Biometrics technology comprises of automated systems that recognize a person based on an individuals unique physical characteristic. There are different types of biometric applications, but the basic premise is that the biometric must be based on a distinct human attribute such as a fingerprint, iris, voice or face patterns.
Fingerprint scanning is the most commonly used method used for biometric security systems. Fingerprint devices are the most commonly used systems that use biometric security. Uses range from high security environments to even household items like the fingerprint safe. The variety of systems available in the market is just overwhelming. The technology itself has evolved and the bulky scanners of yester years have given way to smaller, compact devices. They can now be even conveniently embedded into a laptop.
A fingerprint is actually a pattern that is composed of ridges, furrows, and unique characteristics than can be recognized at Minutiae points. Fingerprint authentication involves scanning the image captured on a sensor to identify a person based on these unique patterns. The sensor scans the fingerprint and then processes the pattern with the fingerprint database stored on the device. These devices come with software that helps compare and match the fingerprints with those in the database.
The fingerprint data that gets stored on the database is assigned a reference or PIN number that can then map to an individuals name or account or other defined parameters. This proves useful in that this allows not only for fingerprint authentication but can also be used to check access data or can even be used to export the data to a payroll system.
Biometric fingerprint readers are being increasingly used by large companies as also government organizations. Companies have realized that fingerprint authentication helps in easy employee identification and also enhances security. Data centers, for example, use biometric scanners to add an additional security layer.
While the cost of implementing large scale data centers are quite expensive, small offices and home users can find many fingerprint scanning devices that would fit into their budget. These products are designed to help you protect your hard drive, laptop, secure your valuables and most of all they allow the convenience of not having to deal with remembering multiple passwords.
