Biometrics involves the automatic, real time identification of individuals based on their physiology or behavior (Grant & Terry, 2012). Biometrics include a wide range of technologies that include facial recognition software, DNA profiling, voice recognition, fingerprint identification, and retinal scanning. The benefits of any technology are significantly dependent on the quality of the data base that are used to result in preventing crime. Facial recognition technologies can distinguish suspects and improve security and officer safety. Facial recognition is different from other biometric techniques that are used for surveillance purposes. Searching for wanted criminals, suspected terrorists, and missing children are benefits of the facial recognition seeing as it can be done from far away. This ensures that there is no contact with the subject and they remain unaware that they are being scanned. Fingerprint identification requires an individual to roll each finger across a fingerprint scanner. This typically takes several minutes and do not capture any other imprints of the hand, which are often found at crime scenes. Fingerprint identification is one of the most well known and publicized biometric. This is one of the most popular because it has numerous sources, the ten fingers, and the ease of access. The offender databases include offender photos, fingerprints that have been obtained, and images of distinguishing marks such as scars, tattoos, and other body modifications. The Automated Regional Justice Information System combines information from thirty-eight states, local, and federal law enforcement agencies all into one Website that can be accessed by registered police, court, and correctional officials. The Automated Regional Justice Information System also includes crime incident databases that are updated every twenty-four hours, most wanted

...Biometrics within Financial Institutions Abstract This paper presents a problem with the use of technology within the Credit Unions and Banking industries. Technological innovations have allowed the industry to be more open to consumers and challenges that the current economy has posed. Modern technology is also change the landscape of how, when and where business is conducted with financial institutions and consumers, businesses, and other organizations. Technology driven issues such as privacy, security and trust, have been pushed to the forefront, which makes the line between mobile banking and banking online increasing difficult to distinguish. Credit Unions like other banking institutions rely on gathering, processing, analyzing and providing information to meet the demands of the consumer. Given the importance of information systems within banking its not surprising to find, risks within the systems are developing in nature. History Truliant Federal Credit Union was started in Winston-Salem, North Carolina around 1952. They serve over 180,000 member owners and more than 900 business and organizations with $1.6 billion in assets.

...springer.com/chapter/10.1007/978-3-642-01793-3_20 Eigenvalue estimation plays an important role in biometrics. However, if the number of samples is limited, estimates are significantly biased. In this article we analyse the influence of this bias on the error rates of PCA/LDA based verification systems, using both synthetic data with realistic parameters and real biometric data. Results of bias correction in the verification systems differ considerable between synthetic data and real data: while the bias is responsible for a large part of classification errors in the synthetic facial data, compensation of the bias in real facial data leads only to marginal improvements. https://www.eff.org/wp/biometrics-whos-watching-you September 14, 2003 September 2003 Introduction Among the many reactions to the September 11 tragedy has been a renewed attention to biometrics. The federal government has led the way with its new concern about border control. Other proposals include the use of biometrics with ID cards and in airports, e.g. video surveillance enhanced by facial-recognition technology. The purpose of this document is to sketch out EFF's concerns about biometrics. In today's public arena, biometric technologies are being marketed as a "silver bullet" for terrorism; however, very little independent, objective scientific testing of biometrics has been done. Deploying biometric systems without sufficient attention to their dangers makes them likely to be used in a way dangerous...

...Title (2) Biometric scanning system types and which one is more effectiveness in a workplace Biometric recognition, or biometrics, refers to the automatic authentication of a person based on his or her physiological or behavioural characteristics (Jain, Bolle, and Pankanti 1999a; Maltoni, Maio, Jain, and Prabhakar 2003). One of the most important technologies which acts as a human being identify required purpose. Nowadays there were great progresses in technology of access for companies which it using human being body to identify the identity of the person. In the past Human beings used fingerprint to identity for signature. Biometric technology looks like a revolution for modern society for example, Iris and AFIS (Automatic Finger Print Identification System). Although fingerprint has a good feature to identify people but I will argue that iris system has shown the best performance to do the required purpose of scanning and identification more accurately than fingerprint. Reliability Fingerprint is a biometric device by which the people been identified through scanning fingerprint of the person and save the data to store the fingerprint image. Furthermore fingerprint identification scanning is reliability because fingerprint identification and authentication is the mature biometric technology (Komarinski, 2005). Firstly, the fingerprint is reliable because it includes quite huge information and will keep for all life of human being, In spite of the fingerprint just...

An accurate access control system is very important in domains like identification checks at airports, government organizations, FBI’s, scientific working groups like NASA, US defense department and driver’s license office. The main reason these organizations prefer Biometrics is because it measures physiological characteristics like fingerprints, iris patterns, facial recognition, retina recognition, ear recognition and DNA analysis. Based on the features of the biometric sensors used, the system can detect whether a person is an authorized user or not. Though there are many other methods for identification, biometric sensors are considered to be very reliable and accurate. The main objective of this paper is to build a fingerprint recognizer that is fully automatic and can minimize the errors caused while matching the fingerprints.

...What is a Biometric Time and Attendance System? Biometrics is the identification of people based upon their physical characteristics; most commonly their fingerprints, hands, eyes, or facial features. While time and attendance systems are used to manage employee attendance, scheduling, and associated payroll tasks. Within time and attendance, biometric devices are often used as a punch clock in order to add an extra layer of security, accountability and efficiency. How Does Biometric Time and Attendance Software Work? Step 1: Biometric Devices: Using biometric time and attendance systemsallows employees to clock in and out using their fingerprint, retinal scan, etc. Often times this process is also accompanied by a PIN (Personal Identification Number) which must also match the fingerprint or other scan. Step 2: Time and Attendance Software: Pairing your biometric device with a time and attendance software allows for more efficient payroll and attendance processing. Rather than spending hours adding up manually submitted clock-in and clock-out times, your biometric time and attendance software will allow you to automatically import data into your payroll software. This will significantly cut down on processing time and will eliminate errors derived from manually inputting information. Different Types of Biometric Devices Fingerprint Scanners are probably the most common type of biometric time and attendance device, simply because they are easy to use and are generally quite...

...Biometrics and finger/palm printing Tara Tatum Team C Introduction In many of the FBI’s high profile cases, one form of technology that has become highly effective is biometrics. The definition of biometrics is the science of measuring and statistically analyzing biological data. This scientific measuring tool is mostly used in identifying individuals whether anatomical or physiological. While fingerprinting is probably one of the oldest and most common forms of biometrics, other forms can include but are not limited to iris scans, voice recognition, palm prints, and facial recognition. As of late, the FBI, being a leader in the latest biometric technology, has created with the help of the science and technology branch, the Biometric Center of Excellence or BCOE. Not only has the BCOE strengthened the FBI’s abilities by proving the guilt, as well as the innocence of those convicted of crimes, but it has also been effective in thwarting terrorism that plagues many countries today. Finger/palm printing techniques Since the early 1920’s, fingerprinting techniques have been in existence, assisting in identifying and authenticating a person’s identity. This older form of biometric technology has both advantages and disadvantages. Some of the advantages can be the authentication of one’s identity, as no two person’s have the same prints, the cost effectiveness, the ease of use, the accuracy and the standardization. Some disadvantages are the intrusiveness, as some...

...already arrived in New York — but it’ll take a whole lot more than a new pair of peepers to trick this setup. An Israeli general is at work on a “biometric security” system that he believes will have New Yorkers tossing out their keys and maybe ditching their doormen, too. Using sophisticated scanners that can recognize a person’s face, voice, build and stride, the system can unlock your door in under two seconds. Any strangers not in the database will be denied access. “This is only the beginning,” says General Aharon Farkash, the founder and president of the firm FST21. “This is the way people will enter buildings in the 21st century.” To help establish FST21 in the states, Farkash opened a North American office earlier this month at 7 World Trade Center. Should you drop by, you’ll be greeted by one of its security devices. But unless he’s beamed a code to your phone or you work there already, there’s no convincing the small 8-inch scanner to let you in. The device looks simple on the outside, and in practice it is, essentially turning everyone into a human-size key. “Just like a fingerprint, we all look and act in a unique way,” Farkash says. “Biometric” technology has been around since the 1970s, and is often seen in thumb-print readers and retinal scanners. But thanks to less-invasive techniques, biometrics is starting to take off. “People have been talking about this for decades as the future, but I think the technology is finally good enough and invisible...

...Biometrics in Schools, Colleges and other Educational Institutions The following guidance has been prepared as an aid to schools, colleges and other educational institutions that may be considering the installation and use of a biometric system. This document is intended to encourage such institutions to fully consider if there is need for a biometric system in the first place and then to assess the privacy impact of different systems. The critical issues to be considered from a data protection perspective are the proportionality of introducing a biometric system and the requirement to obtain the signed consent of the student users (and their parents or guardians in the case of minors) giving them a clear and unambiguous right to opt out of the system without penalty. The document is not intended to promote any particular system, but is intended to make schools and colleges aware of their responsibilities under the Data Protection Acts 1988 & 2003. It is the use of a biometric system that may give rise to a data protection concern, not necessarily the production or sale of a system. All situations must be judged on a case-by-case basis. 1. Different types of Biometric systems All biometric systems operate on the basis of the automatic identification or authentication/verification of a person. What differs between systems is the nature of the biometric and the type of storage. 1.1 Information used to generate biometric data Biometric data may be created from physical or physiological...

...3-20-14 Biometric Scan Technologies This essay covers the basic history, importance, and impacts biometric technologies have on our security, and what the future may hold because of them. When speaking of biometrics, fingerprinting is usually the first biometric method most people consider. However, throughout the years, biometric technology has advanced and accrued new methods such as facial recognition and iris scanning. First off, we will discuss finger-scanning, or fingerprinting, as it is the oldest and most commonly used form of biometrics to date. This technology has always fascinated me because it identifies every individual based on their unique fingerprint, making it very difficult to replicate or bypass. An average scan can identify up to, but not limited to, 40 unique characteristics called “minutiae” a term coined by the FBI years ago. If that is the current ability of a fingerprint scanner, I can only imagine that in the future this method of biometrics will be the standard for consumer securities. Homes will have touch pads instead of keys, making the likeliness of a burglary slim to none. So, in the future fingerprinting won’t be limited for the elite and three letter agencies. Secondly, facial recognition biometric technology is gaining popularity, especially in modern social devices such as smart phones, tablets, and laptops. Although this method has much higher goals, it currently stands as an efficient means of security. Again, biometrics has always...

...Biometrics 125 years ago, winter 1879, Paris First agency police prefecture clerk Alphonse Bertillion was sitting in dark cold corner of huge file-cabinet room, where there were stored files on all Parisian criminals. A.Bertillion was entering the criminals’ description. He found out that there is no classification system, since: a) Criminals could easily change their names, and attempts to try different systems (by age, criminal method) end up in failure. Bertillion, son of Lui Bertillion – president of the Anthropological society, came up with an idea to utilize anthropological parameters (height, length and volume of the head, length of the hands, fingers, etc.) to identify personality. This was a break-through in criminalistics. With the development of electronics, Bertillioon’s theory was recalled and scientists realized that human beings have numerous unique characteristics beginning from the iris of the eye to the fingerprints and all these characteristics can be used in personality identification. With the rapid development of computer technologies, the concept of information security is becoming more and more important. Crime scene investigators have been using behavioral and physical characteristics for centuries in order to identify the criminals, nowadays; we have a great need for identification and authorization in information security. Information Security is being understood as a protection of the information and informational infrastructure...

...Biometrics is a unique and effective security technology that authenticates a person’s identity by verifying personal characteristics. Biometric devices grant users access to programs, systems, or rooms by analyzing some biometric identifier, such as a fingerprint or eye pattern. Two commonly used types of biometric security devices are fingerprint readers and iris recognition systems. A fingerprint reader captures the curves and indentations of a fingerprint. Fingerprint readers can be set up to perform different functions for different fingers. For example, the index finger could start a program, and the ring finger could shut down the computer [ (Jenkins) ]. Fingerprint readers usually cost less than $100, making it easy for people to use them in personal and business environments. Newer computer models include internal fingerprint readers for added security. External fingerprint readers usually are connected to a USB port on the computer [ (Parlor) ]. A biometric security device used in high security areas is an iris recognition system. Iris recognition systems read patterns in the iris of the eye. These patterns are as unique as a fingerprint. Iris recognition systems are quite expensive and are used by government security organizations, the military, and financial institutions that deal with highly sensitive data [ (Doe) ]. Biometric technology is a very effective way to keep information secure. Biometric technology is used in several different ways. Two widely known...
