Information security is essential in today’s digital world. One of the most important controls for ensuring information security is authentication, which is the process of verifying someone’s identity.

Authentication is used in many different contexts, such as logging into a website, making a purchase with a credit card, or withdrawing cash from an ATM. It is also used in physical security settings, such as when entering a secure building.

Without authentication, anyone could claim to be someone else and gain access to sensitive information or resources. This could lead to identity theft, fraud, and other security breaches. Authentication is essential for protecting people and their information from those with malicious intent. It is the bedrock of information security. 

Here are some examples of the importance of authentication:

• If you want to make a purchase on a shopping site, you need to prove that you own the card being used to make the purchase.
• If you want to withdraw cash from an ATM, you need to enter the correct PIN.

Authentication can be performed in a variety of ways, including using passwords, PINs, tokens, passcodes, fingerprints, facial recognition, and other biometric methods. The best authentication method for a particular situation will depend on factors such as the level of security required and the convenience of use.

Which type of authentication method is best?

In general, authentication comes in three forms

“What you know” authentication is the most common type of authentication, but it is also the least secure. However, by using strong complex passwords, changing passwords frequently, and using two-factor authentication can make this method more secure.

Examples include Passwords, codes, secret words, and pins. That being said Passwords and PINs can be easily forgotten, lost, or stolen. It may be sufficient for a low-risk application, such as a personal website. 

“What you have” authentication is more secure than what you know authentication, but it can be inconvenient if the user loses their token or key device. Examples here include: Identity cards, one-time password token devices, smartphone authenticators, passwordless methods

“Who you are” authentication is more secure than others mentioned, but it can be more expensive to implement and may not be suitable for all applications.  it is also important to note that no authentication is not foolproof especially when used in isolation.

However, who you are authentication may be required for a high-risk application,  including financial systems, healthcare, education, government services, and law enforcement. It is also becoming increasingly popular in consumer applications, such as smartphones and laptops. Examples of who you are authentication include facial biometrics, fingerprint, iris, retina, voice, and other behavioral patterns unique to a person.

The best type of authentication for a particular application will depend on the level of security required and equally important, how convenient it is to execute the method. 

Biometric authentication has a number of advantages over other types of authentication:

• It is very difficult to forge or replicate biometric data.
• Biometric authentication is convenient and easy to use.
• Biometric authentication is non-transferable, meaning that it cannot be shared with or stolen by others.

Who you are authentication, also known as biometric authentication, is the most secure type of authentication. It uses your unique biometric characteristics, such as your fingerprint, finger vein, facial features, iris, retina, or voice, to verify a person’s identity.

As biometric authentication technology continues to develop and become more affordable, it is likely to become the dominant authentication method in the future.

Let’s go over the main types of Biometric verifications.

Types of Biometric Verification

Facial recognition technology uses facial features to identify someone. It works by comparing a live image of someone’s face to a database of known faces. Facial recognition technology is becoming increasingly popular in a variety of applications, including law enforcement, security, and consumer electronics.

Fingerprint scanning is a type of biometric authentication that uses fingerprints to identify someone. It works by scanning the ridges and valleys on a person’s fingerprint and comparing them to a database of known fingerprints. Fingerprint scanning is one of the most widely used biometric authentication methods, and it is used in a variety of applications, including law enforcement, security, and access control.

Retina scanning is a type of biometric authentication that uses the unique patterns of blood vessels in the retina of the eye to identify someone. It works by scanning the retina and comparing it to a database of known retinas. Retina scanning is a highly secure biometric authentication method, but it is also more expensive than other methods.

Iris scanning is a type of biometric authentication that uses the unique patterns in the iris of the eye to identify someone. It works by scanning the iris and comparing it to a database of known irises. Iris scanning is a highly secure biometric authentication method, and it is also more expensive than other methods.

Finger vein scanning is a type of biometric authentication that uses the unique patterns of veins in the finger to identify someone. It works by scanning the veins in the finger and comparing them to a database of known finger veins. Finger vein scanning is a highly secure biometric authentication method, and it is also more expensive than other methods.

Voice scanning is a type of biometric authentication that uses a person’s voice to verify their identity. It works by analyzing the unique patterns of a person’s voice and comparing them to a database of known voices. Voice scanning is a less secure biometric authentication method than other methods, but it is also more convenient.

Biometric authentication is a powerful tool that can be used to improve security in a variety of settings. However, it is important to choose the right biometric authentication method for the specific application. Factors to consider include the level of security required, the cost of implementation, and the convenience of use.

The most popular forms of biometric authentication amongst those mentioned are the facial recognition type and fingerprint scan type. Facial biometric authentication in particular is an essential part of modern security measures, and it is becoming increasingly popular as technology advances.

A deeper look at facial biometrics

Facial Biometric authentication is already being used in a wide range of high-risk applications, including financial systems, government services, and law enforcement. It is also becoming increasingly popular in consumer applications, such as smartphones and laptops.

Here are some specific examples of how biometric authentication is being used today:

• Banks are using facial recognition scanners to verify the identity of customers who are making withdrawals or accessing their accounts online.
• Governments are using facial biometric authentication to issue passports and visas and to verify the identity of travelers at border crossings.
• Law enforcement agencies are using biometric authentication to identify and track criminals.
• Smartphone manufacturers are using fingerprint and facial recognition scanners to unlock devices and authenticate payments.
• Laptop manufacturers are using fingerprint scanners to unlock devices and authenticate users.

Facial biometrics has grown in popularity in recent years, but it is important to be aware of both its pros and cons before using it.

Pros:

• Improved security: Facial biometrics (recognition) technology can be used to identify and deter criminals, and to prevent unauthorized access to secure areas.
• Improved customer experience: Facial recognition technology can be used to speed up authentication processes and improve the overall customer experience.
• More accessible: Facial recognition can be used by people with disabilities and other conditions that may prevent them from using fingerprint scanners.
• Accurate: Facial recognition technology has become increasingly accurate in recent years.

Cons:

• Threat to privacy: Facial recognition technology can be used to track people without their knowledge or consent, which poses a threat to privacy.
• Highly sensitive database vulnerabilities: If a database of facial scans is breached, attackers could gain access to a large amount of sensitive personal information.
• Recognition accuracy: Facial recognition technology is not always accurate, especially when used to identify people who are moving or who are in poor lighting conditions. Also in situations where a person has a look-alike, like a twin, it may be a challenge to authenticate the person.

How to mitigate the risks of facial recognition technology:

• Use strong encryption to protect facial scan databases.
• Implement strict access control policies for facial scan databases.
• Use facial recognition technology in a responsible and ethical manner.
• Using facial biometrics in the context of multi-factor authentication i.e. together with other authentication methods.

The future of biometric authentication technology

As biometric authentication technology continues to develop and become more affordable, it is likely to revolutionize the future of authentication. Biometric authentication offers a number of advantages over traditional authentication methods, such as passwords and PINs, including improved security, convenience, and accessibility.

For example, biometric authentication can be used to create more secure authentication systems that are less susceptible to hacking and other forms of cybercrime. Biometric authentication can also be used to create more convenient authentication systems that do not require users to remember or carry passwords or other authentication factors. Additionally, biometric authentication can be used to create more accessible authentication systems that can be used by people with disabilities and other conditions that may prevent them from using traditional authentication methods.

Ultimately, the best authentication method for you will depend on your specific needs and preferences. It is also important to consider the potential risks of each authentication method. 

Among the top two biometric authentication methods, Facial recognition is more accessible to the general public when compared to using fingerprints as a biometric authentication method. However, in terms of precision, Fingerprint biometrics provides more accurate verification of a person’s identity. There just happens to be more support for facial biometrics based on the availability of supporting technology on a widespread level.
