信息技术—JPEG 2000图像编码系统：安全的JPEG 2000

[中文适用范围]： 本文件提供了一种语法，允许对JPEG 2000编码的图像数据应用安全服务，同时保持JPEG 2000固有的特性，如可伸缩性以及访问各种空间区域、分辨率级别、颜色组件和质量层。 [外文原描述]： 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.
