Abstract
The present invention concerns a method and device for detecting the orientation of an area (DO) of the body of an individual placed on an apposition area (AP) of a biometric sensor mounting (P) designed to form a first image (I1) of the area (DO) of the body by total reflection of radiation on the apposition area (AP), and a second image (I2) of the area (DO) of the body from radiation able to pass through the tissues of the body and to be reflected on haemoglobin. The method is characterized in that it comprises The present invention also concerns a biometric sensor and an installation for identifying an individual comprising such a device.
