The modern world is switching to being completely digital, with almost all activities possible online. We have to be aware, though, of the growing risk of identity theft. The need for secure and foolproof methods of identity verification has never been greater.
Fortunately, the technology is ready, as biometrics has a number of functions that can successfully be used to protect your bank account, phone, or even home from unauthorised access. What is biometrics and how is it used for identity registration?
What Is Biometrics?
Biometrics can be simply explained as the measurement and statistical analysis of a person’s physical and behavioural traits. Each individual has unique traits, which makes them an ideal tool for identity verification.
Complex biometrics systems capture and digitise these traits, convert them into data, and analyse them. The combination of physiological and behavioural features, ranging from fingerprints, facial features, iris patterns, and voiceprints to typing rhythms and gait patterns.
How Is Identity Registered?
The process of identity registration is quite complex, consisting of a few steps. The whole procedure starts with data collection, which takes place during the registration process. Special sensors or scanners collect the individual’s biometric data, such as facial features analysed by facial recognition cameras.
The data is then converted into digital format and transformed into a biometric template—a series of numbers and algorithms that encapsulate the individual’s unique traits. The data is securely stored in a database, forming the individual’s unique digital identity.
In cases where identity verification is required, the biometric system compares the presented biometric data with the stored template. When the presented data matches the stored template, then access is granted.
How Are Biometrics Used?
There are a few examples of successful use of biometrics for the purpose of identity verification.
#1 Access Control And Security
A lot of big companies have introduced biometrics to identify their employees, grant them access to specific areas, or check their working hours. Biometrics have been integrated into smartphones, laptops, and other devices to prevent unauthorised access and protect your data. Do you have to use your fingerprint or face recognition to start using your phone?
#2 Border Control
One of the most complex uses of biometrics is for border control. Airports and border checkpoints use a biometric enrollment system with official records of fingerprint scans and facial recognition to match travellers with their official records. The system helps reduce the risk of illegal immigration.
In a nutshell, biometrics have a number of functions, most of which are focused on the authorisation process. They are used in the financial sector for transactions and payments, patient identification to prevent medical errors, and welfare programs to make sure the subsidies are distributed to the rightful recipients.
