Abstract

A method and system are provided. The method includes training for one or more secondary signatures of a user. The method further includes identifying one or more inherent expressions of the user as the one or more secondary signatures. The method also includes authenticating the user using a primary signature and at least one of the one or more secondary signatures. The one or more inherent expressions are unintended expressions performed by the user in relation to the user providing the primary signature.

Claims

1. A method, comprising:

training, by a processor, for one or more secondary signatures of a user;

identifying, by the processor, one or more inherent expressions of the user as the one or more secondary signatures;

authenticating, by the processor, the user using a primary signature and at least one of the one or more secondary signatures; and

unlocking, by the processor, a lock to permit the user access to a locked item responsive to an authentication of the user using the primary signature and one or more of the secondary signatures,

wherein the one or more inherent expressions are unintended expressions performed by the user in relation to the user providing the primary signature, and wherein each of the primary signature and the at least one of the one or more secondary signatures are used as separate identification factors in a multi-factor authentication of the user.

2. The method of claim 1, wherein the one or more inherent expressions comprise at least one of, one or more gestures by the user, one or more movements by the user, one or more sounds produced by the user, a heart rate of the user, a blood pressure reading of the user, and a brainwave of the user.

3. The method of claim 1, wherein the one or more inherent expressions are performed by the user concurrently with the user providing the primary signature.

4. The method of claim 1, wherein said training step comprises identifying the one or more inherent expressions over multiple primary signature providing sessions performed by the user.

5. The method of claim 1, wherein said training step comprises:

monitoring a user while a user is providing a primary signature a plurality of times to detect the one or more inherent expressions of the user;

performing an evaluation to evaluate the one or more inherent expressions of the user for certain criteria; and

storing, in a memory device, the one or more inherent expressions of the user as the one or more secondary signatures of the user based on a result of the evaluation.

6. The method of claim 5, wherein the certain criteria comprises one or more of a similarity and a probability of reoccurrence.

7. The method of claim 5, wherein said training step is repeatedly performed to update the one or more inherent expressions for use as the one or more secondary signatures.

8. The method of claim 5, wherein said training step is repeatedly performed to replace at least one of the one or more inherent expressions with at least another inherent expression as at least one of the one or more secondary signatures.

9. The method of claim 1, wherein said training step comprises modeling the one or more inherent expressions.

10. The method of claim 1, further comprising performing a physical action by a machine or device responsive to an authentication of the user using the primary signature and one or more of the secondary signatures.

11. A non-transitory article of manufacture tangibly embodying a computer readable program which when executed causes a computer having the processor to perform the steps of claim 1.

12. A system, comprising:

a hardware processor configured to;

train for one or more secondary signatures of a user;

identify one or more inherent expressions of the user as the one or more secondary signatures;

authenticate the user using a primary signature and at least one of the one or more secondary signatures; and

unlock a lock to permit the user access to a locked item responsive to an authentication of the user using the primary signature and one or more of the secondary signatures,

wherein the one or more inherent expressions are unintended expressions performed by the user in relation to the user providing the primary signature, and wherein each of the primary signature and the at least one of the one or more secondary signatures are used as separate identification factors in a multi-factor authentication of the user.

13. The system of claim 12, wherein the one or more inherent expressions comprise at least one of, one or more gestures by the user, one or more movements by the user, one or more sounds produced by the user, a heart rate of the user, a blood pressure reading of the user, and a brainwave of the user.

14. The system of claim 12, wherein the one or more inherent expressions are performed by the user concurrently with the user providing the primary signature.

15. The system of claim 12, wherein the one or more inherent expressions are performed by the user before or after, and in relation to, the user providing the primary signature.

16. The system of claim 12, further comprising a memory device, and wherein said hardware processor monitors a user while a user is providing a primary signature a plurality of times to detect the one or more inherent expressions of the user, performs an evaluation to evaluate the one or more inherent expressions of the user for certain criteria, and accepts the one or more inherent expressions of the user as the one or more secondary signatures of the user based on a result of the evaluation.

17. The system of claim 16, wherein the certain criteria comprises one or more of a similarity and a probability of reoccurrence.

18. The system of claim 16, wherein said hardware processor updates the one or more inherent expressions for use as the one or more secondary signatures.

19. The system of claim 16, wherein said hardware processor replaces at least one of the one or more inherent expressions with at least another inherent expression as at least one of the one or more secondary signatures.

20. The system of claim 12, wherein at least part of the at least of the one or more secondary signatures is different from another part of the at least one of the one or more secondary signatures, and a timing of the at least part of the at least one of the one or more secondary signatures is correlated by the hardware processor to a timing of at least part of the primary signature in order to authenticate the user.
