In this blog, we delve into the benefits of biometric authentication techniques, equipping you with the knowledge needed to make informed decisions regarding your identity management strategy.

Anonybit’s identity management platform offers a comprehensive solution to help you effectively implement biometric authentication techniques and streamline your security processes. It ensures you are well-equipped on biometrics and its advantages and disadvantages.

What Are Biometrics?

backend system of biometric - Advantages Of Biometrics

Biometrics are authentication processes that leverage an individual’s physiological and behavioral characteristics to identify their identity accurately. In a world dominated by passwords and PINs, biometrics offer a refreshing alternative. Unlike traditional authentication methods that rely on something you know (passwords) or something you have (security tokens), biometrics leverage what you are—an individual with distinctive physiological or behavioral traits.

Like metrics, biometrics involves comparing data sets to find patterns and trends. They do the same by comparing a biological data set of “something a person has” with “something they are” – a phrase often used by identity experts discussing the “lock and key” and token approach to user identification and authentication in modern password systems.

Types of Biometrics

Biometrics can be grouped into two main categories: physiological biometrics and behavioral biometrics. Physiological biometrics are characteristics or measurements of the human body, whereas behavioral biometrics refer to the unique way a person performs a certain behavior, like giving a signature. The categories can be further broken down as follows.

Some of the different kinds of behavioral biometrics include:

  • Keystroke recognition
  • Gait recognition

Keystroke Recognition

Think of this element as the digital world’s version of handwriting analysis. It’s not to be confused with keylogging, noting what a person is typing. Keystroke recognition is a method of recording a person’s individual typing pattern, including the pace at which a person types particular letters or words, to isolate and identify the person doing the typing.

Gait Recognition

Although a system that tracks a person’s steps may not be feasible in every situation, it can be an accurate identifier of an individual.

Physiological Biometrics

Physiological biometrics are much more common because many unique physiological factors are relatively easy to track. This biometric category analyzes physical measurements of the human body, such as the face, fingerprints, hand geometry,  iris, and more. Physiological biometrics can include:


It’s well-known that every person has unique fingerprints. Fingerprints have been used to identify people since long before the digital age, so it’s a logical choice for biometrics. Fingerprint identification is cheap, affordable, and typically extremely accurate.

Vein Recognition

Vein patterns, as they happen, are also unique to individuals. Technology currently exists to examine finger or palm vein patterns. Vein identification is more secure than fingerprint identification because while it’s conceivable that fingerprints could be altered, it’s difficult to imagine how a vein pattern, being subdermal, could be altered in a useful way.

Iris Recognition

Another popular method of biometric identification is eye pattern recognition. The user simply looks into an eye reader, which may analyze the iris pattern to match it to an approved user profile.

Facial Recognition

The most popular biometric modality, facial recognition, is a smartphone staple in airports and other large-scale environments. The technology is very user-friendly and allows for manual backups, which most other modalities do not provide. 

DNA Matching

While collecting DNA from a user every time they want to gain access to a system may be considered a bit too invasive, there’s no denying the high effectiveness of DNA analysis in identifying individuals.

Voice Recognition

This method of authentication analyzes the sounds a person makes when they speak.

Digital Signatures

These analyses include static systems that simply compare the signature to an existing handwriting sample and dynamic systems that also track the movement of the person’s hand when writing.

How Are Biometrics Used?

Biometrics are commonly used to authenticate a person’s identity. Examples include using fingerprint or facial recognition to access smartphones or facial recognition technology at airport smart gates. Using biometrics to authenticate individuals is also known as one-to-one matching.

Biometric Systems

In one-to-one (1:1) biometric systems, a person’s biometric characteristic(s) are compared to the system’s existing data for that individual. In this instance, the individual has previously provided their biometric information for future authentication purposes.

Active vs. Passive Authentication

Most biometric systems used for authentication require the individual to actively provide their biometric characteristic, which matches existing biometric information in a database. Authentication can also occur passively, where the individual does not have to participate actively in the process.

The Rise of Passive Authentication

Instead, their biometric characteristic is collected and authenticated in the background as the individual transacts with the organization or service. For example, a person’s voice biometric may be collected and authenticated as they talk to a customer service representative over the phone.

Measuring Habits and Patterns for Security

Behavioral biometrics are increasingly used for passive authentication, often as an additional layer of fraud prevention. As noted above, this involves measuring and tracking patterns in how an individual moves, behaves, or uses something physically. This can range from how a person holds and moves a device, such as a mobile phone, to how their fingers tap the screen and the force of their taps. A person’s language (for example, their choice of words, grammar, sentence structure) can be measured as a biometric characteristic.
