Biometric Authentication and Identification Systems Are Redefining Safety Standards

As the world is moving towards a highly interconnected digital ecosystem, various threats such as data breaches, unethical hacking, malware attacks, and other cybercrimes are increasing. Such concerning issues have compelled the government bodies and organizations to establish a highly secured system. The biometric authentication and identification system is one such technology that offers the most secure and reliable solutions against the cyber threats.

This technology is being adopted by nations across the globe. Several developed and developing countries have already established a mass identification program to identify their citizens and optimize their legal operations. Countries such as the U.S., Canada, Russia, France, Germany, the U.K., India, China, Japan, and Australia, among others, are adopting strong security technologies. 

What is a Biometric System?

The word biometric is made of two words: bio (human) and metric (measurement). In simpler terms, biometrics are related to unique human features that make each individual different from one another.

Biometric authentication and identification refer to the security system that involves the use of unique biological characteristics of individuals such as retinas, voices, facial characteristics, and fingerprints in order to verify the identity of people. This process is used to control access to physical and digital resources, such as buildings, rooms, and different devices. Integration of a biometric security system ensures a high level of safety and security of important resources.

The complete biometric system is broadly divided into two parts: Identification and Authentication.

Identification means, recording a person’s unique identity, while authentication means, verification of the identity that the person is claiming to be. Biometric identification verifies the person’s identity based on body measurements. Biometric authentication goes one step further and uses that information to compare the identity against a database and enters the information into service.

According to the BIS research market report, the global biometric authentication and identification market is estimated to reach $8.79 billion in 2026, at a compound annual growth rate (CAGR) of 16.30% during the forecast period 2021-2026.

How Does the Biometric Authentication Work? 

The process of biometric authentication and identification works by capturing, processing, and measuring the individual’s characteristics electronically and comparing the collected data with existing data. For instance, in a corporate organization, the officials upload the employee data to the security system at once, and then the employees verify their identities every day through different kinds of scanners while entering and exiting the premise every day.

There are various biometric scanning devices available in the market such as fingerprint scanners, retina scanners, iris scanners, speech recognition, facial recognition, behaviour identifiers etc.

Application of Biometric Security Systems in Various Industries 

Biometric security systems have many applications in various fields such as the legal sector, government sector, and commercial sector to secure important data. The following domains use biometric solutions for their respective necessities:

Legal sector applications:

Justice and law enforcement: In the legal sector biometrics technology is mainly used by the police and military officials to secure classified legal documents and offices. Fingerprint, face, and voice recognitions play a unique role in improving public safety and keeping track of the people who are on the radar of the judiciary system.

Government sector applications:

Border control and airport:  Biometric technology helps to automate the process of border crossing. Reliable and automated passenger screening initiatives help to facilitate the international passenger travel experience while improving the efficiency of government agencies and keeping borders safe from illegal breaching.

Healthcare: In the healthcare field, biometrics help in securing essential medical records that are valuable personal records of the patients. Lack of security and good accounting can make the difference between timely and accurate diagnosis and health fraud.

Commercial sector applications:

Security: biometric technology is being widely used in large corporations as well as small organizations in the commercial sector. Various biometric devices are used to secure the office premises as well as important products, designs, and documents.

Finance: The use of biometric identification and authentication in commerce helps make banking, purchasing, and account management safer and more convenient. For instance, in the banks, biometric solutions help to ensure the customer’s identity matches with the already existing data while accessing sensitive financial data.

Banking solutions and the payment technologies available today use a wide range of biometric modalities: fingerprints, iris, voice, face, fingerprint, palm veins, behavior, and other types of biometric recognition are all used alone or combined in a multifactorial manner as a system, to lock accounts and serve against fraud.

Mobile: The security of personal devices such as smartphones, tablets, and other types of handheld/ wearable devices is a concern for everyone.  Hence, we are witnessing a wide use of biometric technology integrated with our devices such as fingerprints, face recognition and voice recognition.


The need and demand for biometric authentication and identification technology are apparent in the market. Moving forward, with more advancements in technology, Companies are exploring possibilities of cloud computing and cloud storage to reduce the overall operation cost while offering consumers with desired security measures. Reduced reliability on hardware and increasing maturity, operational capability, and accuracy of software will define the growth areas of the market.
