However, in the above process, as long as the user's skin is detected, the fingerprint recognition function will be activated and subsequent steps will be performed, even if the skin is not touched by a fingerprint, the power consumption of the terminal system will be relatively large

The invention discloses a fingerprint identification method and device, and belongs to the technical field of terminals. The method comprises the following steps: when a contact operation on a fingerprint identification area of a terminal by any target object is detected, obtaining feature information of a contact surface; judging whether the contact surface of the target object contains fingerprint according to the feature information; if the contact surface of the target object contains fingerprint, starting a fingerprint identification function to perform fingerprint identification; and if the contact surface of the target object contains no fingerprint, ignoring the contact operation, and keeping a sleep state of the fingerprint identification function. When the contact operation on the fingerprint identification area is detected, whether the next target object is a user finger is judged at first, namely whether the contact surface of the target object contains fingerprint, if the next target object is the user finger, it indicates that the contact operation is effective, the fingerprint identification function is started to perform the fingerprint identification, and if the next target object is not the user finger, the fingerprint identification function is not started, and thus unnecessary power consumption caused by some misoperations is avoided.
Description
technical field [0001] The present disclosure relates to the technical field of terminals, and in particular to a fingerprint identification method and device. Background technique [0002] With the development of terminal technology, many terminals have a fingerprint identification function. The fingerprint identification function can collect the user's fingerprint and match it with the pre-stored fingerprint template, so as to realize certain functions of the terminal according to the matching result, such as terminal screen unlocking, application decryption, and mobile payment. [0003] For any fingerprint identification process, when the terminal detects the user's skin through the fingerprint identification module, it will start the fingerprint identification function and perform fingerprint collection and fingerprint matching after activation, and then perform subsequent functions based on the fingerprint matching results. However, in the above process, as long as the...
