Biometric verification is used to authorize the user by matching the features unique to every human being on earth. Features like a fingerprint, facial features, iris, and retina are used as biometrics to verify the identity. 

With the launch of face detection technology in smartphones, biometrics are becoming more popular but biometric as a form of verification is being used for a long time. As personal identification and authentication are becoming more important so does the use of biometric verification. 

From the identification of criminals to unlocking your smartphones, biometrics has come a long way. Many sectors in the world are using biometrics to identify and authenticate people.

Businesses consider that biometric verification is applicable to be used by government agencies only. But the use of biometric technology goes beyond these two. However, many sectors are recognizing that biometric authentication can help their businesses grow fast.

Different types of Biometric Verification

Before discussing the various uses of biometric verification, we will look at different types of biometrics.

Fingerprint Authentication: Fingerprint verification is the oldest form of biometric verification. To verify the identity of a person, fingerprints are matched against a database of already stored fingerprints.

Facial Recognition: A facial recognition technology uses the face feature captured through an image or a video. It matches the facial features with an already stored database of faces and verifies if the person is who they claim to be.

Iris and Retinal Scan: Probably the most promising use of biometrics, iris and retinal scan can be used as a source of verification. Different features of retina and iris are matched such as contraction and dilation of iris and retina and based on these traits identity of a person is verified.

After getting a thorough idea of types of biometric verification, let’s look at how it is transforming identity verification globally.

Airport Security

Blending science with security, biometric solutions are designed to change and complement the manual security systems. According to Forbes, almost 80% of the airports are considering using biometrics to reduce the discrepancies in manual checks. Some of the airports in the world are already using it and running the identity check smoothly. For instance, the US has implemented biometrics as a comprehensive terrorist screening measure in airports. 

Criminal Investigation

Biometrics are long being used by law enforcement agencies for criminal investigations. Today biometrics are widely used all over the world to identify the criminals. In 2008, China invented a system that scans fingerprints found on the crime scene against the database carrying inmates fingerprint data.

Online Transaction Authentication

Biometrics in online transactions has increased a great deal in the last few years. With an increase in online transactions and digital banking, the amount of financial fraud online also increased. To stop these frauds, the online financial sector has adopted biometrics as a tool for verifying the identity. 

Facial Recognition is not only time effective and cost-efficient but highly secure and convenient. It provides accurate results than any other form of verification. While aforementioned are the sectors using biometric technology for authentication. Biometric technology has a lot of potentials and can replace passwords and documents as a source of verification in the future. Experts predict that it will not only stop as an identity verification source a lot of undiscovered areas in our life will benefit from biometrics in the future.
