چکیده

A biometric system is essentially a pattern recognition system that operates by acquiring biometric data from an individual, extracting a feature set from the acquired data, and comparing this feature set against the template set in the database. Multimodal biometric systems are becoming more and more popular, they have more accuracy as compared to unimodal biometric systems. On the other hand these systems are more complex. We discuss here different types of multimodal biometric systems, different decision fusion techniques used in these systems. We discuss their feasibility and advantage over unimodal biometric systems & some of the future directions of biometrics system.

Fuzzy particle swarm optimization with nearest-better neighborhood for multimodal optimization

In the last decades, many efforts have been made to solve multimodal optimization problems using Particle Swarm Optimization (PSO). To produce good results, these PSO algorithms need to specify some niching parameters to define the local neighborhood. In this paper, our motivation is to propose the novel neighborhood structures that remove undesirable niching parameters without sacrificing perf...

Survey of Different Biometrics Techniques Biometrics Systems Personal Authenticati on Medical Diagnosis Future Expectation Ethnology Exploration

Biometrics is the study of automatically recognizing humans by means of inherently unique physical or behavioural characteristics. The human physical characteristics like fingerprints, face, hand geometry, voice, Signature, palm and iris are known as biometrics. These features are used to provide an authentication for computer based security systems. The existing computer security systems used ...

Level of Fusion in Multimodal Biometrics: a Review

User verification systems that use a single biometric indicator often have to contend with noisy sensor data, restricted degree of freedom, non-universality of the biometric trait and unacceptable error rates. So the need of using multimodal biometric system occurred. A multimodal biometric system combines the different biometric traits and provides better recognition performance as compared to...

An integrated authentication framework based on multi-tier biometrics

Biometric techniques exploit the human physiological and behavioural traits for verification and identification purposes. Biometrics powered systems make effective use of the face, fingerprint, iris etc. as physiological and signature, gait, posture and voice recognition as behavioural metrics for identification. This paper explains the inadequacy of uni-modal strategies and the pressing need f...
