Comparative and Analysis Study of Biometric Systems

PIJMT, 2015

In the ever-changing world of global data communications, and fast-paced software development, security is becoming more and more of an issue. No system can ever be completely secure, all one can do is make it increasingly difficult for someone to compromise the system. The more secure the system is, the more intrusive the security becomes. One needs to decide where in this balancing act the system will still be usable and secure for the purposes. Here we have discussed different Biometric tools and related security issues. Identity is to establish the identity of a person, or to ascertain the origin, nature or definitive characteristics of a particular person. To uniquely identify a person different types of information can be used with other sources. This concept is ancient, and has become much more important as information technology and the Internet have made it easier to collect identifiable documents. To identify a person, the recent trend is to use biometric. Different biometric features can distinctively identify a person unless there are identical twins. In case of identical twins many biometrics fail to distinguish them as separate person, but fingerprint still can distinguish. In recent technology more than one biometric feature is also being used in a combination to have more robust indentifying system. Several research projects have shown that multimodal biometrics (e.g. fingerprints and voiceprints combined) can improve the performance and reliability of biometric authentication.

Biometric has taken from the Greek word "bios" meaning life, and "Metrikos" managing measurement and has introduced an Environmental Meter. A biometric system is essentially a pattern recognition system which recognizes a person based on special features, specific physiological or behavior vectors. The obtained feature vectors are stored in the database. Generally, a biometric system based on physiological characteristics has a high reliability. In this paper, we try to bring some of biometric identification techniques alongside their advantages and disadvantages.

Biometrics systems have come into existence from the birth of a human being in different forms, and measure physical characteristics. It differs from man to man and it provides a measurement of physical characteristics. The system speaks about all psychological characteristics considering the permanent identification of each and every person. Actually, these physical characteristics of a human being are permanent ones and do not change throughout life. This paper presents various biometrics techniques in the field of security and identification purposes. Each method covers a number of advantages in comparison to others. Although there are various biometric methods available, still there is a need to compare these methods in order to provide the best and efficient method.

Over the last few years a new area of engineering science has been established whose products are likely to create a large market in the near future. It has been called ''biometrics”. The pioneers of this new domain intend to construct devices which would allow identification of a person on the basis of his/her ''biological'' characteristics: voice, dynamics of movements, features of face and other parts of the body, retina or iris pattern. Nature has made human beings with different characteristics which may vary from one person to another. Biometric system is essentially a pattern recognition system which recognizes a user by determining the authenticity of a specific physiological or behavioral characteristic possessed by the user. Several important issues must be considered in designing a practical biometric system. First, a user must be enrolled in the system so that his biometric template can be captured. This template is securely stored in a central database or a smart card issued to the user. The template is retrieved when an individual needs to be identified. Depending on the context, a biometric system can operate either in verification (authentication) or an identification mode. This paper gives an overview of key biometric technologies and basic technique involved. The various opportunities for biometrics are mentioned, followed by the uses, benefits, and applications.

The term biometric comes from the Greek words bios (life) and metrikos (measure).Humans have used body characteristics such as face, voice, gait, etc. for thousands of years to recognize each other. With the proliferation of computers networks in our day to day life, the increased number of applications making use of such networks leads to a problem of identity theft [7] .A wide variety of systems requires reliable personal recognition schemes to either confirm or determine the identity of an individual. Biometric technology is more convenient and efficient than any other protection technologies used for identity authentication. Biometric technology plays a key role in recognizing humans based on their body Characteristics .The purpose of such schemes is to make sure that the rendered services are accessed only by a legitimate user, and not by anyone else. Hence Biometrics plays a vital role in securing one’s privacy using various Biometrics techniques through which fraudulence can be avoided. Biometric technology is considered one of the best protection methods of user information and data[8].

Biometric recognition refers to an automatic recognition of individuals based on a feature vector(s) derived from their physiological and/or behavioral characteristic. In order to deal with security, Authentication plays an important role. Biometric recognition systems should provide a reliable personal recognition schemes to either confirm or determine the identity of an individual. Applications of such a system include computer systems security, secure electronic banking, mobile phones, credit cards, secure access to buildings, health and social services. By using biometrics a person could be identified based on "who she/he is" rather than "what she/he has" (card, token, key) or "what she/he knows" (password, PIN). We have also outlined opinions about the usability of biometric authentication systems, limitation, comparison between different techniques and their advantages and disadvantages in this paper. Present study deals with new innovative model ...

The term biometrics is derived from the Greek words bio meaning “life” and metrics meaning “ to measure” . Biometrics refers to the identification or verification of a person based on his/her physiological and/or behavioral characteristics. Several verification/identification based biometrics have evolved based on various unique aspects of human body, ease of acquiring the biometric, public acceptance and the degree of security required. This paper presents an overview of various biometrics in use/proposed and their applicability to different activities.

Biometrics is a field of science which deals with the positive identification of unique individuals based on their physiological or behavioural characteristics. Biometrics has lately been receiving attention in technologies. In today's world the need for large-scale identity management system, whose functionality relies on the accuracy of identifying individuals influenced the development of biometrics in modern world. This paper discusses about Biometriccharacteristics in detail. The demerits of unimodel biometric and the characteristic of Multimodel Biometrics are also described. And finally, the biometric security issue is touched and the various levels at which a particular biometric system can be attacked is presented.

— Biometrics is becoming very essential in computer security world. Biometrics refers to an automated system that can identify a person by measuring their physical and behavioral uniqueness or patterns, and comparing it. By using biometric techniques a person can be identified/verified based on " who she/he is " rather than " what she/he has " (card, token, key) or " what she/he/ knows " (password, PIN). In this paper, present a review of biometric standards, both unique and multi model, and their advantages and disadvantages will be presented.
