Abstract

Disclosed is a biosecure method and device for identifying a person. According to one embodiment of the present invention, said device comprises: a light source for directing a light beam to a part of the person'"'"'s body; a detector for measuring the light from the part of the person'"'"'s body and converting the light intensity into electrical signals of a spectrum; and a spectrum analyzer and comparator for analyzing the spectrum and comparing the spectrum with stored spectrum for the person. The present invention provides a biosecure system, which is simple, cost-effective and hard to be faked.

Claims

1. A biosecure method for identifying a person, comprising:

directing a light beam to a part of the person'"'"'s body;

analyzing a light spectrum generated therefrom; and

comparing analysis result of the spectrum with stored data for the person.

2. The biosecure method according to claim 1, wherein said spectrum comprises transmitted light spectrum.

3. The biosecure method according to claim 1, wherein said spectrum comprises scattered light spectrum.

4. The biosecure method according to claim 1, wherein said spectrum comprises changes with respect to time.

5. The biosecure method according to claim 1, wherein said spectrum comprises infrared spectrum.

6. The biosecure method according to claim 1, wherein said light beam is substantially a single-wavelength one.

7. The biosecure method according to claim 1, wherein said part of the person'"'"'s body is a finger of that person.

8. The biosecure method according to claim 1, further comprising the step of:

attaching an envelope to the part of the person'"'"'s body.

9. The biosecure method according to claim 1, further comprising the step of:

directing the light beam to another one part or a plurality of parts of the person'"'"'s body to generate additional light spectrum for subsequent analysis and comparison.

10. The biosecure method according to claim 9, wherein said step of directing the light beam are performed for a plurality of times and arranged in a particularly designed sequence.

11. The biosecure method according to claim 1, further comprising the step of:

updating the stored data by the analysis result, if the person is correctly identified.

12. A biosecure device for identifying a person, comprising:

a light source for directing a light beam to a part of the person'"'"'s body;

a detector for measuring the light from the part of the person'"'"'s body and converting the light intensity into electrical signals of a spectrum; and

a spectrum analyzer and comparator for analyzing the spectrum and comparing the spectrum with stored spectrum for the person.

13. The biosecure device according to claim 12, said light beam is substantially a single-wavelength one.

14. The biosecure device according to claim 12, wherein said light source comprises an LED.

15. The biosecure device according to claim 12, wherein said part of the person'"'"'s body is further attached with an envelope.

16. A personal electronic apparatus comprising the biosecure device according to claim 12.

17. The personal electronic apparatus according to claim 16, wherein the personal electronic apparatus is a telephone.

18. The personal electronic apparatus according to claim 16, wherein the personal electronic apparatus is a computer.

19. The biosecure device according to claim 12, wherein the biosecure device is designed in the way of lock-and-key.

20. The biosecure device according to claim 12, wherein said spectrum comprises changes with respect to time.

21. The biosecure device according to claim 20, wherein said changes are analyzed by way of frequency analysis.

22. The biosecure device according to claim 21, wherein said frequency analysis comprises harmonic analysis.
