A device, system and method for identifying an individual with a biometric identifier that is designed to be non-unique, such that at least one other individual in a given population has the identical biometric identifier. The biometric identifier according to the present invention, also referred to herein as a "BIdToken", is implemented to be biometrically traceless, such that an exact image or copy of the biometric information is preferably not maintained by the present invention. Instead, the BIdToken refers to an incomplete identifier obtained from the biometric information, which is non-unique. Preferably the invention operates so as to obviate the obligation to trust a third party.

L'invention concerne un dispositif, un système et un procédé d'identification d'un individu avec un identifiant biométrique qui est mis au point pour être non unique, de telle sorte qu'au moins un autre individu dans une population donnée possède l'identifiant biométrique identique. L'identifiant biométrique, conformément à la présente invention, également appelé ici un <= BIdToken >= (jeton d'identifiant biométrique), est implémenté pour être biométriquement sans trace, de telle sorte qu'une image ou une copie exacte des informations biométriques n'est de préférence pas maintenue par la présente invention. À la place, le BIdToken concerne un identifiant incomplet obtenu à partir des informations biométriques, qui sont non uniques. De préférence, l'invention est employée de manière à éviter l'obligation de se fier à un tiers.
