Title:
FINGERPRINT PROCESSING METHOD, DEVICE AND MOBILE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2018/129966
Kind Code:
A1
Abstract:
A fingerprint processing method, a device and a mobile terminal. The method comprises: when a touch operation by a user is detected, acquiring a user fingerprint image (S101); extracting fingerprint features in the fingerprint image (S102); matching the fingerprint features with fingerprint templates in a fingerprint database (S103); if a matching fingerprint template matched with the fingerprint features is found in the fingerprint database, performing a fingerprint unlocking operation, and denoting the matching fingerprint template as a first fingerprint template (S104); and acquiring difference features between the fingerprint features and the first fingerprint template (S105); adding the difference features into the first fingerprint template to correct the first fingerprint template to obtain a second fingerprint template (S106); and replacing the first fingerprint template in the fingerprint database with a second fingerprint template (S107). By using the method, the device and the mobile terminal, the correction of the fingerprint template can be achieved, thereby improving the matching degree between the input fingerprint of a user and the fingerprint templates, and improving the sensitivity of fingerprint unlocking.
