Fingerprint Identification Process


Biometrics is the automated system that can identify an human being by measuring their physical and behavioral uniqueness or patterns, and compare it to those on record. There are different types of biometrics which can identify fingerprints, face, iris, palm vein prints,voice of an individual.

Biometric broadly classify in two categories

1.Physiological characteristics: Physiological characteristics means shape of the body e.g it includes fingerprint, face recognition, Palm vein print, iris recognition and lot more

2.Behavioral characteristics : Behavioral characteristics are related to the behavior of a person, e,g typing rhythm,gait, and voice and lot more

Fingerprint Recognition process has been elaborated below:

A fingerprint scanner system has two aspects – It needs to get an image of your finger, and it needs to determine whether the pattern of ridges and valleys in this image matches the pattern of ridges and valleys with the registered fingerprint image.

Only special characteristics, which are unique to every fingerprint, are extracted and saved as an encrypted biometric code. Fingerprint image is not saved, only a series of numbers (a binary code), which is used for verification. The algorithm cannot be reconverted to an image, so there are no chances of creating duplicate fingerprints. (See Figure 1.0)

Advantages of Fingerprint Authentication:

  • High Speed authentication.
  • Highly accepted by the people.
  • Not easy to forge.
  • We can’t misplace fingerprint, like other non-biometric that we can misplace like access card.
  • Fingerprint authentication provides information like ” what you have ” , ” What you know ” , “Who you are “.
