1. A living body detection method that is performed by an electronic device, the method comprising:
traversing a plurality of images of a to-be-detected object and using a currently traversed image as a current image;
performing face feature extraction on the current image to obtain an eigenvector corresponding to the current image, the eigenvector being used for describing a structure of a face feature of the to-be-detected object in the current image;
capturing an action behavior of the to-be-detected object in response to a change of the eigenvector corresponding to the current image relative to an average value of a plurality of eigenvectors in a feature sequence being less than a change threshold, each of the plurality of eigenvectors corresponding to a historical image in the feature sequence, where the historical image is a traversed image in the plurality of images; and
determining the to-be-detected object as a living body in response to capturing the action behavior of the to-be-detected object.
