Provided are a method for controlling fingerprint processing resources, a terminal, and a computer readable storage medium. The method includes the following. A terminal adds, in a predetermined order, N access requests for the fingerprint processing resources initiated concurrently by N applications of the terminal to a predetermined access queue upon detecting the N access requests, where, in the predetermined access queue, an access request first added is first processed, and N is an integer greater than one. The terminal allocates the fingerprint processing resources to an application corresponding to an access request currently processed in the predetermined access queue, and updates the access request currently processed in the predetermined access queue according to a duration in which the application occupies the fingerprint processing resources.

Embodiments of the present disclosure provide unlocking control methods and related produces. The method includes the following. A face image is collected. A first operation and a second operation are performed in parallel. The first operation is configured to detect whether the face image is a real face image. The second operation is configured to extract feature data of the face image. The feature data of the face image is matched with feature data of a preset face template when the feature data of the face image is extracted and the face image is detected to be the real face image. An unlocking operation is performed when the feature data of the face image is matched with the feature data of the preset face template.

Unlocking control methods and related products

A method and an apparatus for invoking a fingerprint identification device are provided. The method includes the following. When a request of a current application to invoke a fingerprint identification device is detected, whether the fingerprint identification device is occupied by a historical application is determined. When the fingerprint identification device is occupied by the historical application, whether the current application meets a preset invoking condition is determined, and then the fingerprint identification device is controlled to process the request of the current application according to the determination result.

A fingerprint enrolling method, a fingerprint enrolling apparatus, and a terminal device are provided. The method includes the following operations. Whether an image-quality fluctuation amplitude of fingerprint images of a user exceeds a preset image-quality fluctuation threshold or image-quality fluctuation threshold range is determined according to image quality of a current fingerprint image of the user currently acquired and image quality of a historical fingerprint image of the user previously acquired. The current fingerprint image is enrolled into a fingerprint database based on a determination that the image-quality fluctuation amplitude does not exceed the image-quality fluctuation threshold or the image-quality fluctuation threshold range.

A method and an apparatus for determining existence of a foreign material on a surface of a fingerprint sensor of a terminal are provided. The method includes the following. A current capacitance value of the fingerprint sensor of the terminal is obtained. A first difference between the current capacitance value and a preset capacitance reference value is calculated. Determine that the foreign material is present on the surface of the fingerprint sensor when the first difference is within a preset foreign-material threshold range. The preset capacitance reference value is a capacitance value tested with no foreign material on the surface of the fingerprint sensor before leaving the factory and is stored in a system in advance. The preset foreign-material threshold range is set in advance according to experimental data of capacitance-change tests performed on the fingerprint sensor when different conductive foreign materials are on the surface of the fingerprint sensor.
