Abstract

PURPOSE: To secure the fingerprint identification in a short time and only in the course of dry process as well as facilitate the secret keeping, by writing the fingerprint pattern into the picture converting element for temporary memorization and then writing the holographic filter image for identification and in piling onto the converting element.
CONSTITUTION: The following units are provided: central unit 25 which files the system for fingerprint identification; plural units of fingerprint identifier terminal 27; and plural units of unit 26 exclusive for registering each. In such constitution, terminal 27 consists of fingerprint writing part 28, control part 29, transmission control part 30, keyboard 31 and facilities door control alarm generating part 32 each. At the same time, hologram filing part 33 is provided to unit 26 in addition to part 28 and board 31 with the mutual connection secured among these units. Part 28 comprises He-Ne laser 40, shutters 41 and 43, object lens 42, illumination light source 44, half-mirror 45, pinhole 46, erasing light source 47, polarizer 48, picture converting element 49, photodetector 50, and image forming lens 51 each. Thus the fingerprint pattern is written onto element 49.
