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.

Claims

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;

responsive to a trigger, detecting an available item of protected information available to the mobile device;

selecting a non-unique sharable feature from the plurality of mapped features that maps to the detected available item of protected information; and

sending the non-unique sharable feature.

2. The method of claim 1, wherein:

the trigger comprises detecting a change in a state of the mobile device.

3. The method of claim 1, wherein:

the trigger comprises detecting a change in a state of a mobile application.

4. The method of claim 1, wherein:

the trigger comprises receiving a signal at the mobile device.

5. The method of claim 1, wherein:

the trigger operates according to a schedule.

6. The method of claim 1, further comprising:

sending an identifier.

7. The method of claim 1, further comprising:

receiving the non-unique sharable feature from the mobile device;

selecting content according to the non-unique sharable feature; and

sending the selected content to the mobile device.

8. The method of claim 1, further comprising:

receiving the non-unique sharable feature from the mobile device;

customizing content according to the non-unique sharable feature; and

sending the customized content to the mobile device.

9. 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;

responsive to a trigger, detecting an available item of protected information available to the mobile device;

selecting a non-unique sharable feature from the plurality of mapped features that maps to the detected available item of protected information; and

sending the non-unique sharable feature.

10. The medium of claim 9, wherein:

the trigger comprises detecting a change in a state of the mobile device.

11. The medium of claim 9, wherein:

the trigger comprises detecting a change in a state of a mobile application.

12. The medium of claim 9, wherein:

the trigger comprises receiving a signal at the mobile device.

13. The medium of claim 9, wherein:

the trigger operates according to a schedule.

14. The medium of claim 9, wherein the method further comprises:

sending an identifier.

15. The medium of claim 9, wherein the method further comprises:

receiving the non-unique sharable feature from the mobile device;

selecting content according to the non-unique sharable feature; and

sending the selected content to the mobile device.

16. 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;

responsive to a trigger, detecting an available item of protected information available to the mobile device;

selecting a non-unique sharable feature from the plurality of mapped features that maps to the detected available item of protected information; and

sending the non-unique sharable feature.

17. The system of claim 16, wherein:

the trigger comprises detecting a change in a state of the mobile device.

18. The system of claim 16, wherein:

the trigger comprises detecting a change in a state of a mobile application.

19. The system of claim 16, wherein:

the trigger comprises receiving a signal at the mobile device.

20. The system of claim 16, wherein the instructions further comprise instructions for:

receiving the non-unique sharable feature from the mobile device;

selecting content according to the non-unique sharable feature; and

sending the selected content to the mobile device.
