1. A user verification method performed by a controller of a user verification apparatus, the method comprising:
obtaining a plurality of biometric verifiers, at least one biometric verifier of the plurality of biometric verifiers being configured to perform a verification process that terminates at any one of a plurality of successive verification stages, wherein each verification stage of the plurality of successive verification stages corresponds to at least one of a particular verification performance, a particular verification accuracy, and a particular verification speed, wherein each biometric verifier of the plurality of biometric verifiers is implemented as a neural network, and the plurality of successive verification stages of the biometric verifier correspond to a plurality of successive layers of the neural network;
setting, based on a particular criterion, a termination stage of each biometric verifier of the plurality of biometric verifiers by selecting the termination stage from the plurality of successive layers of the neural network, such that each biometric verifier of the plurality of biometric verifiers is associated with a separate termination stage of a particular combination of termination stages, respectively, wherein the termination stage of each biometric verifier is one of the plurality of successive verification stages, wherein the particular criterion includes a sensing environment associated with the user verification apparatus;
executing the plurality of biometric verifiers, based on the particular combination of termination stages associated with the plurality of biometric verifiers, to generate a plurality of outputs;
fusing the plurality of outputs based on the particular combination of termination stages associated with the plurality of biometric verifiers to generate a result; and
verifying a user based on the result.
