Adaptive device for biometric authentication using ultrasound, infrared and contrast visible light photographs, without disclosure, via a decentralised computer network

摘要

The invention relates to a biometric authentication device, comprising:a positioning module with measurement zone;a cryptographic calculation module;ultrasound module;a module for measuring heart rate and blood pressure;a photographic module configured to create a photograph of the venous network of the finger;a photograph of the fingerprint of the finger;a contrast light spectrometry of the finger;and a photograph of the venous network of the finger by infrared which would capture the intrinsic emission of the finger.;The cryptographic module is configured to authenticate the user according to the vector image relating to said ultrasound of the venous and nervous networks of said finger, the measurement of a heart rate and the measurement of a blood pressure, the photograph of the venous network of said finger, the photograph of the fingerprint of said finger, and the spectrometry of said finger.
