Claim 4:
5. The method according to claim 4, wherein the performing living body detection on the biometric feature image in the local safe area, to obtain a detection result comprises:
extracting, by using a convolutional layer of an identification model, a feature map representing biometric features from the biometric feature image in the local safe area;
classifying the biometric feature image according to the feature map by using a fully connected layer of the identification model, to obtain a confidence level at which the biometric feature image is a living body biometric image, the confidence level representing a probability that a living body is detected; and
determining that a living body is detected in response to the confidence level being greater than or equal to a confidence threshold.
