Abstract

A computing system includes: a control unit configured to: obtain an information release setting for a raw user information, the raw user information including an information attribute; determine an information format for the information attribute of the raw user information; determine a privacy notion based on the information release setting; generate perturbed user information from the information attribute based on the privacy notion, wherein the information format for the raw user information is preserved in the perturbed user information; and a communication unit, coupled to the control unit, configured to transmit the perturbed user information.

Claims

1. A computing system comprising:

a control unit configured to;

obtain an information release setting for a raw user information, the raw user information including an information attribute;

determine an information format for the information attribute of the raw user information;

determine a privacy notion based on the information release setting;

generate a perturbed user information from the information attribute based on the privacy notion, wherein the information format for the raw user information is preserved in the perturbed user information; and

a communication unit, coupled to the control unit, configured to transmit the perturbed user information.

2. The system as claimed in claim 1 further comprising a user interface, coupled to the control unit, configured to receive the information release setting including an attribute based privacy setting for the information attribute of the raw user information.

3. The system as claimed in claim 1 wherein the control unit is configured to generate the perturbed user information to resemble public information based on a public category factor.

4. The system as claimed in claim 1 wherein the control unit is configured to generate the perturbed user information based on an information utility notion for recommendation accuracy of the raw user information.

5. The system as claimed in claim 1 wherein the control unit is configured to generate the perturbed user information based on addition of admissible noise with a sensitivity factor.

6. The system as claimed in claim 1 wherein the control unit is configured to generate the perturbed user information from admissible noise based on an augmented Lagrange function.

7. The system as claimed in claim 1 wherein the control unit is configured to generate noise adjusted information from the raw user information based on an information category aggregate of the information attribute.

8. The system as claimed in claim 1 wherein the control unit is configured to preserve the information format of the raw user information including modifying the information attribute.

9. The system as claimed in claim 1 wherein the control unit is configured to generate the perturbed user information based on a differential privacy function.

10. The system as claimed in claim 1 further comprising a user interface, coupled to the control unit, configured to receive the information release setting for the raw user information.

11. A method of operation of a computing system comprising:

obtaining an information release setting for a raw user information, the raw user information including an information attribute;

determining an information format for the information attribute of the raw user information;

determining a privacy notion based on the information release setting;

generating a perturbed user information from the information attribute based on the privacy notion, wherein the information format for the raw user information is preserved in the perturbed user information.

12. The method as claimed in claim 11 wherein obtaining the information release setting includes receiving an attribute based privacy setting for the information attribute of the raw user information.

13. The method as claimed in claim 11 wherein generating the perturbed user information includes generating the perturbed user information to resemble public information based on a public category factor.

14. The method as claimed in claim 11 wherein generating the perturbed user information includes generating the perturbed user information based on an information utility notion for recommendation accuracy of the raw user information.

15. The method as claimed in claim 11 wherein generating the perturbed user information includes generating the perturbed user information based on addition of admissible noise with a sensitivity factor.

16. A non-transitory computer readable medium including instructions executable by a control circuit for a computing system, the instructions comprising:

obtaining an information release setting for a raw user information, the raw user information including an information attribute;

determining an information format for the information attribute of the raw user information;

determining a privacy notion based on the information release setting;

generating a perturbed user information from the information attribute based on the privacy notion, wherein the information format for the raw user information is preserved in the perturbed user information.

17. The non-transitory computer readable medium as claimed in claim 16 wherein obtaining the information release setting includes receiving an attribute based privacy setting for the information attribute of the raw user information.

18. The non-transitory computer readable medium as claimed in claim 16 wherein generating the perturbed user information to resemble public information based on a public category factor.

19. The non-transitory computer readable medium as claimed in claim 16 wherein generating the perturbed user information includes generating the perturbed user information based on an information utility notion for recommendation accuracy of the raw user information.
