Title: Multi-Modal Biometrics: Orthogonal, Independent, and Collaborative
Abstract: The topic of multi-modal biometrics has attracted great interest in recent years. This talk will categorize different approaches to multi-modal biometrics based on the biometric sources, the type(s) of sensing used, and the depth of collaborative interaction in the processing. By “biometric source” we mean the property of the person that is used for identification, such as fingerprint, voice, face appearance or iris texture. By “type of sensing” we mean different sensor modalities, such as 2D, 3D, or infra-red. By “collaboration” we mean the degree to which the processing of one biometric is influenced by the results of processing other biometrics. One common category of multi-modal biometrics might be called “orthogonal.” In this category, the biometric sources are different, such as face plus fingerprint used as a “multi-modal biometric” or a “multi-biometric.” In this category, there appears to be little or no opportunity for interaction between the processing of the individual biometrics. Another common category of multi-modal biometrics might be called “independent.” This type of processing is common with different modalities of sensing the face. For example, the 2D image of the face and the 3D shape of the face might be processed independently as biometrics, and then two results combined at a score or rank level. A less common category of multi-modal biometrics might be called “collaborative.” In this category, the processing of each individual biometric may be influenced by the other biometrics. For example, if specular highlights are found in the 2D face image, this might inform the processing of the 3D shape of the face, since specular highlights in the 2D often result in artifacts in the 3D shape. It is argued that the area of “collaborative” processing among multi-modal biometrics, although relatively less explored, holds the potential for important gains in accuracy.

Title: Fusing Noncontact Biometrics: Face, Gait and Ear
Abstract: This talk will describe progress in multimodal biometric fusion and in the newer vision-based biometrics, ear and gait. The current interest in multimodal biometric fusion arises not only from ability to improve enrolment, but also from the potential performance advantage achieved by fusing complementary technologies. Currently there are two portal systems in development aiming to provide fusion based access control, one using face and iris and the other using face, gait and ear. Gait is attractive as a biometric since it concerns motion, is available at a distance and can cue acquisition of other biometrics. Ears are attractive as a biometric since their structure changes little with age and their covariate structure is considerably less complex than other approaches. As such, this talk will encompass two of the newer vision-based biometrics and whilst describing progress, also assess suitability for deployment in a multimodal biometric system.

Title: Government initiatives concerning biometric authentication and their impact on the industry and international standards
Abstract: The international community has now been working on delivering the first ePassports for some three years. During that time, standards have been developed in parallel to countries delivering a product, causing some consternation and difficulties. However, the industry and governments have stood strong, developing ISO 19794 standards for biometrics, ICAO standards for ePassports including Passive and Basic Access Control structures.
This has been the long awaited boost biometrics has been waiting for to a) raise its profile internationally and b) generate investment interest opportunities that can be realized by universities, research labs and the industry as a whole.
This talk will discuss the above in depth with significant reference to large scale projects akin ePassports, EU SIS II, EU BMS, Identity Cards, etc., and their impact on our livelihoods.
