The biometric authentication is really a highly developed process of monitoring and authenticating the identity of an individual with regards to the physical attributes and behavioral characteristics. With the emergence of complex computer technology and enhanced accuracy offered by different information collection devices, biometrics has gained immense popularity today, and it is popular in important business processes and organizations. Over the years; biometrics will essentially replace every other form of accessibility checks and identity tracking, ensuring improved security and monitoring system.

The Advantages:

Biometrics is among the most effective ways of identifying and confirming the identity and access profile of the person. Discussed herewith would be the key advantages of biometrics.

   Since authentication is based on the physical attributes and cognitive traits of the person, it is perhaps impossible to imitate it.
   The user needs to memorize it just like a password, and just the physical and behavioral traits are sufficient in confirming the identity.
   It can't be hacked under any situation, except the highly advanced technology systems. Since physical traits and behavioral attributes are unique towards the person, hacking or replication is rarely possible
   Biometric authentication is hassle free in nature, whereby the report could be generated instantly on the pc.
   Important details about the individual is recorded with respective biometric attributes, ensuring effective monitoring and control from time to time.
   Applications of biometrics include attendance tracking or authenticating option of a small area.

The other hand:

Because of certain flaws in biometric scanners and lack of anti-hacking mechanism, it is strongly recommended that biometric traits, along with some complex passwords, ought to be utilized in confirming the identity of a person. This prevents the chance of decoding the biometric patterns, which is often possible with false equipments.

Types of Biometric Authentication:

Mentioned here are a few from the important types of biometric authentication.

Fingerprint Recognition - This is actually the most commonly used biometrics, today. Fingerprints are unique to each person, and based on this idea, fingerprints are used in verifying and confirming the identity or access of a person according to pre-stored fingerprint marks. The system can be simply accessed and want a small space to install.

Voice Recognition - This is different from speech recognition. With this particular biometric authentication method, the identity of the individual is verified based on a specific voice pattern that is pre-recorded, and not any particular statement.

Eye Scan - In this system, the eye of the person is scanned to authenticate access profile and identity that cannot be imitated easily. The system guarantees advanced security.

Facial Recognition - This method uses distinct facial expression in verifying a person, including cheekbone area, eye socket outlines, sides of mouth, and placement of nose and eyes.

Digital Signature - While not directly related to biometrics, this is a commonly used identity tracking mechanism that utilizes digital signature of the person to verify identity and access. However, the process is cumbersome and includes risks of hacking.

Irrespective of all drawbacks, it is expected that biometric authentication will emerge as the best identity tracking mechanism, ensuring advanced security and control in the a long time.
