Abstract

Privacy centric feature analysis. A secure set of multiple mapped features is selected and provided to a mobile device. Each mapped feature maps a sharable feature to a matching criterion for an item of protected information and no combination of mapped features for a secure set are unique to an individual item of protected information. Privacy compliance instructions enable the mobile device to select a mapped feature from a received set of mapped features by identifying an item of protected information available to the mobile device which corresponds to a matching criterion found in the received set of mapped features. The sharable feature of the selected mapped feature is identified and sent to a privacy compliant destination. Advantageously, the analysis system protects the privacy of the mobile device user because it does not require the mobile device to relay protected information for the selection of customized content or relevant advertisements.

First claim

What is claimed is:

1. A computer-implemented method for feature analysis, the method comprising:
providing a plurality of mapped features to a mobile device, each mapped feature comprising an item of protected information mapped to a non-unique sharable feature; and
providing privacy compliance instructions to the mobile device for execution at the mobile device wherein the privacy compliance instructions comprise instructions for:
generating a score for at least one item of protected information available to the mobile device;
matching the at least one item of protected information available to the mobile device to a mapped feature from the provided plurality of mapped features, the matching mapped feature's item of protected information matching the item of protected information available to the mobile device; and
sending the matching mapped feature's generated score.

2. The method of claim 1 wherein the privacy compliance instructions further comprise instructions for:
sending the matching mapped feature's non-unique sharable feature.

3. The method of claim 1 further comprising:
sending an identifier.

4. The method of claim 1 wherein:
generating the score comprises generating a collective score characterizing at least two items of protected information available to the mobile device.

5. The method of claim 1 wherein:
the generated score comprises a category.

6. The method of claim 1 wherein:
the generated score comprises a range.

7. The method of claim 1 further comprising:
receiving the matching mapped feature's score from the mobile device;
selecting content based on the matching mapped feature's score; and
sending the selected content to the mobile device.

8. The method of claim 1 further comprising:
receiving the matching mapped feature's score from the mobile device;
customizing content based on the matching mapped feature's score; and
sending the customized content to the mobile device.

9. The method of claim 1 wherein:
at least one mapped feature maps an item of protected information comprising a geographic location to a non-unique sharable feature which is not a geographic location.

10. The method of claim 1 wherein:
at least one item of protected information comprises a geographic location described in relative coordinates.

11. The method of claim 1 wherein:
the matching mapped feature is a result of a match between at least one item of protected information available to the mobile device and a mapped feature, the match selected from the group consisting of: an inexact match, an approximate match and a probabilistic match.

12. A non-transitory computer readable medium with computer executable instructions stored thereon executed by a processor to perform a method, the method comprising:
providing a plurality of mapped features to a mobile device, each mapped feature comprising an item of protected information mapped to a non-unique sharable feature; and
providing privacy compliance instructions to the mobile device for execution at the mobile device wherein the privacy compliance instructions comprise instructions for:
generating a score for at least one item of protected information available to the mobile device;
matching the at least one item of protected information available to the mobile device to a mapped feature from the provided plurality of mapped features, the matching mapped feature's item of protected information matching the item of protected information available to the mobile device; and
sending the matching mapped feature's generated score.

13. The medium of claim 12 wherein:
the generated score comprises a category.

14. The medium of claim 12 wherein:
the generated score comprises a range.

15. The medium of claim 12 , the method further comprising:
receiving the matching mapped feature's score from the mobile device;
selecting content based on the matching mapped feature's score; and
sending the selected content to the mobile device.

16. The medium of claim 12 , the method further comprising:
receiving the matching mapped feature's score from the mobile device;
customizing content based on the matching mapped feature's score; and
sending the customized content to the mobile device.

17. The medium of claim 12 wherein:
at least one mapped feature maps an item of protected information comprising a geographic location to a non-unique sharable feature which is not a geographic location.

18. The medium of claim 12 wherein:
at least one item of protected information comprises a geographic location described in relative coordinates.

19. The medium of claim 12 wherein:
the matching mapped feature is a result of a match between at least one item of protected information available to the mobile device and a mapped feature, the match selected from the group consisting of: an inexact match, an approximate match and a probabilistic match.

20. A system comprising:
a processor; and,
a non-transitory computer readable storage medium storing processor-executable computer program instructions, the instructions comprising instructions for:
providing a plurality of mapped features to a mobile device, each mapped feature comprising an item of protected information mapped to a non-unique sharable feature; and
providing privacy compliance instructions to the mobile device for execution at the mobile device wherein the privacy compliance instructions comprise instructions for:
generating a score for at least one item of protected information available to the mobile device;
matching the at least one item of protected information available to the mobile device to a mapped feature from the provided plurality of mapped features, the matching mapped feature's item of protected information matching the item of protected information available to the mobile device; and
sending the matching mapped feature's generated score.
