Abstract

Access rights to content items, such as personal photos etc, is determined in response to content metadata and requester metadata. A plurality of content items is stored in a content item store. An access right processor determines content metadata for the plurality of content items. When a request for a content item is determined, the access right processor determines requester metadata for the request. The requester metadata comprises data of a characteristic of a requester of the request. The access right processor then determines access rights in response to the content metadata and the requester metadata. If a positive access right is determined, the requested content item may be sent to the requester. The access right may further be determined in response to past usage data or context data for the content items. The invention may allow an improved and automated access right management.

Claims

1. An apparatus comprising:

memory for storing a plurality of content items; and

a processor coupled to the memory and arranged to determine content metadata for the plurality of content items;

receive a request for a first content item of the content items;

determine requester metadata for the request, the requester metadata comprising data of a characteristic of a first requester of the request; and

determine an access right for the first requester to the first content item in response to the content metadata and the requester metadata.

2. The apparatus claimed in claim 1 wherein the processor is further arranged to determine past usage data for the plurality of content items;

and to further determine the access right in response to the usage data.

3. The apparatus claimed in claim 2 wherein the processor is arranged to determine the access right as a positive access right if the first content item meets a similarity criterion with respect to another content item for which the past usage data indicates that a requester meeting a similarity criterion with respect to the first requester has obtained a positive access right.

4. The apparatus claimed in claim 1 wherein the processor is further arranged to determine contextual metadata for the plurality of content items;

and to further determine the access right in response to the contextual metadata.

5. The apparatus claimed in claim 4 wherein the contextual metadata relates to a user context for a user associated with each of the plurality of content items.

6. The apparatus claimed in claim 1 wherein the processor is further arranged determine a category of the first requester in response to the requester metadata;

and to determine the access right as a positive access right in response to a determination that at least one other requester belonging to that category has positive access rights.

7. The apparatus of claim 6 wherein the processor is arranged to determine the access rights of the at least one other requester in response to an access right determination for a previous request by the at least one other requester for the first content item.

8. The apparatus claimed in claim 1 wherein the processor is further arranged determine a category of the first content item in response to the content metadata;

and to determine the access right as a positive access right in response to a determination that the first requester has a positive access right to at least one other content item belonging to that category.

9. The apparatus of claim 8 wherein the processor is arranged to determine the access rights for the at least one other content item in response to an access right determination for a previous request by the first requester for the at least one other content item.

10. The apparatus of claim 1 wherein the processor comprises access right associations linking at least a first content item characteristic with a first requester characteristic;

and wherein the processor is arranged to determine a positive access right if a requester and a content item of a request by the requester are linked by an access rights association.

11. The apparatus claimed in claim 10 wherein the processor is further arranged to determine a requester category of the first requester in response to the requester metadata;

and to determine the access right in response to an access rights association for at least one other requester of the requester category.

12. The apparatus claimed in claim 10 wherein the processor is further arranged to determine a content category of the first content item in response to the content metadata;

and to determine the access right in response to an access rights association for at least one content item of the content category.

13. The apparatus of claim 10 wherein the processor is arranged to generate access right associations in response to a determination of an access right for a requester for a content item.

14. The apparatus of claim 1 wherein the processor is arranged to determine a positive access right if the content metadata for the first content item comprises an association to a characteristic of the first requester.

15. The apparatus of claim 14 wherein the characteristic is an identity.

16. The apparatus of claim 1 wherein the processor is arranged to determine the requester metadata in response to locally stored data for the first requester.

17. The apparatus of claim 1 wherein the processor is arranged to determine the access right in response to a user defined access right for at least one different content item.

18. The apparatus of claim 1 wherein the apparatus comprises a user interface for presenting the access rights to the user.

19. The apparatus of claim 1 wherein the apparatus comprises an interface for providing access for the first requester to the first content item only if a positive access right is determined.

20. A method of determining access rights to content items comprising:

storing a plurality of content items;

determining content metadata for the plurality of content items;

receiving a request for a first content item of the content items;

determining requester metadata for the request, the requester metadata comprising data of a characteristic of a first requester of the request; and

determining an access right for the first requester to the first content item in response to the content metadata and the requester metadata.
