Authentication device and electronic device

Abstract

The invention relates to an authentication device and an electronic device, and the device comprises a first module which is used for determining the type of a received triggering signal, and outputting a first control signal under the condition that the triggering signal is a first authentication signal; a second module electrically connected to the first module and used for acquiring first fingerprint information according to the first control signal, performing fingerprint identification on the first fingerprint information by utilizing a first fingerprint identification algorithm and outputting an identification result; and a third module electrically connected to the first module and the second module, and used for controlling the electronic device to change the state under the condition that the identification result of the second module is that the identification is successful. According to the invention, when a user triggers the first authentication signal, in response to the first authentication signal, the second module is used to rapidly carry out fingerprint information acquisition and fingerprint identification, and in the case of successful identification, rapid authentication is carried out, so that the authentication speed can be greatly improved, the authentication time is reduced, and the user experience is improved.

Description

technical field

[0001] The present disclosure relates to the technical field of fingerprint identification, and in particular to an authentication device and electronic equipment. Background technique

[0002] With the development of technology, the services provided by mobile devices to users are not limited to communication and entertainment, but also include all aspects of life and work. important information of users; fingerprints, as a biometric feature that can identify people, have been widely used in the field of mobile device security. At present, many mobile phones have fingerprint collection functions, which can collect user fingerprints and provide verification services in scenarios such as mobile phone authentication and mobile payment. However, mobile devices using fingerprint technology consume a lot of power, and many mobile devices are sensitive to power consumption. , so the system will enter the dormant state after a period of inactivity, and the mobile d...
