Biometric security aims to address this problem by linking proof of identity to our bodies and behaviors.

Biometrics is emerging as an advanced layer for many personal and corporate security systems. With the unique identifiers of your biology and behaviors, it can seem foolproof. However, biometric identity has made many cautious about its use as stand-alone authentication.

Modern cybersecurity focuses on reducing risk for this powerful security solution: Traditional passwords have long been a weak point for security systems. Biometrics aims to address this problem by linking proof of identity to our bodies and behaviors.

Three types of biometric security

Although they can have other applications, biometrics have often been used in security matters, and you can mainly categorize biometrics into three groups:

1. Biological biometrics uses traits at the genetic and molecular level. These can include characteristics such as DNA or your blood, which can be assessed using a sample of your body’s fluids.

2. Morphological biometrics involves the structure of your body. Other physical traits such as your eyes, fingerprints, or the shape of your face can be mapped for use with security scanners.

3. Behavioral biometrics are based on patterns unique to each person. The way you walk, talk or even type on a keyboard can be an indication of your identity if these patterns are followed.

Trends in this technology


Mobile payments are considered to be more secure than card payments due to the possibility of using biometric technologies to confirm the identity of the buyer.


Biometric data used to identify users (facial recognition and retinal scans, in particular) is currently considered one of the vital biometric trends in global internet banking.


Biometric passenger identification systems have become one of the main technological innovations at airports, customs and other checkpoints around the world. Facial recognition technologies and fingerprints are used for passenger boarding and baggage check-in.


Biometric data is increasingly used for border control and counterterrorism purposes. They can be used by law enforcement to identify a person with a high degree of accuracy.

In addition, states are using biometric technology for forensic purposes. The use of biometrics in forensic science is useful because it helps identify a person and confirm their involvement or non-involvement in a particular crime. It can reveal the connection between a particular person and an action, event, place or other person before, during or after a particular incident.


The HR biometric solution provides more accurate attendance information, eliminates unnecessary labor costs and reduces labor costs. It also lowers operating costs by eliminating the need for an ID card or key fob.
