Abstract

Methods, systems, and products authenticate users for access to devices, applications, and services. Skills of a user are learned over time, such that an electronic model of random subject matter may be generated. The user is prompted to interpret the random subject matter, such as with a drawing, physical arrangement, or performance. The user'"'"'s interpretation is then compared to the electronic model of the random subject matter. If the user is truly who they purport to be, their interpretation will match the electronic model, thus authenticating the user. If interpretation fails to match the electronic model, authentication may be denied.

Claims

1. A method, comprising:

retrieving, at a server, randomly selected subject matter;

sending, from the server, the randomly selected subject matter to a client device for authentication of a user;

receiving, at the server, data describing a sketch of the randomly selected subject matter drawn by the user; and

authenticating, by the server, the user based on the sketch of the randomly selected subject matter.

2. The method of claim 1, further comprising sending a query for the randomly selected subject matter.

3. The method of claim 1, further comprising retrieving sketching skills associated with the user of the client device.

4. The method of claim 3, further comprising generating a freehand model of the randomly selected subject matter using the sketching skills.

5. The method of claim 3, further comprising generating a prediction of the randomly selected subject matter using the sketching skills.

6. The method of claim 3, further comprising learning the sketching skills associated with the user of the client device.

7. The method of claim 3, further comprising repeating a prompt-and-sketch routine to learn the sketching skills associated with the user of the client device.

8. The method of claim 1, further comprising retrieving an entry from a listing of nouns as the randomly selected subject matter.

9. A system, comprising:

a processor; and

a memory storing instructions that, when executed by the processor, cause the processor to perform operations, the operations comprising;

randomly selecting subject matter from a database of subject matter;

sending the subject matter to a client device for authentication of a user;

receiving data describing a sketch of the subject matter drawn by the user; and

authenticating the user based on the sketch of the subject matter.

10. The system of claim 9, wherein the operations further comprise querying for the random subject matter.

11. The system of claim 9, wherein the operations further comprise retrieving sketching skills associated with the user of the client device.

12. The system of claim 11, wherein the operations further comprise generating a freehand model of the subject matter using the sketching skills.

13. The system of claim 11, wherein the operations further comprise generating a prediction of the subject matter using the sketching skills.

14. The system of claim 11, wherein the operations further comprise learning the sketching skills associated with the user of the client device.

15. The system of claim 9, wherein the operations further comprise randomly selecting the subject matter from a listing of nouns.

16. The system of claim 11, wherein the operations further comprise rejecting the subject matter as too complicated for the sketching skills of the user.

17. The system of claim 9, wherein the operations further comprise receiving touch screen data describing the sketch of the subject matter inputted on a touch screen of the client device.

18. A memory storing instructions that when executed cause a processor to perform operations, the operations comprising:

retrieving randomly selected subject matter from a database;

sending the randomly selected subject matter to a client device for authentication of a user;

receiving data describing a sketch of the randomly selected subject matter drawn by the user; and

authenticating the user based on the sketch of the randomly selected subject matter.

19. The memory of claim 18, wherein the operations further comprise generating a prediction of the randomly selected subject matter.

20. The memory of claim 19, wherein the operations further comprise comparing the sketch to the prediction.
