A Survey on Different Levels of Fusion in Multimodal Biometrics


Objectives: In this paper, we have compiled a survey which is based on the comparison of various fusion techniques which are most commonly used in a multimodal biometric system. Methods/Statistical Analysis: The Multimodal Biometric systems are providing identification and human security over last few decades. We have also discussed various techniques used in different level of fusion with the objective of improving performance and robustness at each level of fusion. Findings: The extensive study shows that almost perfect accuracy rates can be achieved by multimodal fusion based protection processes. A comparison has also been made depending upon fusion levels, acceptance rates and accuracy levels. It is concluded from the fact that a combination of two identities when fused together, can reach very high accuracy levels. Applications: The survey given in this paper will help researchers in understanding levels of fusion in multimodal biometrics.
