ntroduction The term “biometrics” defines the analysis of unique physiological or behavioral characteristics to verify the claimed identity of an individual.

Multibiometric systems Jain and Ross (2004) have been devised to overcome some of the limitations of unimodal biometric systems. In general terms, the combination of multiple biometric traits is operated by grouping multiple sources of information. These systems utilize more than one physiological or behavioral characteristic, or a combination of both, for enrollment and identification. For example, the problem of nonuniversality can be overcome, because multiple traits together always provide a sufficient population coverage. Multibiometrics also offers an efficient countermeasure to spoofing, because it would be difficult for an impostor to spoof multiple biometric traits of a genuine user simultaneously (Jain and Ross 2004). In some cases the sensor data can be corrupted or noisy, the use of multiple biometric traits always allow to reduce the effects of errors and noise in the data. Ross and Jain (2003) presented a wide overview of multimodal biometrics describing different possible levels of fusion, within several scenarios, modes of operation, integration strategies, and design issues.

Abstract

ntroduction The term “biometrics” defines the analysis of unique physiological or behavioral characteristics to verify the claimed identity of an individual. Biometric identification has eventually assumed a much broader relevance as a new technological solution toward more intuitive computer interfaces (Hong et al. 1999; Jain et al. 1999). Multibiometric systems Jain and Ross (2004) have been devised to overcome some of the limitations of unimodal biometric systems. In general terms, the combination of multiple biometric traits is operated by grouping multiple sources of information. These systems utilize more than one physiological or behavioral characteristic, or a combination of both, for enrollment and identification. For example, the problem of nonuniversality can be overcome, because multiple traits together always provide a sufficient population coverage. Multibiometrics also offers an efficient countermeasure to spoofing, because it would be difficult for an impostor to spoof multiple biometric traits of a genuine user simultaneously (Jain and Ross 2004). In some cases the sensor data can be corrupted or noisy, the use of multiple biometric traits always allow to reduce the effects of errors and noise in the data. Ross and Jain (2003) presented a wide overview of multimodal biometrics describing different possible levels of fusion, within several scenarios, modes of operation, integration strategies, and design issues.
