A Survey on Multimodal Biometrics Authentication and Template Protection

Biometric systems occupies a vast space in the field of security systems. Most of the applications make use of biometric systems such as attendance system, locker systems in banks, hospitals, industries, etc. Besides authentication provided by these biometric systems there is also need to protect the templates that are stored in them. This work involves a review of multiple biometrics such as fingerprint, face, hand vein, iris, signature, etc and the techniques used for authentication, fusion and template protection. Different traits and techniques are compared to obtain the most unique and suitable methods for biometric authentication and template protection. This paper also includes the comparison between the unimodal and multimodal biometric systems. Parameters such as Genuine Acceptance Rate(GAR), Equal Error Rate(EER) ,False Acceptance Rate(FAR) and False Reject Rate(FRR) are used to evaluate the various unimodal and multimodal biometric systems.
