Abstract: A photoplethysmogram (PPG) authentication method and device, where it is detected whether a terminal currently meets a PPG signal pre-collection trigger condition, and collection of a current PPG signal of a user is triggered only when the PPG signal pre-collection trigger condition is met such that the PPG signal of the user is pre-obtained before an application requests PPG authentication. In this way, when it is detected that the application initiates a PPG authentication request, PPG authentication may be directly performed based on a most recently collected PPG signal, thereby ensuring timeliness of PPG authentication, avoiding resource consumption caused by periodic PPG signal collection, and reducing power consumption.

Abstract: This application discloses a method for controlling an electronic device to perform photoplethysmography detection. The method includes obtaining historical detection data of a photoplethysmography sensor, calculating a confidence of the historical detection data, determining, based on the calculated confidence of the historical detection data, whether a light source to be turned on by the photoplethysmography sensor in a next detection time segment includes a light source different from a light source turned on when the historical detection data is obtained, and determining that a photoelectric sensing element to be turned on in the next detection time segment is a photoelectric sensing element corresponding to the determined light source to be turned on.

Abstract: In a method, a terminal device obtains at least one template source file of a first contact in different ways, and when the terminal devices obtains a face picture in a currently displayed picture through facial recognition, and determines that a first face template included in a first face information template successfully matches the face picture, the terminal device sends, based on contact information, a multimedia file to a first contact to which the first face template belongs. The multimedia file is the picture, a picture set or a video file including the picture, or a picture or a video file generated based on the picture.

Abstract: Various embodiments relate to the field of communications technologies, and provide a light adjustment method and a terminal to resolve a problem that an existing light therapy device cannot flexibly adjust light based on a light requirement of a user and cannot more intelligently adjust a circadian rhythm of the user. In those embodiments, an awake time period and a sleep time period of a user is determined by the terminal, and parameter thresholds in the awake time period and the sleep time period is determined by the terminal. In those embodiments, a light parameter in a current time period is obtain by the terminal, and based on the light parameter in the current time period, a light parameter of light emitted by a light source device is then adjusted by the terminal.
