Abstract

The disclosure reveals a voiceprint identification method and device, and belongs to the voiceprint identification technical field; the voiceprint identification method comprises the following steps: obtaining a sound signal collected by a microphone, and obtaining a voiceprint characteristic of the sound signal; matching the voiceprint characteristic with a stored sample voiceprint characteristic, wherein the sample voiceprint characteristic is the voiceprint characteristic of a terminal valid user; if the obtained voiceprint characteristic is not matched with the sample voiceprint characteristic, sending prompt information to a notified party set by the valid user. In the prior art, a terminal unlocking code can be easily sensed and decrypted by an invalid user, thus causing the terminal to be lost or the terminal cannot be retrieved; the voiceprint identification method and device solve said problems, can identify invalid users, and can timely inform the terminal valid user.

Description

technical field [0001] The present disclosure relates to the technical field of voiceprint recognition, in particular to a voiceprint recognition method and device. Background technique [0002] In daily life, once a mobile phone is stolen, in order to prevent illegal users from using the stolen mobile phone and causing information leakage in the mobile phone, legitimate users usually set the unlocking password of the mobile phone. Only when the obtained unlocking password is correct, the mobile phone will be successfully unlocked. [0003] In related technologies, unlocking passwords are usually gesture passwords, digital passwords, fingerprint passwords, etc. The design of such passwords is easy for illegal users to perceive the set password barriers and crack them. Therefore, once the mobile phone is lost or stolen, it will be difficult for users to pass the settings Unlock the password to retrieve the terminal. Contents of the invention [0004] In order to solve the...
