Abstract

Systems and methods for incorporating restricted access to feature vectors are described. A method is described for storing and accessing feature vectors relating to individuals in digital images. One or more individuals are identified within photos, and feature vectors are generated for individuals in one or more photos. User profiles are downloaded from a database over a network. The feature vectors and downloaded user profiles are grouped. The face tagging system collects tags for the generated grouped feature vectors for generating enhanced user profiles for the individuals, and the enhanced user profiles are stored in a storage resource.

Claims

1. A computer-implemented method for storing and accessing feature vectors relating to individuals in digital images, comprising:

identifying one or more facial region within photos;

generating feature vectors for the one or more facial regions in one or more photos using a face tagging system;

downloading user profiles from a database over a network;

grouping the feature vectors and downloaded user profiles;

collecting, by the face tagging system, tags for the generated grouped feature vectors for generating enhanced user profiles for the individuals;

storing the enhanced user profiles in a storage resource;

establishing an access level for the stored feature vectors and associated tags;

receiving an access request from a remote system to the stored feature vectors and associated tags;

defaulting to an access level wherein the remote system can access only feature vectors associated with a user of the remote system; and

setting an access level wherein all identified individuals within the photos have access to the feature vectors.

2. The method of claim 1, further comprising:

upon storing the enhanced user profiles to the storage, performing one of;

sending the enhanced user profiles back to the database; and

sharing the enhanced user profiles with other face tagging systems.

3. The method of claim 1, wherein the user profiles further comprise a user identity and feature vectors.

4. The method of claim 3, wherein the user identity comprises a name, e-mail address, descriptor, or other identifying information.

5. The method of claim 1, wherein setting an access level is performed according to user input.

6. The method of claim 1, further comprising:

for subsequently received photos, utilizing the enhanced feature vectors to identify one or more individuals; and

receiving confirmation by a user regarding the identification of the one or more individuals.

7. The method of claim 1, further comprising storing the established access levels for the stored feature vectors and associated tags in a server.

8. The method of claim 1, wherein receiving an access request from a remote system to the stored feature vectors and associated tags comprises:

receiving identification information relating to the user of the remote system;

based on the identification information, granting access to the stored feature vectors in the database according to the established access level.

9. The method of claim 8, wherein granting access to the stored feature vectors comprises sending a portion of the feature vectors stored in the database to the remote system over a network.

10. The method of claim 8, wherein granting access to the stored feature vectors comprises accessing the stored feature vectors based on at least one of:

date information, time information, and one or more tag relationships.

11. A system for storing and accessing feature vectors relating to individuals in digital images, comprising:

a feature vector module for receiving digital photos and user profiles, extracting feature vectors of individuals;

a correlator configured to group the feature vectors and the user profiles according to individuals;

a tag module configured to receive a tag for the generated grouped feature vectors for generating enhanced user profiles for the individuals;

establishing an access level for the feature vectors and associated tag;

receiving an access request from a remote system to the feature vectors and associated tag;

defaulting to an access level wherein the remote system can access only feature vectors associated with a user of the remote system; and

setting an access level wherein all identified individuals within the photos have access to the feature vectors.

12. The system of claim 11, wherein the tag module further comprises sending the enhanced user profiles back to a database.

13. The system of claim 12, wherein the database further comprises sharing the enhanced user profiles with other face tagging systems.

14. The system of claim 11, wherein the system further comprises a restricted access module configured to establish an access level for the each of the individuals of stored feature vectors and associated tags, the restricted access module further configured to receive an access request from a remote system for the stored feature vectors and associated tags.

15. The system of claim 14, wherein the restricted access module is further configured to store the established access levels in the database.

16. The system of claim 14, wherein the restricted access module is further configured to receive identification information regarding a user of the remote system as part of receiving an access request.

17. The system of claim 16, wherein the restricted access module determines if the received identification information regarding a user of the remote system matches any tags in the database.

18. The system of claim 14, wherein the restricted access module establishes customized access levels for the stored feature vectors according to user input.

19. The system of claim 11, wherein the tag comprises at least one of:

name, e-mail, and a login identifier.

20. A non-transitory computer readable medium;

comprising computer-program instructions executable by a processor, the computer-program instructions comprising instructions for;

generating feature vectors for individuals in digital photos received by a face tagging system;

downloading user profiles from a database over a network;

grouping the feature vectors and downloaded user profiles;

receiving tags for the generated grouped feature vectors and downloaded user profiles for generating enhanced user profiles for the individuals;

storing the enhanced user profiles to a storage resource;

establishing an access level for the stored feature vectors and associated tags;

receiving an access request from a remote system to the stored feature vectors and associated tags;

defaulting to an access level wherein the remote system can access only feature vectors associated with a user of the remote system; and

setting an access level wherein all identified individuals within the photos have access to the feature vectors.

21. The computer-readable medium of claim 20, further comprising establishing an access level for each of the user profiles;

and

granting access by a second face tagging system to feature vectors according to the established access level for each of the user profiles.

22. The computer-readable medium of claim 21, further comprising instructions for receiving identification information relating to the user of the second face tagging system.

23. The computer-readable medium of claim 20, further comprising instructions for:

utilizing the accessible feature vectors to identify one or more individuals for subsequently received photos; and

receiving confirmation regarding the identification of the one or more individuals.

24. The computer-readable medium of claim 20, wherein the instructions for establishing an access level for each of the user profiles establishes access levels according to one or more of:

user input; and

default access levels.
