Method and apparatus for verifying user using multiple biometric verifiers

A user verification apparatus, comprising:

• a memory storing a program of instructions;
• and
• a processor configured to execute the program of instructions to
• obtain a plurality of biometric verifiers, at least one of the biometric verifiers being configured to perform a verification process that terminate at any one of a plurality of successive verification stages,
• set a termination stage of each biometric verifier of the plurality of biometric verifiers, 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,
• execute 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,
• fuse the plurality of outputs based on the particular combination of termination stages associated with the plurality of biometric verifiers to generate a result, and
• verify a user based on the result.

A smart phone, comprising:

• a memory storing a program of instructions;
• and
• a processor configured to execute the program of instructions to
• obtain a plurality of biometric verifiers, at least one of the biometric verifiers being configured to perform a verification process that terminate 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,
• set a termination stage of each biometric verifier of the plurality of biometric verifiers, 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,
• execute 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,
• fuse the plurality of outputs based on the particular combination of termination stages associated with the plurality of biometric verifiers to generate a result, and
• verify a user based on the result.
