Let’s Get Started!!
What are Types of Biometric Authentication?
There are different types of biometrics; but they are mainly classified under two categories like as physiological biometrics and behavioral biometrics. Below mentioned both in detail with their types, as following them:
Physiological biometrics enables with the unique and measurable physical characteristics of an individual that are used for identification and authentication objectives. By analyzing and comparing these distinctive biological features, it ensures accurate and efficient verification, offering a higher level of privacy and protection against fraud or unauthorized access.
Types of Biometrics in Physiological:
Here, we will show you different types of biometrics that fall under Physiological Biometrics methods; below shown each one:
Fingerprint authentication method aids to identify the individuals based on the unique patterns on their fingertips. It enables to capturing and analyzing the ridge patterns, loops, and whorls of a person’s fingerprint that are creating a different digital representation.
Fingerprint recognition is mostly utilised in several areas like as unlocking smartphones, securing access to buildings and devices, and in law enforcement for criminal identification.
Iris recognition helps to identify the individuals by analysing the unique patterns in their irises, including the colored part of the eye surrounding the pupil.
Iris recognition provides the higher of accuracy and security due to the stability and complexity of iris patterns, and it is also making with suitable for applications like as, access control, border control, and national identity systems.
Facial recognition is a special biometric technology that aids to identify and verifies individuals by analysing their unique facial characteristics. It enables with computer algorithms to capture, process, and make the digital representation of a person’s face, called as a facial template.
This template is compared apposite to the database of stored templates to find a match, enabling identity verification or access control. Facial recognition is mostly used in various segments like as smartphone unlocking, surveillance systems, airport security, and law enforcement.
Voice recognition is also known as speech recognition; and this technology helps to convert spoken language into text or commands. It uses the advanced algorithms and machine learning to analyse the acoustic features of a person’s voice, like as pitch, tone, and pronunciation, to make a unique voiceprint.
This voiceprint is then compared to pre-existing patterns that is stored in a database for authentication or command execution. Voice recognition is mostly utilised in voice assistants, voice-controlled devices, and call center applications.
DNA matching is a process aids to compare and analyze the unique genetic material, DNA, of two or more individuals. It enables the examining certain regions of the DNA sequence to make identification similarities and differences.
DNA matching is mostly employed in forensic investigations to attach suspects to crime scenes and identify missing persons. By helping of paternity testing, it helps determine biological relationships in between individuals.
Ear authentication biometric refers to identify individuals based on the unique features and shape of their ears. It enables with capturing images and 3D scans of an individual’s ears and extracting different characteristics including the ear canal, lobule, and ridge patterns.
These features are helped to make an ear template that is compared to stored templates in a database for making to verification and identification. Ear authentication serves the contactless and discreet method for personal recognition, with including some applications in access control, surveillance, and medical.
Finger Vein Recognition
Finger vein recognition technology refers to identify the individuals by analysing the unique patterns of veins in their fingers. It executes by capturing near-infrared images of the finger that highlight the vein patterns underneath the skin’s surface.
Now, these patterns are converted into digital templates and compared to save templates in a database for authentication or identification. Finger vein recognition serves the secure and reliable method of biometric authentication. It is mostly used in access control systems, financial transactions, and healthcare applications.
Teeth biometrics authentication aids to identify the individuals depend on the different arrangement and features of their teeth. It refers to capturing higher-resolution images or scans of the teeth that are considering factors including the tooth size, shape, and alignment.
These features are implemented to make the dental template, which is then compared to save templates in a database for authentication or identification.
Electroencephalogram biometrics technology that identifies individuals based on their brainwave patterns; it enables the recording and analyzing the electrical activity of the human brain via EEG sensors that is placed on the scalp.
The brainwave patterns are processed to make the distinctive brainwave template, named the “brainprint.” So, it is offering the novel and highly secure concept of biometric identification, and brainwave patterns are most difficult to mimic or forge.
It can find applications in various domains like as access control, authentication for locked-in patients, and brain-computer interfaces.
Electrocardiogram (ECG) biometrics technology aids to identify individuals based on their heart’s electrical activity. It includes the recording and analyzing the electrical signals that are generated by the heart through ECG sensors that are also placed on the body.
The distinctive ECG patterns, such as P-waves, QRS complexes, and T-waves, are extracted and used to make a unique “heartprint” or ECG template. ECG biometrics serves the secure and reliable method of biometric identification, and the heart’s electrical patterns are specific to each individual.
Nailbed recognition method aids to identify the individuals based on the unique patterns and features that are available in their nailbeds. It enables to capturing higher-resolution images or scans of the nailbeds, then analyzing attributes like as the texture, shape, and ridges.
These features are going to use for making the digital template (nailprint); and this nailprint is compared with saved templates into a database for authentication or identification purposes. Nailbed recognition provides the non-intrusive and contactless biometric identification, suitable for situations where other biometric modalities like fingerprints may not be available or suitable.
