Abstract

An apparatus comprises a content item receiver which receives a content item such as a digital photo or an audio or video clip. A user preference model generates data indicative of user preferences for content item access. An access rule processor determines a set of self-governance rules for the first content item in response to the user preference model. The self-governance rules are indicative of allowable actions for the first content item in other devices. A file processor includes the set of self-governance rules with the content item and a network interface transmits the content item to a second apparatus . The second apparatus comprises functionality for restricting access to the content item in accordance with the set of self-governance rules. The invention may provide improved access rights management and in particular for personal content items.

Claims

1. An method for content access rights management comprising:

a communication unit performing;

receiving a picture along with metadata related to the picture;

storing a user preference model indicative of user preferences for access to the picture and the metadata related to the picture, wherein the user preference model allows access to the picture, but restricts access to the metadata related to the picture; and

transmitting the picture and the metadata to a second apparatus, wherein the picture and/or the metadata transmitted to the second apparatus has embedded self governance rules within the picture and/or metadata, the embedded self governance rules allowing access to the picture, but restricting access to the metadata related to the picture.

2. The method of claim 1 wherein the user preference model is a privacy preference model indicative of privacy preferences for a user associated with the picture.

3. The method of claim 1, wherein the self-governance rules are determined in response to a relative prioritisation of different parameters of the user preference model.

4. The method of claim 3, wherein access user characteristics have a higher prioritisation than access context characteristics which have a higher prioritisation than content characteristics for the picture.

5. The method of claim 1 further comprising modifying the user preference model in response to a user preference determination for a second picture.

6. The method of claim 1 further comprising generating policy rules in response to the user preference model, wherein the set of self-governance rules are determined in response to the policy rules.

7. The method of claim 6 further comprising validating a set of policy rules.

8. The method of claim 1 further comprising determining the set of self-governing rules in response to a generation of self-governing rules for previous pictures.

9. The method of claim 1 further comprising determining the set of self-governing rules in response to a content characteristic of the picture.

10. The method of claim 1, further comprising detecting a discrepancy between a self-governance rule for the picture and a self-governance rule for at least one previous picture and generating a user alert in response to a detection of the discrepancy.

11. The method of claim 1, wherein the picture comprises a plurality of pictures and wherein the set of self-governance rules corresponds to different access rights for at least a first picture and a second picture.

12. The method of claim 11, wherein the set of self-governance rules comprises relationship information for the plurality of picture elements.

13. The method of claim 11, further comprising removing in response to the set of self-governance rules at least one of the plurality of picture elements from the picture before transmission to the second apparatus.

14. A picture distribution system comprising:

a first apparatus comprising;

a processing device having access to a stored a user preference model indicative of user preferences for picture access and metadata access ,the metadata related to the picture, the processing device adapted for;

determining a set of self-governance rules for the picture and metadata in response to the user preference model, the self-governance rules for use by other devices including a second apparatus to determine allowable actions for the first picture and the metadata in other devices, wherein the allowable actions include an ability to view the picture and restricting access to the metadata related to the picture, including the set of self-governance rules with the picture and/or metadata , and

transmitting the picture, the metadata, and the set of self-governance rules to the second apparatus, wherein the self-governance rules allow the second apparatus to view the picture, but restricts access to the metadata.

15. A picture distribution system as claimed in claim 14 wherein processing device is arranged to allow access to only a subset of a plurality of picture elements of the picture.

16. A picture distribution system as claimed in claim 14, wherein the set of self-governance rules is context sensitive.

17. A picture distribution system as claimed in claim 14, wherein the processing device is further adapted for encrypting at least one picture element of a plurality of picture elements of the picture.
