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, comprising a sensor for capturing without contact a venous network of said body part of the user, a extraction unit of biometric characteristics, and a conversion unit of biometric characteristics, the detection device having a unique identifier, the extraction unit of biometric characteristics extracting a quantity of characteristics from the biometric information obtained by the sensor and generating a vascular fingerprint, characterized in that the conversion unit of characteristics being able to convert said vascular fingerprint, via a coding algorithm combining the identifier of the device with the extracted characteristics, in a numerical variable identifier, such that said numerical identifier is not related to said user's vascular fingerprint and is generated without any identification information of said user and said generated numerical identifier is specific to said detection device data. The system further comprises a first server that operates in a client/server environment with the detection device and a second server that includes a code conversion unit and a correspondence determination unit. The invention further relates to the method implemented in the system and its use.
