A Comprehensive Approach on Different Biometric Modalities and Its Applications for Security

Abstract

Biometrics is an automated method of recognizing a person based on a physiological or behavioral appearance. Biometric detection technology relies upon the physical appearance of an individual, such as fingerprints, voiceprint, prototype of the iris of the eye and facial prototype, in identifying an individual, offering positive identification that is difficult to counterfeit. Instances of physiological biometric traits include height, weight, body odour, the aspect of the hand, the prototype of veins, retina or iris, the face and the prototypes on the skin of thumbs or fingers (fingerprints). Instances of behavioral biometrics are voice prototypes, signature and keystroke sequences and gait (the body movement while walking). Biometric identifiers are the distinctive, measurable appearances used to label and describe individuals [1]. Currently, passwords, Personal Identification cards are used for personal detection. However, cards can be stolen, and passwords and numbers can be guessed or forgotten. To solve these problems, biometric verification technology, which identifies people by their unique biological information, is attracting attention [2]. Biometrics is mostly used for authentication purposes to ensure proper safety.
