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 

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

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

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

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.
