Techniques for database structure and management

A database system for securely managing identity (ID) related information for use in access control for a wireless communication network, the database system comprising:

• an ID management and service access controller system (IDMS/ACS) for managing access to the wireless communication network based on information contained in a user ID profile (UID-PR);
• a UID-PR exporter;
• a UID-PR importer;
• and
• an ID-database management system (ID-DBMS) for providing an interface between the IDMS/ACS and the UID-PR importer and UID-PR-exporter.

A database system for storing and protecting digital rights management (DRM) content using common trans-ciphering, the system comprising:

• at least one DRM system;
• for using and providing DRM encrypted content objects (COs);
• a common trans-ciphering (CTC) unit for re-encrypting different content objects originally encrypted for different DRM systems with different encryption/decryption algorithms and for storing them in a protected memory.
• a database management system (DBMS) for receiving COs from the least one DRM system and providing them to the CTC unit only if the COs satisfy predefined rules and classification requirements.
