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.
