S2504, traversing the E, obtaining the maximum similarity from the E, and taking the maximum similarity as the target similarity F'.
As described above, when the number of the maximum similarity degrees in F is 1, it can be understood that only one of the associated ID similarity degrees corresponding to the third intermediate fingerprint is the highest, that is, the maximum similarity degree is taken as the target similarity degree; when the number of the maximum similarities in F is greater than 1, it can be understood that there are a plurality of the highest associated ID similarities corresponding to the third intermediate fingerprint, and at this time, another method for obtaining F is adopted to further obtain the maximum similarity F', and the maximum similarities obtained by the two methods are more accurate.
