Embodiments may include a method and apparatus for detecting model reliability. A method may include: acquiring an infrared reflection image and a visible light reflection image of a photographed non-living body; importing the infrared reflection image and the visible light reflection image into a to-be-detected living body detection model, to obtain a detecting result corresponding to the infrared reflection image and a detecting result corresponding to the visible light reflection image; and matching a set concentration level of the infrared reflective coating on the photographed non-living body with the detecting results, and setting a reliability level of the to-be-detected living body detection model based on the matching results.
