Biometric Security Technology Types and Trends In 2021


Biometrics security seeks to address this problem by tying proof-of-identity to our bodies and patterns of behaviour.

Many personal and corporate security systems are incorporating biometrics as an advanced layer. This may appear infallible because of the unique identifiers in your genetics and behaviour. However, the adoption of biometric identity as a stand-alone authentication method has caused some concern.

Traditional passwords have long been a point of weakness for security systems, and modern cybersecurity is focused on lowering risks for this strong security solution. Biometrics attempts to address this problem by tying proof-of-identity to our bodies and patterns of behaviour.

Three Types of Biometrics Security

While biometrics can be used for various purposes, they are most commonly utilised in security. Biometrics are divided into three categories:

1. Genetic and molecular features are used in biological biometrics. These could include things like your DNA or blood, which could be analysed using a sample of your bodily fluids.

2. Morphological biometrics are concerned with your body’s structure. More bodily characteristics, such as your eye, fingerprint, or face shape, can be mapped to be used with security scanners.

3. Behavioural biometrics are based on patterns that are specific to each individual. If your walking, speaking, or typing behaviours are monitored, they can reveal information about your identity.


Because biometric technologies can be used to prove the buyer’s identity, mobile payments are regarded more secure than card payments.


One of the most important biometric trends in worldwide Internet banking is the use of biometric data to identify users (facial recognition and retinal scans, in particular).


Biometric passenger identification systems have emerged as one of the most important technology advancements at airports, customs, and other checkpoints around the world. For passenger boarding and baggage check-in, face recognition technologies and fingerprints are used.


Biometric data is being used more and more for border control and counter-terrorism. They can be used by law enforcement authorities to quickly and accurately identify a person.

Biometric technology is also used by authorities for forensic purposes. Biometrics are useful in forensic science because they allow you to identify someone and validate their involvement or non-involvement in a crime. It can disclose the link between a specific individual and a specific action, event, location, or another person prior to, during, or after a specific incident.


The biometric HR system delivers more accurate attendance data, decreases labour expenditures, and eliminates superfluous payroll costs. It also saves money by eliminating the need for an ID card and key fobs.
