities required by multimedia applications, such as progressiveness up to lossless coding, region of interest coding, and error resiliency. Security is a concern in many applications, and therefore also a desired functionality. This paper provides readers with insights and examples of how to combine security solutions with JPEG 2000 compression. Tools for JPEG 2000 compressed image integrity, access control, and copyright protection are presented. They can be either applied to a JPEG 2000 codestream or directly integrated into the coding/decoding operations, resulting in a fully compliant JPEG 2000 image.
