Title: Collating system of person himself
Inventor: HOSHINO YUKIO
IPC: G06F21/32
Filed: 1984-04-18
Abstract: PURPOSE:To identify a person himself by collating feature points, etc., of a fingerprint due to microcomputer processing through use of only picture data readout by straight line scanning with respect to a fingerprint pattern on the picture. CONSTITUTION:A fingerprint input device 11 generates a photoelectric transfer picture of a fingerprint pattern by means of a light source and an image pickup device such as an ITV by utilizing optical boundary conditions of glass from the reverse surface with respect to a finger placed on a glass plate. The picture signal is A/D converted 12 and stored in a memory 13, while information regarding feature points and the relation between them on a minutiae card readout by a card reader 15 is held in a working memory 103 of a collating device 10, which properly matches a fingerprint picture stored in the memory 13 to the feature point group and the relation between feature points readout from the minutiae card. The successful matching and unsuccessful matching are decided to be coincident and dissident, respectively.

The input given from line 1 and the output of line 2 have different formats to each other since they were processed at circuit A-1. Device A-2 applies the parity code for correction to the input code to then send it to the transmitter comprising transmitter T and the antenna as well as to antenna A-3 via line 3. Then A-3 transmits the digital signals encoded at A-2 via the radio circuit 4. For circuit 4, the transmission signals are received at station B from station A. And B-3 consists of the antenna and the receiver, and the output obtained by demodulating the received signals is supplied to receiving error correction device B-2(EPR) via line 5. Thus the error correction is carried out with every character via the information and the parity code.
