Biometric identification system based on venous networks and unique and non-falsifiable encodings of tree structures and associated method.

摘要

A non-nominative resilient biometric authentication system based on venous networks, comprising a light source, for illuminating a body part of a user, and a detection device (1), comprising a sensor (2 ) for capturing without contact a venous network of said user's body part, an extraction unit (3) of biometric characteristics, and a conversion unit (4) of the biometric characteristics, the detection device (1) having a unique identifier, the extraction unit (3) of biometric characteristics extracting a quantity of characteristics from the biometric information obtained by the sensor (2) and generating a vascular impression. The conversion unit (4) of the characteristics is able to convert said vascular impression, via an encoding algorithm, combining the identifier of the device with the extracted characteristics, into a variable numerical identifier, so that said numerical identifier is not not related to said user's vascular impression and is generated without any identification information of said user and in that said generated digital identifier is specific to said data detection device. The invention further relates to a biometric authentication method implemented using the system as well as uses relating to digital communication systems and the exchange of medical information.
