Referring to FIG. 1, Fig. 1 is a kind of flow chart of user ID authentication method in the embodiment of the present invention, this method can be answered
With in fingerprint logger, fingerprint logger and target terminal are established and communicated to connect, when user demand logs in target terminal, just
It can will be by fingerprint logger typing finger print information to carry out authentication.
The auth method the following steps are included:
S101, the fingerprint image that target user is acquired using fingerprint sensor, and the fingerprint characteristic for the image that takes the fingerprint.
Wherein, fingerprint sensor (fingerprint Sensor) is the Primary Component for realizing fingerprint automatic collection.Implement in the present invention
In example, fingerprint sensor can collect fingerprint image, unlimited to its model and working principle etc., therefore can be selected
Optical fingerprint sensor, semicoductor capacitor sensor, semiconductor heat dependent sensor, semiconductor pressure sensor, supersonic sensing
The common fingerprint sensor such as device and radio frequency sensor, the work of this is no longer going to repeat them fingerprint sensor acquisition fingerprint image
Make principle.
After fingerprint logger collects the fingerprint image of target user using its included fingerprint sensor, it can extract
