Biometric Fingerprint The Perfect Access Control Systems and How Biometric Fingerprint Recognition System Work

With crimes on the rise today, it becomes necessary to formulate a system which has a perfect security. A new system was therefore required to protect information of vital importance. One of the most efficient and the cheapest systems in place, the Biometric Finger Print Recognition System. Is a safe mode of storing and accessing vital information, data or any other business files. The fingerprint technology is used as every person has a unique set of fingerprints and none other can access the authorized account.

Biometrics is one of the modern units of security that companies today are employing all across the globe.They are fast replacing old fashioned security and authorization methods as they are indeed one of the best methods of identification in the globe. The older ones were pass cards, punch cards, passwords, etc, to help an employee into the building and authorize them into different departments.

Today no matter where you are or what you do, the Biometric Fingerprint Systems is one system that is activity to accomplish the activity of the employer, advisers and the HR aggregation absolute easy. Whether you are in Russia or Singapore, this is one system that has never bootless to accomplish the appropriate impact.

BioSecureID/Biometric Products is accepting acceptance as technology as able-bodied as appeal rises. This system has been put up in airports and added fields of claimed business area the complete database of a being is required. Such complete identification procedures are based on fingerprint identification, retina identification, geometry of the hand and finger and also the scent of a person.

The system may additionally be based on the voice, walking gait and typing rhythm. Amongst all these systems mentioned, , the fingerprint records system is the cheapest and the best calmly attainable systems. It is acclimated to admission some computer systems, accessible agent doors or alpha up the engine. The arrangement is additionally advantageous for gun accumulator and is additionally amount effective.The biometric fingerprint system works in an absorbing fashion.

By taking keen on account the workings of the system and the unique finger prints of a human body, the authorization system has come into existence. The fingerprint is fed into the system, and then a few seconds are taken in order to ensure that the right fingerprint is matched with the right authorization, and then it is finally read and validated. All this is done in a matter of seconds, by the Biometric fingerprint systems.

A recognition system is put in place where sensors read the fingerprints of the user and match it against the digital representation of fingerprints. When a match is found, various actions come into play. The processing is carried out in two phases and includes the establishment of an association and identification of a particular print to a particular person.

The system can take care of a single check or multiple ones, as need maybe. The entire process is fast and smooth. Once the data is fed into the system it is now possible to ensure that the right data is recorded and collaborated accordingly. It can be customized as required as well. Today as security threats and security breaches are done on a regular basis, it places even more pressure on the company to keep the company's data and their employees secure. This is why only authorizer personnel are let into the company after full authorization by the Biometric fingerprint systems.

There are two scanning systems of fingerprints that have been developed.

    Optical scanning system

A device that can read text or illustrations printed on paper and translate the information into a form the computer can use. A scanner works by digitizing an image -- dividing it into a grid of boxes and representing each box with either a zero or a one, depending on whether the box is filled in. (For color and gray scaling, the same principle applies, but each box is then represented by up to 24 bits.) The resulting matrix of bits, called a bit map, can then be stored in a file, displayed on a screen, and manipulated by programs.

Optical scanners do not distinguish text from illustrations; they represent all images as bit maps. Therefore, you cannot directly edit text that has been scanned. To edit text read by an optical scanner, you need an optical character recognition (OCR ) system to translate the image into ASCII characters. Most optical scanners sold today come with OCR packages.

Scanners differ from one another in the following respects:
scanning technology: Most scanners use charge-coupled device (CCD) arrays, which consist of tightly packed rows of light receptors that can detect variations in light intensity and frequency. The quality of the CCD array is probably the single most important factor affecting the quality of the scanner. Industry-strength drum scanners use a different technology that relies on a photomultiplier tube (PMT), but this type of scanner is much more expensive than the more common CCD -based scanners.
resolution: The denser the bit map, the higher the resolution. Typically, scanners support resolutions of from 72 to 600 dpi.
bit depth: The number of bits used to represent each pixel. The greater the bit depth, the more colors or grayscales can be represented. For example, a 24-bit color scanner can represent 2 to the 24th power (16.7 million) colors. Note, however, that a large color range is useless if the CCD arrays are capable of detecting only a small number of distinct colors.
size and shape: Some scanners are small hand-held devices that you move across the paper. These hand-held scanners are often called half-page scanners because they can only scan 2 to 5 inches at a time. Hand-held scanners are adequate for small pictures and photos, but they are difficult to use if you need to scan an entire page of text or graphics.

Larger scanners include machines into which you can feed sheets of paper. These are called sheet-fed scanners. Sheet-fed scanners are excellent for loose sheets of paper, but they are unable to handle bound documents.

A second type of large scanner, called a flatbed scanner, is like a photocopy machine. It consists of a board on which you lay books, magazines, and other documents that you want to scan.

Overhead scanners (also called copyboard scanners) look somewhat like overhead projectors. You place documents face-up on a scanning bed, and a small overhead tower moves across the page.

    Capacitance scanning system

A type of fingerprint scanner that requires a real fingerprint as opposed to a black and white image that would be used on an optical scanner. This type of scanner senses the fingerprint using electrical current instead of light, as optical scanners do and are said to me more secure as it is more difficult to forge a fingerprint on a capacitive scanner.

The Optical Scanning System utilized the CCD that finds wide application in camcorders, cameras, etc. A series of light sensitive diodes is present in the CCDs that produce a voltage according to the intensity of the illuminated light. Here the light signals that are reflected back from the palm and ridges of the fingers are converted to the electric signals, these electric signals are processed and compared with the ones stored and after that access is either granted or denied.

The working of the capacitance scanning system is a little bit complicated as compared to the optical scanning system. Here the CCDs are replaced by semiconductor chips and accommodate an arrangement of actual tiny beef which are smaller than even the width of the finger ridge. The biometric system uses authentic electric ability and the voltage aberration acquired by the ridges are candy and compared to the one stored central the arrangement and if a bout is begin again admission is accepted abroad denied.


Highlighting the above points, it is bright that the arrangement is added safe and defended and prevents exceptionable elements from entering into a place of high security. Thieves accept been balked in the acreage of actionable entry, fraudulence, bogus blueprint etc. However this can additionally advance to assertive malpractices as the person's basic advice can additionally be acclimated in places area a being has not consented to. Nevertheless, this arrangement ensures privacy, absoluteness and permanence.

You will find the system to be a simply working one, even though it is capable of holding in a lot of data and a lot of complex processes. This happens to be one of the best and most admired features of the system. And this is the reason why it can be well implemented into every single company, be it big or small. Since no two fingerprints can be alike, there is no chance that these Biometric fingerprint systems will go wrong.
