As technological advancements progress, our means of identification and authentication also continue to develop. Traditional methods such as passwords and PINs are becoming less secure, and hackers are finding new ways to exploit them. Biometric identity, on the other hand, is becoming increasingly popular as a more secure and convenient way to authenticate identities.

Biometric screening, biometric security, biometric passports, and biometric recognition are all part of the larger field of biometrics, which involves using physical or behavioural characteristics to identify individuals. In this article, we will take a deeper dive into these biometric identification methods and explore how they are changing the way we authenticate our identities.

Biometric Screening: Using Biometric Data to Verify Identity

Biometric screening refers to the process of using unique biological characteristics, such as fingerprints, facial features, or iris patterns, to authenticate or verify a person’s identity. Many uses for this exist, including border control, law enforcement, and even in the medical field. Travelers’ identities have traditionally been confirmed at crossings via biometric scanning. Other sections, like the check-in and boarding facilities at airports, are getting the technology as well.

The FBI’s Next Generation Identification (NGI) system’s face recognition capability, for example, allows for the comparison of a suspect’s photo to a database of known criminals.

Biometric screening has the potential to enhance the accuracy of patient identification in healthcare settings, which can help ensure that individuals receive appropriate treatment and care. For example, a patient’s fingerprints can be used to verify their identity before administering medication or performing a medical procedure.

Biometric Security: Using Biometric Data to Secure Access

Biometric security involves using biometric data to secure access to devices, systems, or physical locations. For example, a company might use biometric security to allow employees to access a restricted area or to log into their computers. 

Usage of Biometric security:

Physical access control: Using fingerprints or facial recognition to secure access to a building or room

Logical access control: Using biometric data to log into a computer or access a network

Transaction authentication: Using biometric data to authorise a financial transaction

One example of biometric security is Apple’s Face ID, which uses facial recognition to unlock an iPhone. Due to the fact that it is far more challenging to unlock an iPhone using a phoney face than it is to guess a password, the technology has received plaudits for both its simplicity and security.

Biometric Passports: Using Biometric Data to Verify Identity for Travel

Another example of how biometrics are being used to increase security is the inclusion of them in passports. With the help of facial recognition software or fingerprints, biometric passports can be used to confirm a person’s identity.

Using Biometric Information to Identify User

With biometric information, it is possible to recognise people even in huge groups. With facial recognition technology, for instance, one can locate a person in a crowd during a sporting event or concert.

Marketing and advertising can also make advantage of biometric recognition. For example, companies can use facial recognition technology to track customer demographics and behaviour, such as age and gender, to better target their advertising.

Digital Onboarding: Using Biometric Data to Simplify Authentication

Digital onboarding is the process of verifying a customer’s identity when they sign up for a new service, such as opening a bank account or applying for a credit card. Traditionally, this process involved filling out forms and providing identification documents, which could take days or even weeks.

Now, many companies are using biometric data to simplify the onboarding process. For example, customers can take a selfie and use facial recognition technology to verify their identity. Customers can finish the onboarding procedure quickly by doing this in real-time.

Biometric User Authentication: Using Biometric Data to Verify User Identity

Biometric user authentication involves using biometric data to verify a user’s identity when logging into a device or system. This is becoming more and more popular as a safer alternative to passwords, which are frequently stolen or easily cracked.

As an illustration, several smartphones now come equipped with biometric features like facial recognition or fingerprint scanning to unlock the device. This provides a more secure way to access personal information and make purchases on the device.


Biometric technology is transforming the way we verify our identities, providing a more convenient and secure alternative to traditional methods of authentication. From biometric screening and security to biometric passports and recognition, the benefits of biometric identity are clear. As we continue to rely more on technology, biometric identity will likely play an even larger role in how we verify our identities and access information.
