ABSTRACT:
A header object for a data file is comprised of sub-objects which specify properties of the data stream and contains information needed to properly verify and interpret the information within the data object. In order to allow the protection of any set of sub-objects without requiring that the sub-objects follow any specific ordering, a new sub-object is introduced which includes region specifiers identifying regions within sub-objects and verification information for those regions. This new sub-object in the header object allows the modification of non-protected regions and reorganization of sub-objects in a header without invalidating verification information.
