Abstract
Electronic devices having fingerprint authentication, and methods for controlling a fingerprint authentication on the electronic devices are provided. In one aspect, a method includes acquiring, using a first sensor on the electronic device, a first signal produced by an object positioned in proximity to the electronic device, and acquiring a second signal using a fingerprint sensor on the electronic device. The method also includes controlling a fingerprint authentication on the electronic device based on at least one of the first signal and the second signal.
Claims15
A method for controlling a fingerprint authentication on an electronic device, the method comprising:
- acquiring, using a first sensor on the electronic device, a first signal produced by an object positioned in proximity to the electronic device;
- acquiring a second signal using a fingerprint sensor on the electronic device;
- determining a strength of the first signal based on a sensed area of the first sensor that is activated by the object and a determined distance between the object and the electronic device;
- determining a strength of the second signal;
- controlling a fingerprint authentication on the electronic device based on the strength of the first signal and the strength of the second signal;
- controlling execution of a fingerprint unlocking function on the electronic device by comparing at least one of the strength of the first signal to a first preset threshold and the strength of the second signal to a second preset threshold;
- and
- executing the fingerprint unlocking function when at least one of the strength of the first signal is smaller than or equal to the first preset threshold and the strength of the second signal is larger than or equal to the second preset threshold.
An electronic device having a fingerprint authentication, the electronic device comprising:
- a first sensor configured to acquire signals from objects near the electronic device;
- a fingerprint sensor configured to acquire a user fingerprint;
- a processor programmed to execute instructions stored in a memory to:
- receive a first signal produced by an object near the electronic device and acquired using the first sensor;
- receive a second signal acquired using the fingerprint sensor on the electronic device;
- determine a strength of the first signal based on a sensed area of the first sensor that is activated by the object and a determined distance between the object and the electronic device;
- determine a strength of the second signal;
- control a fingerprint authentication on the electronic device based on the strength of the first signal and the strength of the second signal;
- control execution of a fingerprint unlocking function by comparing at least one of the strength of the first signal to a first preset threshold and the strength of the second signal to a second preset threshold;
- and
- execute the fingerprint unlocking function when at least one of the strength of the first signal is smaller than or equal to the first preset threshold and the strength of the second signal is larger than or equal to the second preset threshold.
A non-transitory computer-readable storage medium having stored therein instructions that, when executed by a processor, causes the processor to perform a method for controlling a fingerprint authentication, the method comprising:
- acquiring, using a first sensor on an electronic device, a first signal produced by an object positioned in proximity to the electronic device;
- acquiring a second signal using a fingerprint sensor on the electronic device;
- determining a strength of the first signal based on a sensed area of the first sensor that is activated by the object and a determined distance between the object and the electronic device;
- determining a strength of the second signal;
- controlling a fingerprint authentication on the electronic device based on the strength of the first signal and the strength of the second signal;
- controlling execution of a fingerprint unlocking function on the electronic device by comparing at least one of the strength of the first signal to a first preset threshold and the strength of the second signal to a second preset threshold;
- and
- executing the fingerprint unlocking function when at least one of the strength of the first signal is smaller than or equal to the first preset threshold and the strength of the second signal is larger than or equal to the second preset threshold.
