Title: Device for identifying a person, especially by fingerprint detection
Inventor: JEAN-PIERRE GLOTON
IPC: G07C9/00
Filed: 1991-03-14
Abstract: The invention relates to devices which allow the automatic identification of persons, in particular by their fingerprints. It consists in using as sensitive element a thin layer (101) of a piezoelectric material. The ridges and hollows of the print exert different pressures on the film and therefore generate different voltages. A characteristic signal of the print is obtained, which can optionally be used to modulate the signal from a microwave or ultrasound beam scanning the film. Means of comparison (103) make it possible to compare this signal with previously recorded signals to effect identification. It allows the reliable and rapid identification of persons.
