While each biometric modality offers distinct advantages and disadvantages, the layered use of several biometrics in concert is fast becoming the standard for applications which require strong protection of sensitive information. Identity management through multiple biometrics (or the combination of biometrics and traditional identification methods) offers even higher accuracy rates than the use of a single biometric. Multimodal biometrics offer users and system administrators the convenience of confirming their identities in many different ways, along with the security that comes with increased accuracy of identification.
Advantages of multimodal biometrics:
- Increases accuracy of identification to near 100%
- Added security benefits of back-up forms of identification should one factor fail to match
- Creates a more sophisticated challenge to mala fide actors
