Personal authentication device and method of manufacturing such a device
View Patent ↗The invention relates to an authentication device ( 1 ), characterized in that it comprises a support ( 10 ) provided with a surface ( 12 ), said surface comprising a plurality of peaks ( 14 ) and valleys ( 15 ) forming a pattern ( 13 ) capable of being acquired by a digital fingerprint sensor. The invention also relates to a method of manufacturing such a device.
1. A personal authentication device for the authentication or identification of an individual on a system having a digital fingerprint sensor, the device comprising:
a support provided with a surface, said surface having a plurality of peaks and valleys forming a pattern configured to be read by the digital fingerprint sensor to authenticate or identify the individual.
2. The personal authentication device according to claim 1 , wherein the pattern formed by the peaks and the valleys is arranged so as not to correspond to a human digital fingerprint.
3. The personal authentication device according to claim 1 , wherein the arrangement of peaks and valleys in the pattern is randomly generated.
4. The personal authentication device according to claim 2 , wherein the pattern formed by the peaks and the valleys includes at least two cores.
5. The personal authentication device according to claim 1 , wherein the support is made of a supple or rigid material.
6. The personal authentication device according to claim 1 , said support being one of a card, a key ring, a ring, and an earring.
7. A method of manufacturing a device, comprising:
generating, on a surface of a support, a set of valleys and peaks forming a pattern configured to be read by a digital fingerprint sensor to authenticate or identify an individual.
8. The method of manufacturing according to claim 7 , further comprising:
working out, prior to the generating, a pattern such that said pattern does not correspond to a human digital fingerprint.
9. The method of manufacturing according to claim 7 , wherein the generating of the pattern on the support is carried out by etching or embedding of part of the surface of the support corresponding to the valleys of the pattern.
10. A method for authenticating an individual, comprising:
acquiring, via a digital fingerprint sensor, a pattern formed on a surface of a personal authentication or identification device, the surface being provided on a support and having a plurality of peaks and valleys;
comparing the pattern with at least one other pattern; and
performing authentication or identification based on the results of the comparing.
