Abstract
A hybrid digital rights management (DRM) system includes a hybrid digital rights management server (RMS server) connected to first and second RMS servers and a client computer. The hybrid RMS server stores a policy mapping table that maps its DRM policies to remote DRM policies on the first or second RMS servers, and can also create policies that satisfy the schema requirements of the first or second RMS server using policies stored in the hybrid RMS server. When the hybrid RMS server receives a document protection request from the client computer, it extracts the filename extension for the document to be protected, and uses the filename extension to select one of the first and second RMS servers as a target RMS server. The document is protected by the target RMS server, and also added to a protected document database on the hybrid RMS server.
