This application provides an operation determination method based on expression groups, apparatus and electronic device therefor, and relates to the technical field of image processing. The method is executed by an electronic device. The method comprises: obtaining a current human face image of a target object; performing a live body human face identification on the target object based on the current human face image, determining whether an identity of the target object is legal according to an identification result; the live body human face identification comprises a live body identification and a human face identification; if legal, obtaining a current expression group of the current human face image; determining an instruction to be executed corresponding to the current expression group; performing an operation corresponding to the instruction to be executed.
