What is Biometrics? From Your Fingerprints to Digital Identity

Biometrics? We all use it every day - from the moment we wake up until the moment we go to sleep. We use it to unlock our phones, access secure facilities, and even make online purchases. But what is biometrics and why is it so important?

In this blog post, we'll explore the world of biometrics and how it's changing the way we live and work. Through a deep dive into its applications, implications, and emerging trends in the digital world, you'll be sure to gain a better understanding of biometrics and how it's transforming the way we interact with technology.

🧐 What is Biometrics?

Biometrics refers to the scientific practice of measuring and analyzing an individual's physiological or behavioral characteristics to identify, verify, or authenticate their identity.

Some of the most commonly used biometric identifiers nowadays are fingerprints, faces, voice, iris, gait, and hand geometry.

The Types of Biometric Identifiers

Biometrics are categorized into two distinct sets below based on their inherent or learned attributes:

1) Physiological biometric identifiers:

Physiological biometric identifiers are characteristics that you’re born with, such as fingerprint, face, iris, palm vein, palm print, hand geometry, and DNA. These are physical characteristics that don’t change over time and are unique to each individual, making them the most common type of biometrics used in today's world due to their high accuracy and reliability. Listed below are some widely used physiological biometric identifiers for authentication and identification:


The fingerprint is widely acknowledged as one of the most reliable and widely used biometric characteristics in our daily lives. Our fingerprint patterns are formed while we're still in the womb and continue to stay unchanged throughout our lifetime. This remarkable feature has made fingerprints a primary choice for applications that require secure identification and authentication.

With sophisticated fingerprint sensing technologies, our fingerprints can now be conveniently captured in no time at all, making fingerprint recognition a cost-efficient and reliable solution for biometric identification and authentication across many applications.


Your face is a unique combination of facial features and expressions that can easily be used for authentication purposes. Nowadays, face recognition technologies are becoming more and more popular as they're capable of recognizing a person's face in no time at all, even in challenging environments and low-light conditions.

Face recognition technology has seen widespread adoption in a wide range of applications, from unlocking phones to providing physical access control and surveillance in banks, schools, airports, and retail stores. As facial recognition software and 2D, 3D, and thermal imaging sensing technologies continue to advance at a rapid rate, the accuracy of facial recognition systems is becoming more trustworthy.


The iris is the colored portion of the eye that contains several unique patterns, making it a reliable biometric characteristic. With its higher accuracy and immunity to environmental factors, such as aging and fatigue, the iris is a much sought-after biometric for authentication.

Iris recognition technology utilizes advanced cameras with invisible infrared light and sophisticated image processing algorithms that accurately capture iris scans for a variety of applications. It's now being utilized in banking, law enforcement, border control, etc. to provide extra security measures.


The retina is the innermost layer of the eye and contains a person's unique blood vessel pattern. Retina scanning technology uses a low-intensity beam of light to capture a high-resolution image of the eye, which is then compared against a reference database.

Retina scanning technology is a reliable biometric characteristic, as the pattern of blood vessels in a person's eye remains unchanged over time. This technology is now being used for high-level security applications, such as granting access to secure data centers or nuclear power plants.


Vein recognition technology uses near-infrared light to detect the pattern of veins in a person’s finger, palm, or eye, making it a reliable biometric characteristic for authentication. The vein/blood vessel patterns are unique to each person and remain unchanged over time, making them difficult to forge or imitate.

As vein recognition technology evolves, finger vein recognition and palm vein recognition are two of its primary applications. From financial services to medical care, these technologies have been adopted by a host of industries. Eye vein recognition technology is relatively new in the market, and it's being used for unlocking mobile devices.

Hand Geometry

Hand geometry is an old form of biometric data and involves making use of the physical features that make individuals unique, such as their hand size and shape. This technology involves measuring specific attributes across an individual's palm or fingers to verify identity with accuracy. Finger width, palm length, and finger length are just some examples of elements that can be used in this process for identification purposes.

Although hand geometry is not as accurate as other biometric technologies, its low cost and ease of use make it a suitable choice for certain applications. It is commonly used in time and attendance systems and access control systems.

Palm Print

Palm print is unique patterns to each individual and can be used in biometric authentication systems with great accuracy. Cameras are used in palm print technologies to capture a high-resolution image of the palm, which is then processed by algorithms to extract and match unique features such as the palm's lines, ridges, and creases.

This technology typically produces a pattern that is very difficult to forge or imitate, making it a reliable biometric characteristic. Palm print biometric technology is now being used in the banking and healthcare sectors, as well as public safety and law enforcement.


The heartbeat biometrics system is one of the most cutting-edge forms of biometric identification and authentication. This technology is based on a person's unique electrocardiogram (ECG or EKG) signature, which is acquired using a device that picks up the electrical signals generated by the heart.

However, heartbeat biometrics technology is still in its infancy and yet to be adopted widely. There're several limitations including the need for users to remain still and the lack of accuracy when it comes to recognizing heartbeats in noisy environments. Nevertheless, the potential of this system cannot be overlooked as it could eventually provide additional layers of security in sectors such as banking and healthcare.


DNA is the most unique biometric characteristic and can be used to identify individuals in a very accurate manner. DNA is the genetic material inherited from one's parents and is unique to each individual, making it virtually impossible to forge or imitate. It can be extracted from a person's saliva, blood, hair, or other body tissues and then compared against known samples to verify identity.

However, this technology has a number of major drawbacks including its high cost, its invasive nature, and the fact that it has a limited range of applications. Additionally, DNA analysis requires specialized training and expensive equipment, and the process can take several days or longer to complete. The applications of DNA biometrics are largely limited to forensics and law enforcement.

2) Behavioral biometric identifiers:

Unlike physiological biometric identifiers, behavioral biometric identifiers are related to the way you act or move. These identifiers are learned over time and include keystroke dynamics, mouse dynamics, gait patterns, signatures, and voices, among others. Although behavioral biometrics may not be as accurate or reliable as physiological biometrics since they can potentially be affected by stress, fatigue, illness, or the environment, they are still used in particular areas like banking and healthcare. Listed below are some of the most commonly used behavioral biometric identifiers:


Voice recognition technology uses audio patterns to authenticate users. The system records a series of vocal features such as pitch, volume, and accentuation which are used to create a “voiceprint” that serves as an individual's digital signature. Artificial intelligence (AI) and machine learning algorithms are used to match these voiceprints with the ones stored in the biometric database for authentication purposes.

Voice recognition is increasingly being used in call centers, allowing businesses to quickly and accurately verify the identity of their customers. Voice biometrics can also be used in customer service automation, access control, and secure payment systems, to name a few applications.


Gait is how an individual walks, and it can be used to create a unique biometric identifier. This technology relies on analyzing different factors such as walking speed, stride length, and body posture to authenticate a person's identity.

Gait recognition systems use cameras and other motion sensors to track an individual's walk and create a “gait map” that acts as their biometric signature. Gait recognition is still a relatively nascent technology and has yet to be widely adopted, but it is being tested in a variety of biometric security applications such as surveillance and access control systems.

Keystroke Dynamics

Keystroke dynamics is an effective security measure that utilizes a user's unique typing pattern to identify any attempts of malicious access or suspicious online activities.

This strategy entails examining the speed and rhythm in which someone types on their keyboard, allowing it to work alongside passwords and PINs for effective two-factor authentication. It provides an additional layer of protection to online applications, ensuring they remain safeguarded from unauthorized users.

Mouse Movements

Mouse dynamics is a type of behavioral biometric that involves analyzing the speed and pattern of someone's cursor movement on a computer screen. This technology works by tracking a user's mouse movements and then generating a “mouse map” which acts as their unique digital signature. Mouse dynamics are mainly used for user authentication and access control, as well as fraud detection in online banking.


As its name implies, signature biometrics makes use of a person's unique handwriting to authenticate them. This signature recognition system requires users to sign their names on a digital tablet or a piece of paper and have their signatures stored in the database. Each time they need to access a particular system, they will be required to sign again and the system will match it with their stored signature to grant access.

Signature biometrics are often used in secure payment systems, allowing customers to make payments without having to provide their credit card information or PINs. It is also used in document management systems which require the signature of its users to approve transactions.

Biometrics technology brings unparalleled security and convenience to users while simultaneously safeguarding their sensitive data. With its multifaceted physiological, as well as behavioral traits, biometrics can be applied in a wide range of applications such as payment transactions, border control, biometric security systems, civil identification, benefits management, and much more. As the digital age continues to unfold, we will see a further increase in both the accuracy and adoption of biometric technologies.

Biometric System Components

At its core, a biometric system collects and stores biometric information from the physical or behavioral characteristics of a person, typically via a sensor. It then verifies or identifies an individual by comparing this data with a reference template. It is important to note that biometric systems used in a variety of applications must adhere to three key components, which include:

1. Biometric Hardware:

Hardware components such as sensors, cameras, canners, and other devices are used to capture biometric data. Fingerprint scanners, iris scanners, and facial recognition terminals are all examples of biometric hardware.

2. Software:

Software components bridge biometric devices and the computers they are linked to, allowing for interoperability between them. They also enable biometric systems for processing, storing, and sharing biometric data, as well as matching it with existing reference templates during authentication or identification tasks. Facial recognition algorithms, Device Management System (DMS), and Automated Biometric Identification System (ABIS) are examples of software used in biometric systems.

3. Biometric Databases:

This is the repository for biometric data, typically consisting of a collection of biometric templates and other personal details from enrolled individuals. These databases are typically used as a reference library for biometric comparison during identification or authentication tasks. Aadhaar in India, the FBI's Next Generation Identification (NGI) system in the United States, the elections system in Nigeria, and the European Dactyloscopy (Eurodac) system in the European Union are all well-known examples of biometric databases.

Biometric System Working Steps:

To understand the full scope of a biometric system, it's useful to consider its working steps. From enrolling individuals to verifying their identities, biometric systems are designed to work in a number of stages:
