Problems solved by technology
In related technologies, the fingerprint data of the user is collected by a fingerprint sensor, and when the similarity between the collected fingerprint data and the stored reference fingerprint reaches a preset threshold, fingerprint unlocking is performed; when the similarity does not reach the preset threshold, If the fingerprint unlocking fails, the electronic device will record an unlocking failure. When multiple unlocking failures are achieved through the above process, the electronic device will be disabled, affecting the normal use of the electronic device by the user

The present disclosure relates to a method and device for realizing fingerprint unlocking, and electronic equipment. The method includes: determining a first intensity value of a suspended signal of a suspended object; determining a second intensity value of a fingerprint signal collected by a fingerprint sensor; when the first intensity value is greater than the first preset threshold and / or the When the second intensity value is less than the second preset threshold, the electronic device is controlled to turn off the fingerprint unlocking function. The technical solution of the present disclosure can prevent the electronic device from triggering fingerprint identification and fingerprint matching when it is covered by an obstruction, thereby preventing the electronic device from still enabling the fingerprint unlocking function when the fingerprint sensor is touched by mistake, thereby reducing the number of electronic devices to enable the fingerprint unlocking function. times to ensure the normal use of electronic equipment.
Description
technical field [0001] The present disclosure relates to the technical field of terminals, and in particular to a method and device for realizing fingerprint unlocking, and electronic equipment. Background technique [0002] With the advancement of technology, biometric features are gradually being applied to consumer electronic devices, and fingerprint authentication is used for identification, which saves users from the trouble of entering authentication passwords through keyboards. In related technologies, the fingerprint data of the user is collected by a fingerprint sensor, and when the similarity between the collected fingerprint data and the stored reference fingerprint reaches a preset threshold, fingerprint unlocking is performed; when the similarity does not reach the preset threshold, If the fingerprint unlocking fails, the electronic device will record one unlocking failure. When multiple unlocking failures are achieved through the above process, the electronic d...
