Abstract
The present invention discloses a fingerprint template and a fingerprint identification method based on fuzzy feature point information. The fingerprint template contains several pieces of incomplete feature point information, including registration information and comparison information, wherein only coordinate information and attribute information of feature points and a value of a polynomial are recorded. In the polynomial P(X)=C+CX+CXi. . . CX, n is an order of the polynomial, and Xi is a numerical value obtained by quantifying one or multiple pieces of feature point information except the registration information in the feature point information and is a coefficient having a certain preset rule. Corresponding feature point information of a scene fingerprint is substituted into the polynomial to figure out C-C, and whether the C-Cmeet the preset rule is judged to judge whether the scene fingerprint is matched with a template fingerprint.
