Abstract: Embodiments of this application provide a stylus-based data processing method and apparatus, which are applied to a communication system. The communication system includes a stylus and an electronic device. The electronic device displays a first interface. After a user performs a first operation on a first target area in the first interface by using the stylus, the electronic device may determine first target content in the first target area. The stylus may obtain the first target content from the electronic device, and obtain a first target result corresponding to the first target content. The electronic device may obtain the first target result from the stylus and display the first target result on the first interface.

Abstract: Embodiments of this application provide a method and a system for generating a note. The method includes detecting, by an electronic device, drawing a plurality of discontinuous underlines by a stylus on a touchscreen of the electronic device; combining, by the electronic device, a content selected by the discontinuous underlines to obtain a to-be-stored content; displaying, by the electronic device, a previous box comprising the to-be-stored content; controlling, by the electronic device, a target device to store the to-be-stored content, where the target device is at least one of the electronic device and the stylus; and outputting, by the target device, the to-be-stored content. In the embodiments of this application, a storage function of the electronic device and/or the stylus is used to output the to-be-stored content required by a user as a separate note, which facilitates convenience for the user to read key notes and improves user experience.

Abstract: A fingerprint recognition method and an electronic device are provided. The method includes collecting a touch image in a fingerprint collection region of the fingerprint recognition sensor; configuring a correspondence list; determining whether the touch image is consistent with a pre-stored fingerprint sample; and if the touch image is consistent with the pre-stored fingerprint sample, executing a first preset action corresponding to the fingerprint sample; or if the touch image is inconsistent with the pre-stored fingerprint sample, determining whether the touch image meets a preset condition; and if the touch image meets the preset condition, executing a second preset action, calculating a quantity of times of continuously executing the second action, and if the quantity of times of continuously executing the second preset action is greater than or equal to a third preset value, locking the electronic device within a preset time.
