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

Abstract

The disclosure provides a fingerprint identification method and device, which belong to the technical field of terminals. The method includes: when any target object is detected to touch the fingerprint identification area on the terminal, acquiring characteristic information of the contact surface; judging whether the contact surface of the target object contains fingerprints according to the characteristic information; if the contact surface of the target object contains fingerprints, , then start the fingerprint recognition function for fingerprint recognition; if the contact surface of the target object does not contain fingerprints, then ignore the contact operation, so that the fingerprint recognition function remains in a sleep state. When the touch operation to the fingerprint recognition area is detected, first judge whether the target is the user's finger, that is, whether the contact surface of the target contains fingerprints, if it is the user's finger, it means that the touch operation is valid, and then start The fingerprint identification function performs fingerprint identification, and if it is not the user's finger, the fingerprint identification function is not activated, thereby avoiding unnecessary power consumption caused by some misoperations.

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 recognition 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 us...
