Abstract:
1. A fingerprint identification method of making fingerprint identification based on fingerprint collation with individual fingerprint collation trial values of FARx and FRRx, the method comprising: a registering step of registering fingerprint patterns of a plurality of (i.e., m) fingers of a person to be identified by the method; an m-finger collation step of executing, at the time of identification, an individual fingerprint collation trial for each of the plurality of m fingers; an n-time collation step of executing the individual fingerprint collation trial a plurality of (i.e., n) times for each of the plurality of m fingers; and an identifying step of judging and outputting the identification result by combining the results of the m-finger collation and n-time collation steps, wherein, in the n-time collation step, when the individual collation trial is judged to be successful even once in the n individual collation trials, the collation is judged to be successful with respect to that finger, and in the m-finger collation step, when the collation is judged to be successful with respect to all the m fingers, a judgment of identification success (acceptance) is given; and a defining step of defining values of FAR and FRR for the identification result by setting values of FARx, FRRx, m and n prior to executing the method, wherein the FAR for the identification result is defined as FAR(m, n)=n
