Abstract

A system is disclosed for providing interoperability between a plurality of data protection systems. The system includes an ontology (3) configured to store definitions (12) of concepts (4) relating to interface elements of at least two different data protection systems including a first data protection system (1) and a second data protection system (2); and a mapping generator (5) configured to generate a mapping between at least one interface element of the first data protection system (1) and at least one interface element of the second data protection system (2), based on the ontology (3). The system comprises a message converter (16) configured to receive a message generated by the first data protection system (1), convert the message based on the mapping to obtain a converted message, and transmit the converted message to the second data protection system (2).

Claims

1. A system for providing interoperability between a plurality of digital data protection systems, comprising:

an ontology configured to store definitions of concepts relating to interface elements of at least two different digital data protection systems including a first data protection system and a second data protection system; and

a computer-implemented mapping generator configured to generate a mapping between at least one interface element of the first data protection system and at least one interface element of the second data protection system, based on the ontology.

2. The system according to claim 1, comprising a message converter configured to receive a message generated by the first data protection system, convert the message based on the mapping to obtain a converted message, and transmit the converted message to the second data protection system.

3. The system according to claim 1, wherein the first data protection system comprises an access control system and wherein the second data protection system comprises a digital rights management system.

4. The system according to claim 3, wherein the mapping generator is arranged for mapping concepts involved in an access control policy and a digital rights management license.

5. The system according to claim 3, wherein the access control system comprises an access control server and wherein the digital rights management system comprises a digital rights management client, and wherein the mapping generator is configured to generate a mapping between at least one interface element of the access control server and at least one interface element of the digital rights management client, based on the ontology.

6. The system according to claim 1, wherein the mapping generator is arranged for generating the mapping based on the definitions of the concepts.

7. The system according to claim 6, wherein the mapping generator is arranged for matching a definition of a concept of the first data protection system with at least one definition of a concept of the second data protection system.

8. The system according to claim 1, wherein the ontology is arranged for storing representations of relationships (13) between the concepts of the different data protection systems, and wherein the mapping generator is arranged for generating the mapping based on the relationships between the concepts defined in the ontology.

9. The system according to claim 1, wherein the mapping generator is arranged for mapping an interface element of the access control system at least partly into a system constraint of a digital rights management system.

10. The system according to claim 1, further comprising an ontology updater (14) for including a concept and definition of a new interface element in the ontology.

11. The system according to claim 10, wherein the ontology updater is arranged for determining a relationship between the new interface element and an existing interface element, based on the definitions, and storing the relationship in the ontology.

12. The system according to claim 1, wherein the mapping generator is arranged for generating mappings for concepts of a plurality of different digital rights management systems based on different digital rights management standards.

13. A workstation comprising the system according to claim 1.

14. A computer-implemented method of providing interoperability between a plurality of digital data protection systems, comprising:

storing definitions of concepts in an ontology, the concepts relating to interface elements of at least two different digital data protection systems including a first data protection system and a second data protection system; and

generating a mapping between at least one interface element of the first data protection system and at least one interface element of the second data protection system, based on the ontology.

15. A computer program product comprising instructions for causing a processor system to perform the method according to claim 14.
