Abstract

A method is used in using spatial diversity with secrets. A spatially diverse presentation is presented. A reaction of a user to the spatially diverse presentation is received and analyzed. The analysis is used as a basis for helping to determine whether the user has knowledge of a secret.

Claims

1. A computer-implemented method, comprising:

presenting, by a device, a spatially diverse presentation comprising images at different viewing angles, wherein the images comprise an image based on a secret at a viewing angle;

receiving a reaction of a user to the spatially diverse presentation, wherein the reaction comprises information relating to the movement of the device by the user between a starting position and a viewing position;

performing an analysis of the reaction of the user to the spatially diverse presentation, wherein the analysis determines an angle between the starting position and the viewing position; and

based on the analysis, helping to determine whether the user has knowledge of the secret.

2. The method of claim 1, wherein the analysis may be used to allow a user to prove knowledge of a secret password.

3. The method of claim 1, wherein the spatially diverse presentation is provided by a handheld electronic device.

4. The method of claim 1, wherein the spatially diverse presentation is provided by a small form factor 3-dimensional display.

5. The method of claim 1, wherein the spatially diverse presentation is used in a challenge-response protocol.

6. The method of claim 1, wherein the spatially diverse presentation comprises simultaneously presenting different images at different respective angles.

7. The method of claim 1, wherein the spatially diverse presentation is derived from a secret.

8. The method of claim 1, wherein the analysis is based on detection of a change in position of at least a portion of a device displaying the spatially diverse presentation.

9. A system, comprising:

a processor and memory;

the system configured to;

present, by a device, a spatially diverse presentation comprising images at different viewing angles, wherein the images comprise an image based on a secret at a viewing angle;

receive a reaction of a user to the spatially diverse presentation, wherein the reaction comprises information relating to the movement of the device by the user between a starting position and a viewing position;

perform an analysis of the reaction of the user to the spatially diverse presentation, wherein the analysis determines an angle between the starting position and the viewing position; and

based on the analysis, help to determine whether the user has knowledge of the secret.

10. The system of claim 9, wherein the analysis may be used to allow a user to prove knowledge of a secret password.

11. The system of claim 9, wherein the spatially diverse presentation is provided by a handheld electronic device.

12. The system of claim 9, wherein the spatially diverse presentation is provided by a small form factor 3-dimensional display.

13. The system of claim 9, wherein the spatially diverse presentation is used in a challenge-response protocol.

14. The system of claim 9, wherein the spatially diverse presentation comprises simultaneously presenting different images at different respective angles.

15. The system of claim 9, wherein the spatially diverse presentation is derived from a secret.

16. The system of claim 9, wherein the analysis is based on detection of a change in position of at least a portion of a device displaying the spatially diverse presentation.
