Method and apparatus for invoking fingerprint identification device, and terminal

An apparatus for invoking a fingerprint identification device, comprising:

• a processor;
• and
• a memory, coupled with the processor and configured to store program codes which when executed by the processor become operational with the processor to:
• receive a request of a current application to invoke a fingerprint identification device to conduct fingerprint authentication;
• detect at least one other application requesting to invoke the fingerprint identification device simultaneously with the current application;
• determine whether a priority of the current application is higher than a priority of the at least one other application;
• when the priority of the current application is higher than the priority of the at least one other application, determine whether the fingerprint identification device is occupied by a historical application;
• when the fingerprint identification device is occupied by the historical application, determine whether the current application has stayed in a foreground for a preset time period;
• based on a determination that the current application has stayed in the foreground for the preset time period, determine whether the current application satisfies a preset invoking condition;
• and
• control the fingerprint identification device to process the request of the current application according to a determination result of whether the current application satisfies the preset invoking condition.

A terminal, comprising:

• a fingerprint sensor;
• a processor coupled with the fingerprint sensor;
• and
• a memory coupled with the processor and configured to store program codes which when executed by the processor become operational with the processor to:
• receive a request of a current application to invoke the fingerprint sensor to conduct fingerprint authentication;
• detect at least one other application requesting to invoke a fingerprint identification device simultaneously with the current application;
• determine whether a priority of the current application is higher than a priority of the at least one other application;
• when the priority of the currently application is higher than the priority of the at least one other application, determine whether the fingerprint sensor is occupied by a historical application;
• when the fingerprint sensor is occupied by the historical application, determine whether the current application has stayed in a foreground for a preset time period;
• based on a determination that the current application has stayed in the foreground for the preset time period, determine whether the current application satisfies a preset invoking condition;
• and
• control the fingerprint sensor to process the request of the current application according to a determination result of whether the current application satisfies the preset invoking condition.
