Use sensitive tokenless identification system

摘要

The system includes a master computer having a master computer comparator. The master computer comparator further having a master user biometric database which contains or stores the biometric samples of all users registered with the identification computer system. The master computer further includes a user personal identification code group database which contains the personal identification codes of said users. The identification computer system further includes at least two local computers which are physically remote from each other. Each local computer further includes a biometric scanner; a local comparator; a data entry device; and a local user biometric database containing a subset of the biometric samples contained in the master biometric database. First interconnectors that interconnects each local computer to the master computer. When the user enters their bid biometric sample and bid personal identification code into a first local computer, the first local computer comparator compares the bid biometric sample and bid personal identification code against biometric samples and personal identification codes contained in the first local computer database to produce either a failed or successful first identification result. If the first local computer returns a failed identification result, the bid biometric sample and bid personal identification code are transmitted to the master computer for comparison of the entered bid biometric sample and bid personal identification code to personal identification codes and biometric samples stored in the master computer for producing either a failed or successful second identification result. The result of the first or second identification result is externalized from the identification computer system or displayed to the user by a display unit.
