Biometric Authentication System, Fingerprint, Retina, Voice, And Palm!

The biometric authentication system is the most advanced and most effective method of controlling access and security to a specific location, safe, or computer.

Thanks to the biometrics system, entering and exiting a building, accessing a computer, opening a safe, and even firing a gun is much safer and secure.

With so many biometric authentication products available on the market, it stands to reason that more and more homes will incorporate a biometrics authentication system for the purpose of protecting their valuables, their information, and their family.

Biometric Authentication Systems

There are 2 basic types of authentication being used:

Physiological authentication and identification involves physical traits that cannot be changed, meaning they cannot be forged either. Everyone has a unique pattern on their fingerprints, retina, palm, and DNA, meaning that only the person who matches those patterns can gain access to certain points.

Behavioral authentication and identification involves using everyone’s unique behavioral patterns to identify them. Everyone walks slightly different, writes in a different way, and types at a different rhythm and pressure. Using these behavioral patterns is more difficult, as these can be altered or falsified.

Modes of Operation

A biometric authentication system works in two ways:

Verification involves comparing the person trying to gain access to a location against an existing database stored in the software of the authentication device. The person is matched against the files in the database to determine if they are allowed to enter, exit, open, or gain access to the structure, and the devices react according to the information sent back from the database.

Identification is when a person’s unique biometric signature is first introduced into the database controlling the device. The unique pattern is stored in the database to be accessed at a later date.

Most Commonly Used Biometric Signatures

There are a few types of authentication signatures that are commonly used around the world:

The fingerprint is the most commonly used type of signature, and hundreds of different systems use them, including medical records, police records, and biometric access control systems. The fingerprint is the most convenient signature to use, as it is easily scanned within a couple of seconds.

The retina has a unique pattern that sets it apart from every other eye, and this is more commonly used for high security installations. The retinal scanning devices tend to be more inconvenient to use, as they require the eye be opened wide in order to scan the eye thoroughly.

The unique palm geometry and pattern of every person is often used to control access to certain locations, thanks to the fact that everyone has a palm of a slightly different shape. Palm scanners tend to be much more costly, so they are usually reserved only for those who want a high end system.

The voice print is usually used for the costlier locks as well, as the software required to capture, analyze, compare, process, and finally grant access to the voice print, tends to be much more expensive devices and much more complex as well.

The signature scanner is much less common, as it requires a very sensitive pressure plate.

Biometric gait verifiers require analysis of the way a person walks, and this can often be a much more faulty method of identification. After all, if someone comes to work limping, it may set off the alarms.

Today you can buy a biometric authentication system that use biometrics technology, including safes, locks, time clocks, and even scanner devices.
