Abstract： |
The invention is a multi-register fingerprint identification method belonging to fingerprint identification technology. its character lies in: it carries detail comparison to M fingerprints of the same finger in the databank, works out its similarity, and a excellent parameter is worked out according to the similarity, selects the maximal one as basic fingerprint, and it is copied onto the template; the other fingerprint is compared with its detail points, amends the confidence value of detail point according to the times of success comparisons, and a integral template is acquired; then carries tactics integration and finally integration matching with traditional detail joint character, acquires the similarity between the registered fingerprint and applied fingerprint. Compared with pure detail joint method, it reduces the error refusing rate. |
