Abstract

A system for biometrically authenticating a user includes:

• • elements for obtaining image data that are representative of at least one user-associated biometric feature and at least one user-associated identifier,
  • elements for extracting the at least one biometric feature in the image data,
  • elements for extracting the at least one identifier in the image data,
  • elements for performing a search for a reference biometric feature associated with the at least one identifier,
  • elements for comparing the extracted biometric feature with the reference biometric feature, and
  • elements for authenticating the user in accordance with a result of the comparison.

Claims

1. A system for biometrically authenticating a user, comprising:

means for obtaining image data that are representative of at least one user-associated biometric feature and at least one user-associated identifier,

means for extracting said at least one biometric feature in said image data,

means for extracting said at least one identifier in said image data,

means for performing a search for a reference biometric feature associated with said at least one identifier,

means for comparing said extracted biometric feature with said reference biometric feature, and

means for authenticating said user in accordance with a result of said comparison.

2. The system according to claim 1, wherein said image data belongs to the same image.

3. The system according to claim 1, wherein said image data is distributed between at least two images representing said biometric feature and said identifier, respectively.

4. The system according to claim 1, further comprising a single image data acquisition unit for acquiring said image data.

5. The system according to claim 4 in combination, wherein said image data acquisition unit is an optical unit, configured for:

acquiring a first image at at least one first wavelength, and

acquiring a second image at at least one second wavelength different from said at least one first wavelength.

6. The system according to claim 3, further comprising at least two image data acquisition units for acquiring said image data.

7. The system according to claim 6, comprising:

means for acquiring a first image which is representative of said biometric feature using a first image data acquisition unit, and

means for acquiring a second image which is representative of said identifier using a second image data acquisition unit different from the first image data acquisition unit.

8. The system according to claim 1, wherein said biometric feature is at least one of a user'"'"'s fingerprint, a user'"'"'s vein pattern and a user'"'"'s face.

9. The system according to claim 1, wherein said biometric feature is an iris of the user.

10. The system according to claim 1, wherein said identifier is imprinted onto a user'"'"'s skin portion using at least one of tattooing, engraving and depositing an adhesive carrier.

11. The system according to claim 1, wherein said identifier is imprinted onto a subcutaneous feature arranged beneath a skin feature of the user.

12. The system according to claim 1, wherein said identifier is imprinted onto an ophthalmic lens or a spectacle frame worn by the user.

13. The system according to claim 1, wherein said identifier comprises a link to a remote server.

14. The system according to claim 1, wherein said biometric feature and said identifier are superimposed.

15. The system according to claim 1, wherein said identifier is displayed on a screen of a user-associated portable electronic device.

16. The system according to claim 1, further comprising means for providing the user with a carrier for the identifier, said means comprising:

means for acquiring image data that are representative of the user-associated biometric feature,

means for generating the user-associated identifier,

means for storing said acquired data as the reference biometric feature and said identifier in a table which associates said acquired data with said identifier, and

means for imprinting said identifier into said carrier.

17. The system according to claim 15, wherein said imprinting means include at least one of:

means for tattooing the identifier onto a skin feature of the user,

means for engraving the identifier onto a skin feature of the user,

means for printing said identifier onto an adhesive carrier and gluing said carrier on a skin feature of the user,

means for storing said identifier in a portable electronic device which is configured to display said identifier and is associated with the user, and

means for engraving said identifier onto an ophthalmic lens or a spectacle frame associated with the user.

18. The system according to claim 1, further comprising at least one of an ophthalmic lens and a spectacle frame associated with the user, wherein said ophthalmic lens and said spectacle frame carry said user-associated identifier.

19. Method for biometrically authenticating a user, which includes the steps of:

obtaining image data that are representative of at least one user-associated biometric feature and at least one user-associated identifier,

extracting said at least one biometric feature in said image data,

extracting said at least one identifier in said image data,

performing a search for a reference biometric feature associated with said at least one identifier,

comparing said extracted biometric feature with said reference biometric feature, and

authenticating said user in accordance with a result of said comparison.

20. A computer program, comprising instructions for the implementation of a method according to claim 19 when it is loaded and executed by a processor of a system for biometrically authenticating a user.
