Abstract
A device includes a power button and a fingerprint sensor, where the power button is integrated with the fingerprint sensor. A method is applied to a process in which a user presses the power button to start up the device. The method includes obtaining fingerprint information acquired by the fingerprint sensor, and saving the fingerprint information. The method further includes obtaining a fingerprint authentication request. The method further includes providing the fingerprint information to perform fingerprint authentication to log in to an operating system of the device.
Claims21
A method for starting up a device, comprising:
- obtaining fingerprint information from a fingerprint sensor integrated with a power button configured to start up the device when pressed;
- saving the fingerprint information;
- obtaining a fingerprint authentication request;
- and
- providing, in response to the fingerprint authentication request, the fingerprint information to perform fingerprint authentication to log in to an operating system of the device.
A method for starting up a device, the method comprising:
- receiving, by a first microcontroller unit (MCU), a wakeup indication from a fingerprint sensor integrated with a power button configured to start up the device when pressed;
- obtaining, by the first MCU and responsive to receiving the wakeup indication, fingerprint information acquired by the fingerprint sensor;
- saving the fingerprint information;
- receiving, by the first MCU, a fingerprint authentication request from a fingerprint drive;
- and
- providing, in response to the fingerprint authentication request, the fingerprint information to the fingerprint drive to cause the fingerprint drive to perform fingerprint authentication to log in to an operating system of the device.
-29. (canceled)
A device, comprising:
- a power button;
- a fingerprint sensor integrated with the power button;
- a processor coupled to the power button and the fingerprint sensor;
- and
- a memory coupled to the processor and storing instructions that, when executed by the processor, cause the processor to be configured to:
- obtain fingerprint information from the fingerprint sensor;
- save the fingerprint information;
- obtain a fingerprint authentication request;
- and
- provide, in response to the fingerprint authentication request, the fingerprint information to perform fingerprint authentication to log in to an operating system of the device.
