Finger print scanning is a vital human identification process. Basically, it is automated technique of verifying an identity of an individual. Currently, there are high tech devices and methods applied in this verification process to authenticate individual’s identity.

Finger print Scanning Techniques

Some of the finger prints methods that are used to scan fingerprints in various parts within U.K are:

Optical Fingerprint Imaging

This technique involves scanning finger prints by a digital sensor. The sensor captures the digital image of the figure and relay a visual image of the finger print. The advantage of this technique is that it is not exposed to electrostatic damage. However, the draw back of this method is that the imaging process is affected by the texture of skin on the finger.

Algorithms Finger print verification technique

This procedure involves comparing an individual’s finger print with existed fingerprints templates. Ideally, there are two types of Algorithms fingerprint scanning there are pattern based and image based algorithms.

Capacitance finger print analysis

This mode of verification uses capacitance principles to formulate images of the finger prints. There are active and passive fingerprint scanning processes.

Biometric finger print identification technique

Currently, most of the criminal investigation, fraud, forensics and other institutes prefer this method as the best fingerprint scanning technique. This method involved analyzing the fingerprints of an individual against behavioral and physiological characteristic. It is one of the fingerprints scanning methods that are considered accurate. 

The scenario in finger print scanning has changed with emerging of efficient devices that are fast, accurate and convenient.
