Information Fusion in Biometrics: A Case Study in Online Signature

Biometrics is constantly evolving technology which has been widely used in many official and commercial identification applications. A biometric system is essentially a pattern recognition system which makes a personal identification decision by determining the authority of specific physiological or behavioral traits. Despite considerable advances in recent years, there are still challenges in authentication based on a single biometric trait, such as noisy data, restricted degree of freedom, intra-class variability, non-universality, spoof attack and undesirable error rates. Some of the restrictions can be lifted by designing a multimodal biometric system. Multimodal biometric systems are those which utilize, or are capable of utilizing, more than one physiological or behavioral characteristic for enrollment either in verification or identification mode.
