A biometric verification system and methods for using thereof are disclosed. The biometric verification system may comprise a verification engine for verifying an identity of a subject and a training engine. The verification engine may comprise a plurality of discriminators, a discriminator fusion component, and a subset fusion component. The discriminators analyze biometric inputs to generate a plurality of distortion scores. The discriminator fusion component analyzes the distortion scores utilizing a plurality of reference user models and a discriminator reliability ranking to obtain a combined confidence score for biometric sets of the subject in question. The subset fusion component analyzes the distortion scores for a plurality of biometric subsets utilizing subset selection-criteria to generate a combined confidence score for the biometric subsets of a subject in question. The verification engine may also include logic capable of determining whether to accept the subject in question as a genuine subject based on the combined confidence scores.
