  • Computer system and biometric authentication apparatus for use in a computer system
    Patent number: 8335926
    Abstract: A computer system for identifying an individual using a biometric characteristic of the individual includes a biometric sensor for generating a first code, and a controller including a memory for storing the first code and a dynamic binary code conversion algorithm. When the controller receives a sensor code from the biometric sensor, it compares the sensor code with the first code stored in the memory, and if the identity between the sensor code and the first code is verified, the controller generates a first binary code by means of the dynamic binary code conversion algorithm and outputs the first binary code from which the computer system generates a second binary code by means of the dynamic binary code conversion algorithm. The computer system then verifies the identity of the individual if the second binary code matches the first binary code.
