A Review Of Multimodal Biometric Authentication Systems

Authentication is the process of validating the identity of a person based on certain input that the person provides. Authentication has become a major topic of research due to the increasing number of attacks on computer networks around the globe. This review paper focuses on multimodal biometric authentication systems in use today. The aim is to elicit the best combination of authentication factors for multimodal use. We study the strengths and weakness of selected biometric mechanisms and recommend novel solutions to include in multimodal biometric systems to improve on the current biometric drawbacks. We believe this paper will provide security researchers some useful insight whilst designing better biometric systems.
