Multi modal Systems

Course Description

All of the biometric systems we’ve explored thus far have been unimodal, relying on a single source of information for authentication. Multimodal biometric systems, as the name implies, accept information from two or more biometric inputs.

Unimodal systems must cope with a variety of issues, such a lack of confidentiality, non-universality of samples, the extent of the user’s comfort and freedom while interacting with the system, spoofing attacks on stored data, and so on.

Multimodal biometric systems that integrate or fuse information at an early stage are thought to be more effective than systems that integrate information at a later level. The obvious reason for this is that the information in the early stage is more accurate than the matching scores of the comparison modules.
