Abstract

In one embodiment, a picture signature password system may use a picture signature password to determine access to a computing device or service. A display screen 172 may display a personalized digital image 310. A user input device 160 may receive a user drawing set executed by a user over the personalized digital image 310. A processor 120 may authenticate access to the user session if the user drawing set matches a library drawing set associated with the user.

Claims

1. A machine-implemented method for authenticating a user session, comprising:

displaying a personalized digital image on a display screen;

receiving a user drawing set executed by a user over the personalized digital image;

associating a user drawing set member with a user position set;

associating a library drawing set member with a library position set; and

determining the user drawing set member and the library drawing set member match in part if the user position set is within a position tolerance value of the library position set; and

authenticating access to the user session if the user drawing set matches a library drawing set associated with the user.

2. The method of claim 1, further comprising:

tracing the user drawing set onto the personalized digital image.

3. The method of claim 1, wherein the user drawing set includes at least one of a user touch point, a user circle gesture, a user line gesture, and a user freestyle form gesture.

4. The method of claim 1, further comprising:

receiving an initial library drawing set input from the user; and

creating the library drawing set from the initial library drawing set input.

5. The method of claim 4, further comprising:

receiving a confirmation library drawing set input from the user; and

displaying a reentry request if the confirmation library drawing set input does not match the initial library drawing set input.

6. The method of claim 5, further comprising:

tracing a training library drawing set to the user if the confirmation library drawing set input does not match the initial library drawing set input.

7. The method of claim 1, further comprising:

requesting reentry of the user drawing set if the user drawing set does not match the library drawing set associated with the user.

8. The method of claim 1, further comprising:

requesting a text password if the user drawing set does not match the library drawing set associated with the user.

10. The method of claim 1, further comprising:

associating a user drawing set member with a user vector set;

associating a library drawing set member with a library vector set; and

determining the user drawing set member and the library drawing set member match in part if the user vector set is within a vector tolerance value of the library vector set.

11. The method of claim 10, further comprising:

adjusting the position tolerance value and the vector tolerance value based on at least one of user accuracy, a user profile, and a user setting.

12. The method of claim 1, further comprising:

associating a library drawing set member with a set of timing data indicating at least one of duration of entry and speed of entry.

13. The method of claim 1, further comprising:

determining that the user drawing set matches the library drawing set if a majority of user drawing set members matches a majority of library drawing set members.

14. The method of claim 1, further comprising:

determining that the user drawing set matches the library drawing set based on an aggregate comparison score.

9. (canceled)

15. A tangible machine-readable medium having a set of instructions detailing a method stored thereon that when executed by one or more processors cause the one or more processors to perform the method, the method comprising:

displaying a digital image on a display screen;

receiving from a user over the digital image on the display screen a user drawing set having at least one user gesture;

associating a user drawing set member with a user position set;

associating a library drawing set member with a library position set; and

determining the user drawing set member and the library drawing set member match in part if the user position set is within a position tolerance value of the library position set; and

authenticating access to a user session if the user drawing set matches a library drawing set associated with the user.

16. The tangible machine-readable medium of claim 15, wherein the user gesture is at least one of a user circle gesture, a user line gesture, and a user freestyle form gesture.

17. The tangible machine-readable medium of claim 15, wherein the method further comprises:

receiving the digital image from a personalized digital image library provided by the user.

18. The tangible machine-readable medium of claim 15, wherein the method further comprises:

setting a minimum library set size and a minimum complexity level for a library drawing set associated with the user.

19. A picture signature password system, comprising:

a display screen to display a personalized digital image;

a user input device to receive from a user over the digital image on the display screen a user drawing set having at least one user gesture; and

a processor to authenticate access to a user session if the user drawing set matches a library drawing set associated with the user by associating a user drawing set member with a user position set, associating a library drawing set member with a library position set, and determining the user drawing set member and the library drawing set member match in part if the user position set is within a position tolerance value of the library position set.

20. The picture signature password system of claim 19, wherein the user input device is at least one of an interactive stylus, a mouse, a direct motion input or a touch screen integrated into the display screen.
