Provided is a fingerprint unlocking method used in an electronic device. The electronic device comprises a power button and an ultrasonic fingerprint identification device, wherein the ultrasonic fingerprint identification device is arranged opposite to the power button. The method comprises the steps of judging whether the screen of the electronic device is locked or not; if the screen of the electronic device is locked, detecting whether the power button of the electronic device is touched or pressed or not; if the power button is touched or pressed, controlling the ultrasonic fingerprint identification device to collect fingerprint information on the power button and verify the fingerprint information; if the fingerprint information passes the verification, unlocking the screen of the electronic device. The fingerprint unlocking method can improve the speed of fingerprint unlocking and makes it convenient for a user to perform the fingerprint unlocking operation.
Description
technical field [0001] The invention relates to the technical field of electronic equipment security, in particular to a fingerprint unlocking method and system. Background technique [0002] At present, with the development of communication technology, electronic devices such as mobile phones and tablets are widely used. In order to ensure data security of electronic devices, most electronic devices have a locking function. There are many ways to unlock electronic devices, such as pattern password unlocking, digital password unlocking, gesture password unlocking, ultrasonic fingerprint unlocking, etc. Existing ultrasonic fingerprint unlocking usually senses user fingerprints on the screen. In this case, it is necessary to control the crosstalk between signals such as fingerprints, touch screens, and screens. And, sensing the user's fingerprint on the screen requires specifying the location of the ultrasonic fingerprint sensing to the user. If the location of fingerprint...
