Biometric Security Technology

Abstract

The word biometrics comes from the Greek words “bios” (life) and “metrikos” (measure). Strictly speaking, it refers to a science involving the statistical analysis of biological characteristics. Thus, we should refer to biometric recognition of people, as those security applications that analyze human characteristics for identity verification or identification. However, we will use the short term “biometrics” to refer to “biometric recognition of people”. Biometric recognition offers a promising approach for security applications, with some advantages over the classical methods, which depend on something you have (key, card, etc.), or something you know (password, PIN, etc.). A nice property of biometric traits is that they are based on something you are or something you do, so you do not need to remember anything neither to hold any token.

Performance Evaluation of Face Recognition system by Concatenation of Spatial and Transformation Domain Features

“…The term Biometric is mainly originated from Greek word Bio means life and metrikos means measure [1]. It authenticates the person depending on his/her unique features.…”

Hybrid Face recognition using Fusion of DTCWT and FDCT Features

“…As there is rapid growth in technologies like internet, cell phones and digital cameras, there requires increased demand on security since the communication between each users and between several organizations is rapidly increasing through the digital devices. Biometric [1] traits gains more importance because of its high recognition accuracy, resistant to spoofing attack, avoids inter class similarity, reduce intra class variations when compare to password or Personal Identification Number (PIN).Face recognitions has become one of the important biometric trait because of its vast range of applications like credit card, banking, security etc. Many biometric authentication system like iris, fingerprint, vein and DNA fingerprint systems suffers the problem of data acquisition.…”
