Patent ID: 8335926

Claim:
A system for identifying a specific individual using a biometric characteristic of the specific individual, comprising: a computer system comprising a first database containing a dynamic binary code conversion algorithm, and a second database including a sequence of binary codes generated sequentially by means of the dynamic binary code conversion algorithm; a housing containing a biometric sensor located so as to be receptive to a defined biometric characteristic and operable to generate a sensor code in response to the detection of the defined biometric characteristic; a controller device in the housing and operably connected to the biometric sensor, the controller device including a memory configured for storing (i) a first code representing the defined biometric characteristic of the specific individual and (ii) the dynamic binary code conversion algorithm; a first communication device in the housing and operably controlled by the controller device so as to establish communication between the controller device and the computer system; a second communication device operably associated with the computer system so as to establish communication between the computer system and the controller device; and a visual display device controlled by the controller device; wherein the controller device, upon receiving the sensor code from the biometric sensor, performs a comparison between the sensor code and the first code stored in the memory, and, if the comparison verifies the identity between the sensor code and the first code, generates a first pin code by means of the dynamic binary code conversion algorithm and outputs the first pin code by means of the first communication device to the computer system; wherein the dynamic binary code conversion algorithm generates the first pin code based on at least a random number generated via the controller and predetermined personal identification information; wherein the computer system generates, upon receiving the first pin code by means of the second communication device, a second binary code by means of the dynamic binary code conversion algorithm and verifies the identity of the specific individual if the second binary code matches the first pin code; wherein, if the second binary code does not match the first pin code, the computer system compares the first pin code with the sequence of binary codes contained in the second database so as to verify the identity of the specific individual if the first pin code matches one of the binary codes in the sequence of binary codes; and wherein the visual display device is controlled by the controller device so as to display the first pin code as an alphanumeric code after verification of an identity between the sensor code and the first code.
