Abstract
A fingerprint recognition method and an electronic device are provided. The method includes collecting a touch image in a fingerprint collection region of the fingerprint recognition sensor; configuring a correspondence list; determining whether the touch image is consistent with a pre-stored fingerprint sample; and if the touch image is consistent with the pre-stored fingerprint sample, executing a first preset action corresponding to the fingerprint sample; or if the touch image is inconsistent with the pre-stored fingerprint sample, determining whether the touch image meets a preset condition; and if the touch image meets the preset condition, executing a second preset action, calculating a quantity of times of continuously executing the second action, and if the quantity of times of continuously executing the second preset action is greater than or equal to a third preset value, locking the electronic device within a preset time.
