METHOD OF DETECTING BIOLOGICAL PATTERN, BIOLOGICAL PATTERN DETECTOR, METHOD OF BIOLOGICAL CERTIFICATE AND BIOLOGICAL CERTIFICATE APPARATUS

摘要

Solve the problems, such as: To allows the risk in impermanent biometrics forgery, and allows biological attribute to identify, while and bioassay. ;SOLUTION: the distribution deep layer consecutive skin barrier of groove/land extracts pattern by epidermal tissue and reads unique living body. The biometrics is executed based on the pattern read. Read the groove/protrusion distribution pattern deep skin organism optical execute using differential optical characteristic in epidermal tissue with deep tissues skin. At this point, the light of long wavelength, such as light near infrared frequency band are used as irradiation light and irradiate epidermal tissue. Detected position is set as such as branched fraction blood vessel at heart with the branched fraction of determination position to be detected and shape at this point, biological attribute mark can be carried out at heart using the blood vessel. ;COPYRIGHT:(C) 2004, JPO
