Patents Assigned to REAL IDENTITY CO., LTD.
  • 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.
