Abstract

Surfaces for information security and protection of physical biometrics, such as a fingerprint, is described. Such biometric information recording surface includes a plurality of raised structures that can reproduce a biometric information when a body part containing the biometric information is applied to the biometric metric information recording surface. The reproduced biometric information can be completely removed by applying a liquid to the plurality of raised structures without need to apply an external physical contact.

First claim

What is claimed is:

1. A method of removing imprinted biometrics information from surfaces comprising:
providing a biometric information recording surface comprising a plurality of raised structures,
reproducing a biometric information on the plurality of raised structures by applying a pressure from a part of a body containing the biometric information to the biometric information recording surface, and
removing the biometric information by applying a liquid to the plurality of raised structures without a need of applying an external physical contact.

2. The method of claim 1 , wherein the plurality of raised structures are clustered.

3. The method of claim 1 , wherein the plurality of raised structures comprise a polymer.

4. The method of claim 1 , wherein the plurality of raised structures comprise polydimethylsiloxane or polypropylene.

5. The method of claim 1 , wherein the biometric information is recorded after reproduction.

6. The method of claim 1 , wherein the liquid is a disinfecting liquid.

7. The method of claim 2 , wherein said applying a liquid includes wicking the liquid between the plurality of raised structures to form unclustered plurality of raised structures.

8. The method of claim 1 , wherein said removing the biometric information includes drying the liquid to form randomly clustered plurality of raised structures.

9. The method of claim 1 , wherein biometric information recording surface is provided on an optical reader.

10. The method of claim 9 , wherein the optical reader is transparent.

11. The method of claim 1 , wherein the biometric information is a fingerprint.

12. The method of claim 11 , wherein the biometric information recording surface is a surface of a fingerprint reader in high-traffic security area.

13. The method of claim 1 , wherein the biometric information according surface is a surface of a personal number identification pad.

14. The method of claim 1 , wherein the biometric information recording surface is a surface of a safe.

15. The method of claim 1 , wherein the biometric information recording surface is a surface of a car door lock.

16. The method of claim 1 , wherein the biometric information recording surface is a surface of a touch screen device.

17. A biometric information identification device, comprising:
a biometric information reading optical reader;
a biometric information recording surface comprising a plurality of raised structures that is capable of reproducing a biometric information on the plurality of raised structures by application of a pressure from a part of a body containing the biometric information to the biometric information recording surface; and
a liquid that is capable of removing the biometric information by applying the liquid to the plurality of raised structures without a need of applying an external physical contact.

18. The biometric information identification device of claim 17 , wherein the plurality of raised structures are clustered.

19. The biometric information identification device of claim 17 , wherein the plurality of raised structures comprise a polymer.

20. The biometric information identification device of claim 17 , wherein the plurality of raised structures comprise polydimethylsiloxane or polypropylene.

21. The biometric information identification device of claim 17 , further comprising a storage device to record the biometric information after reproduction.

22. The biometric information identification device of claim 17 , wherein the liquid is a disinfecting liquid.

23. The biometric information identification device of claim 17 , wherein the optical reader is transparent.

24. The biometric information identification device of claim 17 , wherein the biometric information is a fingerprint.

25. The biometric information identification device of claim 24 , wherein the device is a fingerprint reader in a high-traffic security area.

26. The biometric information identification device of claim 17 , wherein the device includes a personal number identification pad.

27. The biometric information identification device of claim 17 , wherein the device is a safe.

28. The biometric information identification device of claim 17 , wherein the device includes a car door lock.

29. The biometric identification device of claim 17 , wherein the device is a touch screen device.
