  • Fingerprint identification device equipped with a user recording unit
    Patent number: 6959105
    Abstract: A fingerprint identification device to identify fingerprints is equipped with a fingerprint reader unit to input a fingerprint to be detected and a database unit to record a fingerprint database which is provided in advance. A fingerprint comparing unit identifies the input fingerprint via the fingerprint reader unit by comparing with the fingerprint database recorded in the database unit and a user recording unit records the input fingerprint input by the fingerprint reader unit.

  • Fingerprint identification device-equip with a touch sensor for detecting a human finger
    Patent number: 6647133
    Abstract: A fingerprint identification device judges that the input fingerprint is identical to the fingerprint in the database only when a the touch sensor detects the human finger and a the fingerprint processing unit detects that the input fingerprint is identical to a fingerprint in the database. The touch sensor includes an oscillator that outputs a high frequency signal. An electrode unit applies the high frequency signal to the human finger. A detector unit detects a variation of impedance values varied by the human finger contracting the electrode unit and outputs an output signal based on the variation of impedance values. A discriminator unit determines whether the human finger is in contact with the electrode unit by comparing the output signal from the detector unit with a predetermined reference value.
