Abstract: To study a new fingerprint recognition algorithm and application in electric control lock.In view of the traditional fingerprint recognition algorithm of fingerprint minutiae matching accuracy is low, difficult to detail information for accurate extraction, in order to overcome this problem, based on point pattern matching algorithm of fingerprint recognition is improved, the improved algorithm in pattern matching algorithm based on the joined the matching weight coefficient, can effectively improve the fingerprint recognition accuracy, and gives the hardware structure of fingerprint identification, this improved algorithm is successfully applied in the electric control lock embedded application, the result shows that, the proposed algorithm can effectively encrypt lock, has a certain practical value.
