Information access method using biometrics authentication and information processing system using biometrics authentication

An information processing system using biometrics authentication for individual authentication and accessing of information relating to the individual of said individual authentication is permitted, comprising:

• a detection device, which detects the relevant portion of said biometrics characteristics;
• an input unit, which inputs a group number of said user;
• a biometrics database file, which stores said group number, a plurality of individual identification numbers belonging to the group of the group number, and biometrics characteristic data linked to said individual identification numbers;
• an individual database file, which stores individual information for said user linked to said individual identification numbers;
• and
• a control unit which reads the corresponding individual identification numbers and said biometrics characteristic data from said biometrics database file according to input said group number, and performs processing to verify said biometrics characteristic data obtained from said biometrics characteristic portion detected by said detection device against said read-out biometrics characteristic data;
• wherein said control unit executes access of said individual database file using said individual identification number linked to said biometrics characteristic data for which the result of said verification is satisfactory.
