A Review on Various Biometric Techniques, Its Features, Methods, Security Issues and Application Areas

Abstract

Biometrics is the emerging technology in the era of internet and mobile communication. The IoT revolution has enabled the things around us to communicate as it emerges as a smart system, hence security should be considered as primary issue as everything around us is going to be connected. Biometric Technology is considered to be the future of all electronic security which provides authentication and security management. This paper provides a detailed survey on existing biometric technology, different types of biometric traits, techniques adopted for feature extraction of various biometric traits and application areas of different biometric traits. The importance of biometric technology related to the various fields of security is also discussed through this paper. The biometric technology connected with smart systems helps in monitoring the human activities all over the world, thus providing a good security level. Biometrics acts as a major support to various fields of automobile security, Internet of Things (IOT) Security, health care security, workforce management of organization, government security, banking, and retail industry.
