This document specifies the framework, concepts, and methodology for securing JPEG 2000 codestreams. The scope of this document is to define:

1)？a normative codestream syntax containing information for interpreting secure image data;

2)？informative examples of JPSEC tools in typical use cases;

3)？informative guidelines on how to implement security services and related metadata.

The scope of this document is not to describe specific secure imaging applications or to limit secure imaging to specific techniques, but to create a framework that enables future extensions as secure imaging techniques evolve.？
