  • Publication number: 20230098452
    Abstract: The present invention relates to a biometric and fingerprint recognition sensor structure and an electronic card using the same. The present invention discloses a biometric and fingerprint recognition sensor structure comprising: a fingerprint sensing electrode array comprising a plurality of fingerprint sensing electrodes and a biometric authentication electrodes formed to be electrically spaced apart along the outer edge of the fingerprint sensing electrode array. Conventionally, the electrode for biometric authentication has to be formed through a separate process from the fingerprint sensing electrode, but the biometric and fingerprint recognition sensor structure and the electronic card using the same according to the present invention can be formed through the same process as the fingerprint sensing electrode according to an appropriate design.

  • Patent number: 10621323
    Abstract: The present invention relates to a biometric authentication apparatus and a biometric authentication method. In the present invention, provided is the authentication apparatus and authentication method of, while placing an object for biometric authentication on a space between a first electrode and a second electrode, applying a square wave with a single period to the first electrode and performing biometric authentication using a measurement voltage width, which is a difference between a maximum value (a maximum measurement voltage value) and a minimum value (a minimum measurement voltage value) of voltage measured at the first electrode, and an arriving time required for the voltage measured at the first electrode to reach a particular range of the maximum measurement voltage value from the minimum measurement voltage value. The biometric authentication apparatus and method according to the present invention possibly provide a human body detect function for personal authentication with high reliability.
