CA 2584121

Techniques, systems and methods relating to cryptographically secure revocable biometric signatures and identification computed with robust distance metrics are described. Various biometric cryptographically secure revocable transformation approaches are described that support a robust pseudo-distance computation in encoded form (such as seen in figure 4), thereby supporting confidence in verification, and which can provide for verification without identification.

Cette invention concerne des techniques, des systèmes et des procédés associés à des signatures biométriques révocables à sécurité cryptographique et à l'identification calculée à l'aide de mesures de distance robustes. Cette invention décrit diverses approches biométriques de transformation révocable à sécurité cryptographique qui supportent un calcul de pseudo-distance robuste sous forme codée, renforçant ainsi la fiabilité de la vérification, et qui peuvent permettre d'effectuer une vérification sans identification.
