Biometric authentication is a highly advanced system for gaining accessibility and authenticating verification of people and premises. Using advanced computers and highly-developed recognition devices is the call of the hour. Several large corporate use this technology for accepting and denying access to people inside their premises. This technology is believed to be the future of digital authentication. Physical attributes and behavior of a person can be determined and checked to match with previously stored information to check the authenticity of a request. There are a lot of different options and methods available for biometric verification, which makes sure that an organization can find the exact device that it needs.

Different biometric authentication types

The most commonly used and easiest of all the methods is the fingerprint authentication. Every individual has their own fingerprints, which don’t match with any second person. The authentication device takes the fingerprint from a person and compares it with an already stored fingerprint to identify the person. This device is small in size and easy to access. Another very commonly used one is the voice recognition. This system determines the authentication of a person by matching the voice pattern of the person with the database of pre-recorded voice samples. This method requires that person to say a specific word or phrase in front of the recognition device.

One of the most complicated forms of biometric recognition is the facial recognition system. This system uses a device that comes with a camera. When a person stands in front of it, the camera takes a picture of the face and then maps different features of it, including size, shape, eye area, nose, cheekbone, ear and other aspects of the face. However, this device requires the person to have the same kind of face that is recorded in the database. That means, change of hairstyle, impact of stress and facial hair can make the device decline the authentication request, even if the request is genuine.

An advanced biometric identification method is eye recognition, and this process uses a lot of different aspects of a person’s eyes and what he or she does with it. That means the device records the eye blinking duration, eye shape, eye color and the patter of the pupil. Digital signature is also a commonly used biometric recognition process. For this, a person needs to sign on a specific device which has the ability to recognize the pattern, speed and pressure of the signature to authorize a request or a person.

ADVANTAGES OF BIOMETRIC AUTHENTICATION

These technologically advanced methods have a lot of great advantages. Emphasize on the physical attributes of a person by these devices, it becomes almost impossible to fake the identification of a person. There is no need to remember any identification code or password when it comes to using physical attributes. Using these attributes makes these devices hacking free, as even if they are hacked, replacing the data won’t be possible by the hacker. These advanced techniques work very complexly but they are easy to use. The biometric authentication systems keep private data secure and they are inaccessible without proper authentication.
