Biometrics

There are several biometric devices that do not require the person being identified to touch anything. Retinal and iris scanners do not necessarily require the person to touch anything. Facial recognition also usually does not require the individual to touch anything. The types of biometrics that require touching usually are focused on the hands or fingers or on something the hands or fingers do like keystroke patterns or signatures.

Yes, biometrics can be related to speech recognition. Speech recognition is a type of biometric technology that analyzes an individual's vocal patterns to identify them. By using speech as a biometric identifier, systems can verify a person's identity based on how they speak.

However we know that this is a time saving and useful for every company. Its main aim is to keep an eye on employees their login and logout.

Biometrics refers to the measurement and analysis of unique physical or behavioral characteristics like fingerprints or facial features for authentication or identification purposes. In today's society, biometrics is commonly used for access control to devices, buildings, or systems, as well as for verifying identities in security screenings such as at airports.

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.

At important places.

The Defense Biometrics Identification System (DBIDS) is a security program used by the U.S. Department of Defense to manage and control physical access to military installations and facilities. It uses biometric technology, such as fingerprints and facial recognition, to verify and authenticate the identity of individuals entering these locations.

Biometric devices have been traced as far back as 14th century China, where it was practiced in a form of fingerprinting used by merchants to distinguish children from one-another.

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.

Without an access control system, thieves could break into your building easier and steal your property or hurt the people in the building. If a criminal knows your building has weak security, it will be a much more likely target than a building that has a strong security system.

One of the best methods of building security is biometric access control. Biometric access control systems use finger print scanners to restrict access to the building or certain areas of the building so only those approved can enter.

its just info

They are used in airports, forensic science labs and police departments.They help tell the identity of different humans.

Biometrics is a very controversial subject. One of the main reasons it is disliked by some is because of the cost. There are some digital fingerprint reader for use that is $100. Another common concern is how a person's biometric, once collected, can be protected. People don't want their personal details in the the hand of the unauthorized owner, which can also lead to identity theft. Their information can be used in unauthorized ways without the person's permission. These are some of the reasons why Biometrics isn't that great

Precisely that

A fingerprinting scan is a very common biometric device. There are also iris matching scanners for high tech security. @Nottingham YE$

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.

1. Fingerprint.

Database,

A good way to keep your private data secure is GnuPG or PGP, which are encryption suites (google them to get more info)

I you are asking what the false-acceptance rates (FAR) are ... it depends on the type of biometric and how the sensitivity is set. The tighter you set the tolerances, the fewer false acceptances you get, but the more false rejections (FRR) you get.

Typically:

Fingerprint: 1% FAR at 10% FRR, 0.01% FAR at 20% FRR

Hand-print: Better than fingerprints - somewhere in the neighborhood of Retina scans

Iris: more intrusive but more accurate than retina scans

Retina: better than fingerprints, less than Iris. Affected by health - prone to false rejections when health changes

Voice: highly variable - affected by health (ever had a sore throat?)

Facial recognition: 1% FAR at 10% FRR, 0.01% FAR at 30% FRR

... of course there are other biometrics that can be used, there are just some examples and YMMV.

Usually Bio-metrics needs to be combined with another authentication method to achieve strong security - but with another method - even if the other method is a second bio-metric - it is very strong.

If you are asking a bout how secure the database of bio-metric information is... that's just a general question of how secure the computer system is. Improperly secured it would be a tasty target for an attacker seeing PII on individuals.
