1. one kind is used for by reference fingerprint comprising step through the method to the comparison fingerprint that relatively comes biology ground identifier between the reference details of the comparison details of fingerprint relatively and reference fingerprint:

  • It is right to the baseline of forming by first and second details to confirm, these two details are to constituting by the first and second comparison details that correspond to each other with reference to details respectively;

    Compare details and right from other that corresponds to each other respectively with reference to definite a plurality of other details the details;

    By said baseline to all other details of confirming to judging this people'"'"'s comparison fingerprint;

    It is characterized in that,By fixed details to the definition from said baseline to the beginning details to sequence, it is right that this sequence extends to determined each other details;

    AndOther details to be utilize at least 3 that confirmed, by its in benchmark details that this details is confirmed the position in the sequence under following condition, confirming;

    the geometric relationship between the comparison details of the comparison fingerprint that the comparison details of the comparison fingerprint that promptly this other details is right and this benchmark details are right drops in the predetermined range of tolerable variance of the geometric relationship between the reference details of the right reference fingerprint of reference details and the benchmark details of the right reference fingerprint of this other details.
