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 method, comprising:
accessing, by a mobile application of a mobile device, a first set of mapped features comprising a plurality of items of protected information, each item of protected information mapped to at least one non-unique sharable feature;
accessing, by the mobile application, a first item of protected information of the plurality of items of protected information;
selecting, by the mobile application, a first non-unique sharable feature from the at least one non-unique shareable features mapped to the first item of protected information; and
providing, by the mobile application, the first non-unique sharable feature.

2. The method of claim 1 , further comprising:
accessing, by the mobile application, a second set of mapped features comprising the plurality of items of protected information, the first item of protected information mapped to at least one new non-unique sharable feature that was not in the first set of mapped features;
selecting, by the mobile application, a new non-unique sharable feature from the at least one new non-unique shareable features mapped to the first item of protected information; and
providing, by the mobile application, the new non-unique sharable feature.

3. The method of claim 2 , wherein the second set of mapped features corresponds to the first non-unique sharable feature.

4. The method of claim 2 , wherein the second set of mapped features corresponds to an advertising campaign.

5. The method of claim 2 , wherein no combination of the non-unique sharable features corresponding to the first item of protected information in the first set of mapped features and the new non-unique sharable features corresponding to the first item of protected information in the second set of mapped features is unique to the first item of protected information.

6. The method of claim 2 , wherein accessing, by the mobile application, the second set of mapped features is responsive to a change in a location of the mobile device.

7. The method of claim 2 , wherein accessing, by the mobile application, the second set of mapped features is responsive to a change in a time-dependent aspect of the first item of protected information.

8. A non-transitory computer-readable storage medium storing processor-executable computer program instructions that, when executed, cause a computer processor to perform a method, the method comprising:
accessing, by a mobile application of a mobile device, a first set of mapped features comprising a plurality of items of protected information, each item of protected information mapped to at least one non-unique sharable feature;
accessing, by the mobile application, a first item of protected information of the plurality of items of protected information;
selecting, by the mobile application, a first non-unique sharable feature from the at least one non-unique shareable features mapped to the first item of protected information; and
providing, by the mobile application, the first non-unique sharable feature.

9. The medium of claim 8 , further comprising:
accessing, by the mobile application, a second set of mapped features comprising the plurality of items of protected information, the first item of protected information mapped to at least one new non-unique sharable feature that was not in the first set of mapped features;
selecting, by the mobile application, a new non-unique sharable feature from the at least one new non-unique shareable features mapped to the first item of protected information; and
providing, by the mobile application, the new non-unique sharable feature.

10. The medium of claim 9 , wherein the second set of mapped features corresponds to the first non-unique sharable feature.

11. The medium of claim 9 , wherein the second set of mapped features corresponds to an advertising campaign.

12. The medium of claim 9 , wherein no combination of the non-unique sharable features corresponding to the first item of protected information in the first set of mapped features and the new non-unique sharable features corresponding to the first item of protected information in the second set of mapped features is unique to the first item of protected information.

13. The medium of claim 9 , wherein accessing, by the mobile application, the second set of mapped features is responsive to a change in a location of the mobile device.

14. The medium of claim 9 , wherein accessing, by the mobile application, the second set of mapped features is responsive to a change in a time-dependent aspect of the first item of protected information.

15. A system comprising:
a processor; and
a non-transitory computer-readable storage medium storing processor-executable computer program instructions that, when executed, cause a computer processor to perform a method, the method comprising:
accessing, by a mobile application of a mobile device, a first set of mapped features comprising a plurality of items of protected information, each item of protected information mapped to at least one non-unique sharable feature;
accessing, by the mobile application, a first item of protected information of the plurality of items of protected information;
selecting, by the mobile application, a first non-unique sharable feature from the at least one non-unique shareable features mapped to the first item of protected information; and
providing, by the mobile application, the first non-unique sharable feature.

16. The system of claim 15 , further comprising:
accessing, by the mobile application, a second set of mapped features comprising the plurality of items of protected information, the first item of protected information mapped to at least one new non-unique sharable feature that was not in the first set of mapped features;
selecting, by the mobile application, a new non-unique sharable feature from the at least one new non-unique shareable features mapped to the first item of protected information; and
providing, by the mobile application, the new non-unique sharable feature.

17. The system of claim 16 , wherein the second set of mapped features corresponds to the first non-unique sharable feature.

18. The system of claim 16 , wherein the second set of mapped features corresponds to an advertising campaign.

19. The system of claim 16 , wherein no combination of the non-unique sharable features corresponding to the first item of protected information in the first set of mapped features and the new non-unique sharable features corresponding to the first item of protected information in the second set of mapped features is unique to the first item of protected information.

20. The system of claim 16 , wherein accessing, by the mobile application, the second set of mapped features is responsive to a change in a location of the mobile device.

21. The system of claim 16 , wherein accessing, by the mobile application, the second set of mapped features is responsive to a change in a time-dependent aspect of the first item of protected information.
