This application involves the field of communication technology, especially the authentication technology in the terminal, in a PPG authentication method, by detecting whether the terminal is currently satisfied with the triggering condition of the pre acquisition of the PPG signal, and only when the triggering condition of the pre acquisition of the PPG signal is met, the current PPG signal of the user is collected. The user's PPG signal is obtained prior to the application request PPG authentication, so that when the application initiates the PPG authentication request, the PPG authentication can be carried out directly according to the PPG signal collected recently, which helps to ensure the timeliness of the PPG authentication, and the resource consumption caused by the periodic collection of PPG signals can also be avoided. It is beneficial to reduce power consumption.
