ISO/IEC 15444-8:2007 specifies the framework, concepts, and methodology for securing JPEG 2000 codestreams. It defines

• a normative codestream syntax containing information for interpreting secure image data;
• a normative process for registering JPSEC tools with a registration authority delivering a unique identifier;
• informative examples of JPSEC tools in typical use cases;
• informative guidelines on how to implement security services and related metadata.

It does not describe specific secure imaging applications or limit secure imaging to specific techniques, but creates a framework that enables future extensions as secure imaging techniques evolve.
