Biometrics seeks to establish a users identity based on who she is rather what she possesses like an ID card or what she remembers like passwords. Biometrics gained popularity when body measurements were used by Alphonse Bertillon to identify criminals in the 19th century. It prompted law enforcer to take criminals fingerprints and store them in a database. The stored fingerprints could then be compared with fingerprints lifted from crime scenes. Biometrics are extensively used to identify criminals but has also gained use in employee clearance for sensitive jobs, determining fatherhood, forensics, identification of prisoners.
Performance – refers to the achievable recognition speed and accuracy, the resources to be used in achieving the desired recognition accuracy and speed and the environmental and operational factors that affect the accuracy and speed.
Different body parts are being used as a form of biometric recognition. Biometrics ranges from DNA matching, chemical biometric, visual biometric, eyes biometrics ( iris recognition, retina recognition ), finger geometry recognition, Hand geometry recognition, signature recognition and behavioral biometrics (typing recognition), vein recognition and gait.
Deoxyribonucleic acid (DNA) matching is the process used in the identification of persons by their DNA profiles. DNA profiles are hidden sets of numbers that reflect an individuals DNA composition, which can also be used as a persons identifier. DNA profiling is different from a full genome sequencing that is used in parental testing and criminal investigation. Even though 99.9% of human DNA sequences are similar in every person, unless they are identical (monozygotic) twins. DNA matching uses repetitive sequences that are highly variable, known as variable number tandem repeats (VNTRs), particularly ...Download file to see next pagesRead More

Computer Security and Biometrics

... of the of the 8 February Computer Security and Biometrics This paper illustrates the importance of information security management within the organization. The basic idea is to protect information, whether it is in the network, computer system or in a database. Likewise, for addressing system security, all the possible risks, threats and vulnerabilities must be identified for mitigation. Moreover, for authentication purposes, biometric systems are considered to be the most effective control that will also be addressed in this paper. Introduction Due to recurrent technological developments, information and communication technology frequently diverts in new dimensions. The research and development in the context of information... with goals...

...?Biometrics: Some Unseen Aspects Biometrics: Some Unseen Aspects Introduction Biometrics is the computerized method ortechnique of recognizing a person on the basis of physical or behavioral characteristics. Instead of the traditional security systems, the society today needs new verification systems to be in use; this is where the biometric authentication has gained its relevance. The production of biometric authentication systems has been increasing for the recent years. Numerous manufacturers and distributors have identified it as a growing industry. The technique has succeeded in preventing physical existence from highly protected environments. However the success of the method is still skeptical where network authentication... is...

...? Biometrics (Add (Add (Add Biometrics Biometrics is the ultramodern means of identification of individuals basedon their biological as well as behavioral characteristics. Biometrics had been a popular topic of debate for a while especially in choosing it as the technology for security checks and access control. As Jain, Bolle and Pankanti (n.d) point out, biometrics will gradually become a prime appurtenance in identification technology especially for the following reasons: repeatedly falling prices of biometric sensors, advancement in the underlying technology, increasing awareness among the public regarding the merits and demerits of...

Biometrics

... BIOMETRICS Introduction Biometrics refers to the unique personal, physical and measurable characteristics that can be used to identify an individual. The process involves both identification and verification of these traits. The identification process is different from the verification process in that verification involves comparison of the facial feature of a subject with the features of one other face to ascertain whether they match while identification involves comparison with several other faces to determine which of them accurately matches with the subject. There are various kinds of biometrics one of the most common being facial recognition. In facial recognition, the spatial geometry of the facial biometrics is recorded... . There are...

For instance, the history goes back to 1888 in which a French expert Alphonse Bertillon “Anthropometrics” who used fingerprints to distinguish between criminals and innocent public. However, after a century, technology of biometrics is still evolving and has become more...

...Running Head: BIOMETRICS AND WIRELESS TECHNOLOGIES Biometrics and Wireless Technologies of the of the Biometrics and Wireless Technologies Biometrics is the authentication or the identification of individuals based on a physical characteristic or trait. Physical characteristics include fingerprints, facial recognition, hand geometry or iris configuration; and traits include signature formation, keystroke patterns or voice recognition. Biometrics, as something you are, is both more convenient and more secure than something you know (passwords or pieces of personal information) or something you have (card keys, smart cards or tokens). There is no risk of...

Biometrics and Wireless Technology

...Biometrics and Wireless Technology We are living in a world where personal identification standards are rising higher and higher by the day. Biometric technology is fast becoming the identification process. It's processing is based on the unique physiological and behavioural characteristics that human beings possess. The term Biometrics specifically means measurement of living objects quantitatively (Miller 1994). Biometrics is one of many methods defined under Automatic Identification and Data Capture (AIDC) techniques (Biometrics: The Unique Identification of Human Characteristics). This technology is now the more favoured method of identification...

...Biometrics INTRODUCTION & DEFINITION Life measurement is the basic translation of the word biometrics that has been taken from the Greek language. Since the early twentieth century, statistical development has been the major concern of general science with the inclusion of field of biometrics. For instance, different varieties of wheat were compared with the help of different agricultural experiments, in order to understand the yielding characteristics of the wheat with the facilitation of statistical analyses through biometrics. In this way, a number of sectors have employed the means of biometrics for the determination of efficient methods meant for...

BIOMETRICS

...BIOMETRICS Information technology has revolutionized every aspect of our lives today. They have made our work simpler, fast and accurate. If we compare the technology of today to that of fifty years back, we will find that the advancements have surpassed the expectations of even the science fiction writers. The kind of technology and networking that exists around us has without doubt made life simpler for us. But, the extent to which it has made us safer is still being debated. While on the one hand we have advanced security gadgets, on the other the acts of sabotage too are being carried out in most sophisticated manner. Biometric technology is an effort to diagnose the problems and fill some of the...
