Fingerprint recognition

What is fingerprint?
         Fingerprint is defined as the distinctive patterns which are formed by the valleys and ridges which are exist on fingertips. These patterns are restored if the fingertips are exposed to injuries, cuts and burns but these accidents can damage the quality of these fingertips. Fingerprint is unique for every person so It's impossible to find that two persons have the same fingerprint. Fingerprints are used widely in law for solving crimes.
Now, companies and organizations develop automatic fingerprint recognition systems. Examples such as mobile phones and computers equipped with fingerprint sensing devices for fingerprint based
password protection are being produced to replace ordinary password protection methods. Fingerprints have a wide range of applications and are used in many fields all over the world.

Fingerprint recognition
         The first discovery of fingerprint matching was by Sir Francis Galton in 1888. He said that fingerprints don't change over the time so they can be used for recognizing if the tow fingerprints are for the same person or not. The fingerprint consists of two important minutiae which are called termination and bifurcation. The termination part is the ending of a ridge but bifurcation part is the point from which two branches derive.
         Two indexes are well accepted to determine the performance of a fingerprint recognition system: one is FRR (false rejection rate) and the other is FAR (false acceptance rate). FAR-describes the number of times, someone is inaccurately positively matched. FRR- derives the number of times, someone who should be identified positively is instead rejected.  

Fingerprint Recognition Applications
§  Biometric Security: Fingerprint recognition is applied in biometric security for the protection of very important things as the old methods are not strong enough for the process of protection. Biometric technology can provide an enhanced security to anything you need to protect from small things to large things.
§  Airports: With fingerprint recognition, borders became safer than before. It helps in making the travel experience easier on passengers and also more efficient than before.
§  Financial Biometrics: It's used widely in financial field for making the management of banking safer by identifying and verifying commerce needs. Fingerprint recognition is used for accessing sensitive financial data and payment solutions in banks today.
§  Fingerprint Biometric Locks: The fingerprint is a unique thing which differs from one person to another so, you can use it for saving things which are valuable for you by fingerprint biometric lock which can also be used for the protection of houses by keeping doors closed.
§   Law Enforcement Biometrics: Fingerprint recognition plays an important role in recognizing wanted persons by law in addition to enhancing public safety.  
§  Mobile Biometric Technology: Fingerprint recognition is one of the most important techniques which is used in smartphones, computers, laptops or any devices for the security of these devices.
         Fingerprint recognition has other applications which are utilized in different fields such as physical access control, logical access control, healthcare biometrics and is widely used in biometric time and attendance solutions which is used in all organizations these days.
