Abstract

A system and method for data rights management across multiple data rights
management architectures is disclosed. The system and method solves the
problems posed by multiple incompatible data rights management
architectures. In particular, a data rights management clearing house is
provided that generates permits, permit classes, and enables content
packaging across multiple data rights management architectures. Consumers
may acquire rights to content packaged with different data rights management
architecture from the single data rights management clearing house.
Additionally, the system and method enables content packagers to package
content with multiple data rights management architectures. Finally, the
data rights management clearing house provides consumers with a single
location from which to manage data access rights and restore data access
rights that have been lost.
