Biometrics

Biometrics are forms of identification which rely on the physical characteristics of a person to prove who they are. Thumbprint scanners, retinal scanners, and voiceprint recognizers are all computerized forms of biometric authentication. Questions about these devices and other biometric techniques belong here.

What is facial recognition?

Facial recognition is a process for biometric verification. It can mean many things depending on its purpose, however, in most cases, companies are using it to verify individuals. Consider it an additional form of fingerprint recognition. You can easily unlock phones without touching it due to its camera recognizing the face. Also, many banks and websites are using this to ensure that only authorized personnel get access to their online portals. And lastly, it is being used for security at the entrance and exit of restricted premises.

What are the problem of using biometrics door lock system?

1. It takes time for one person to enter the door with a biometric reader. Fingerprint account is usually combined with a users card, and iris recognition also takes time, so the main question is, how many people use that door per minute.

2. Fingerprint is recognized by the number of matching minutiae (http://en.wikipedia.org/wiki/Fingerprint_recognition), and the result of each reading is a certain number, that varies as a result of temperature, humidity, user behavior, etc.
You got to find a fine compromise between having a secure scanner, and not making a queue at the door.


If the access system is too tough on users, they will seek a way to bend the rules, by leaving the door open, or giving pass for more people at the same time.

What are biometric devices and what is the difference between biometric scanners and biometric devices?

Broadly, a "biometric device" is any device that measures a biological function or trait. As related to computers, biometric devices are used to control access and/or verify identity. Voice recognition, retinal scanners, palm/fingerprint scanners are all examples of biometric devices. A biometric scanner will take a picture (your fingerprint, your retina) and match it to a previous scan kept on file. Other types of biometric devices, such as voice recognition systems, will record your voice and compare the recording to a sample on file.

What methodology can be used to accomplish biometric objectives?

Biometrics refers to the identification of humans by their characteristics or traits.

Biometric identifiers are often categorized as physiological or behavioral characteristics.

Fingerprints, face recognition, DNA, Palm prints, hand geometry, iris recognition, retina and scent are examples of physiological characteristics.

Behavioral characteristics (behaviometrics to some researchers) are related to the pattern of behavior of a person, and includes typing rhythm, gait, and voice.

To accomplish biometric objectives, methods such as requiring your fingerprint to be on credit cards or even requiring it to be scanned for purchases, use of voice recognition devices, or collecting your DNA can be used. However, there are privacy concerns about using these methods.

What is the conclusion of Keystroke dynamics as a biometric for authentication?

It is behavioral biometric. It is used to describe how an individualaddresses the keys on the keyboard. As biometrics go, it has a great price to performance ratio, as it is software only, requiring no special hardware. Purely based on accuracy, it is slightly less accurate than low end fingerprint readers, when comparing crossover error rate.

What is biometric ATM?

We all know of ATM's that accept our credit/debit card and the PIN number to dispense cash.

Biometric ATM's are the latest inventions to help us avoid fraud and duplication. If somebody steals our card and also knows our PIN they can easily withdraw cash from our account. In case of biometric ATM's they cannot.

Usually the PIN for bio ATM's is the finger print of the card holder or his eye retina scan etc. These cannot be duplicated and hence they are very safe and secure.

But they are very costly when compared to traditional ATM machines and hence they are not very widely used now.

Are biometrics good for society or just another step towards an Orwellian future?

Concern exists by some religions regarding biometrics, however we should examine the fact that we gradually have been creating ourselves as cyborgs (part machine) for quite sometime. Even metal teeth fillings are not natural along with artificial hips, bones, hearts, etc. Technology is inevitable as the adage of climbing Mt. Everest "because it exists." Still preservation of life should be the priority. If that is the motive and not profit, we might be headed in the right direction. I suppose Soul could live in a machine as well as a physical body (See Star Trek). The problem remains that biology is the natural state of man's evolution (albeit the subject is being attacked again by foolish naive creationists mainly because science is complex and scripture is poetry and not science. No complex calculus math equations are seen in religious scripture, i.e., theory of relativity, celestial mechanics, Fibonacci sequence [golden mean or phi ratio - Tesla's Wardencliff tower is the 1.625 ratio or the square root of 5-1 divided by 2], etc.), and not the potential of him becoming a machine. Always the potential is the problem in any science.

What are the disadvantages and advantages of biometrics?

The advantages of biometrics are the person is the key so you need never remember your card or key again. Each body part is unique and Biometrics uses your unique identity to enable a purchase activate something or unlock something. Biometrics encompasses Voice, Vein, Eye, Fingerprint, Facial recognition and more.

The disadvantages are numerous however: criminals have been known to remove fingers to open biometric locks, Biometrics requires a lot of data to be kept on a person, these systems are not always reliable as human beings change over time if you are ill; eyes puffy, voice hoarse or your fingers are rough from laboring for example it maybe more difficult for the machinery to identify you accurately. Every time you use Biometrics you are being tracked by a database bringing up a range of privacy issues. The final disadvantage is the expense and technical complexity of such systems. Disadvantages of a biometric system. * The finger print of those people working in Chemical industries are often affected. Therefore these companies should not use the finger print mode of authentication. * It is found that with age, the voice of a person differs. Also when the person has flu or throat infection the voice changes or if there there are too much noise in the environment this method maynot authenticate correctly. Therefore this method of verification is not workable all the time * For people affected with diabetes, the eyes get affected resulting in differences. * Biometrics is an expensive security solution. * Advantages of Biometrics :

* Increase security - Provide a convenient and low-cost additional tier of security.

* Reduce fraud by employing hard-to-forge technologies and materials. For e.g.Minimise the opportunity for ID fraud, buddy punching.

* Eliminate problems caused by lost IDs or forgotten passwords by using physiological attributes. For e.g. Prevent unauthorised use of lost, stolen or "borrowed" ID cards.

* Reduce password administration costs.

* Replace hard-to-remember passwords which may be shared or observed.

* Integrate a wide range of biometric solutions and technologies, customer applications and databases into a robust and scalable control solution for facility and network access

* Make it possible, automatically, to know WHO did WHAT, WHERE and WHEN!

* Offer significant cost savings or increasing ROI in areas such as Loss Prevention or Time & Attendance.

* Unequivocally link an individual to a transaction or event.

What is a Biometric ID card?

A biometric ID card is a card with some of a person's biometric information stored on it in electronic form. Biometric information generally falls into two categories - physical characteristics and behavioral characteristics. Typical physical characteristics include retina patterns, fingerprints, facial features, DNA, or body dimensions. Behavioral characteristics include rhythm and pressure when typing on a keyboard, handwriting, or vocal patterns (although vocal patterns can also be partly physical). A few countries are looking to incorporate biometric information into passports. Others are already working to issue residents new identity cards that have some of their biometric information embedded electronically. Special readers are required to retrieve the information from the card and when well designed, the reader may only translate the biometrics of the person presenting the ID into a hash which is then compared with the hash of the corresponding information on the card.

What is physiological biometrics?

Biometrics can be divided into two broad categories: physiological and behavioral. Behavioural biometrics are based on (hopefully) unique ways people do things such as walking, talking, signing their name, or typing on a keyboard (speed, rhythm, pressure on the keys, etc). By contrast, physiological biometrics are based on a person's physical characteristics which are assumed to be relatively unchanging such as fingerprintss, iris patterns, retina paterns, facial features, palm prints, or hand geometry. We all use a form of physiological biometrics when we recognize our friends and aquaintances. You know what they look like and sound like so you are usually able to recognize them when you see them or hear them. Turning those characteristics into reproducable electronic data is quite an art however and no perfect system has yet been developed that is absolutely foolproof - although some are pretty good.
