Understanding the technologies of fingerprint recognition


Understanding the technologies of fingerprint recognition is important. However, before knowing that, it is important to understand the different parts of a particular fingerprint. Generally, in simple terms, fingerprints are the patterns that the pores in your fingers are able to create. The elevated lines in your fingers are known as ridges, while the lowered parts, which are between the ridges are known as the valleys. The shapes on the ridges also have different names, such as the point where the ridge ends is known as an ending point. The ridge may also divide into two parts, and that particular point where it does so, is known as the bifurcation point. In addition, the other two points are known as the delta and core. Coe generally tends to have different directions, whereas the delta has ridges, which spreads in only three directions. Unless a person’s inner skin gets damaged, the fingerprints of a person do not need change, and it is within the inner skin that the fingerprints are formed.

The history of the fingerprint recognition has been there since 7000-6000 BC, and it has always been used for identification purposes in Assyria and China. It was used by porcelain makers in order for them to identify their assets much better. Eventually, this system has progressed to include many technologies, using these different kinds of fingerprint techniques. Fingerprint technology with the increase in the growth of communications in the 1990s became hugely popular for a wide range of different purposes.

Today, there are different kinds of fingerprint technologies. A famous one uses a sensor, consisting of a prism, a lens, a light source, as well as an acquisition device, in order to create an image of the fingerprint on the prism, which is delivered to the CCD. Whenever the machine gets any entry from a fingerprint, it reads it thoroughly using the ridges and lines, and then ‘matches’ it to the database of fingerprints already stored in the system. This is done by matching the similarity between the fingers.

This is usually the basic mechanism of fingerprint technology. It is widely used for security purposes, as well as to protect computers and restrict access into rooms or certain networks. Because of the recent advancements, this technology has become extremely cost-effective, as well as portable versions are also available now. The future of fingerprint technology is still booming, because it can be used in a variety of different areas, and it will ensure the reliability and safety of the workings of such areas.
