Types of Biometric Devices

Biometric equipment is utilized for security identification and authentication. These tools can identify a user and then successfully demonstrate whether the identified user is who they say they are. 

Biometric security systems use automated procedures to minimize human participation to identify and verify a person’s identity based on distinguishing physiological or behavioral attributes.

Unique biological characteristics, such as facial geometry, fingerprints, and iris patterns, are impossible to duplicate and remain in the user’s memory forever. Types of Biometric Devices comes in a variety of forms.

Biometric Device Fingerprint Scanner

Types of Biometric Devices

The most established and ancient biometric recognition technique is fingerprint analysis. Since its inception, forensic investigation has included fingerprint identification. As forensic investigation organizations used technology to refine the fingerprint identification and matching process, it kept getting better. Today, it is utilized on smartphones, door locks, and high-security access control.

A person’s identity data becomes their biometric fingerprint identity linked to this template. This biometric template can be compared to recent or old scans, and the biometric system will either find a match or not, depending on the circumstances.

At the user level, a fingerprint recognition system is just a “touch and go” process, in which gaining access is as simple as touching the sensor.

Biometric Palm Scanner

The extended form of fingerprint recognition is known as palm print recognition. The technology used to scan and process palm prints is substantially the same as that used for fingerprint recognition. Palm prints contain additional details such as the shape of the hand, datum points, wrinkle features, delta point features, and minutiae features (similar to those in fingerprints).

In forensic and criminal investigations, palm prints have been used to identify people at crime scenes; their reliability in these contexts has paved the way for commercial biometric applications. Automated palm print recognition systems use digital cameras or scanners to take pictures of the palm. 

Facial Recognition System

Humans mostly use a person’s facial structure to identify them. It can also be used for human identification and authentication and is a well-known biometric modality. As a result of the capacity to zoom in several times on modern, high-quality cameras, it is now possible to recognize a subject from a distance, making face recognition helpful for security and surveillance applications.

One of the fast-expanding biometric modalities is facial recognition. The factors contributing to this expansion are the rise of smartphones and personal computers. Face recognition for user identification is a simple process thanks to modern smartphones requiring two cameras, one on the front and one on the back. Infrared emitters and cameras that take IR illuminated 3D maps of facial anatomy are now being added by device manufacturers as additional hardware for face identification.

Iris Scanner

One of the first-generation biometric technologies, iris recognition, has become the de facto standard for identification and authentication in many use scenarios. The colored area resembling a human eye ring is called the iris. It is composed of numerous thick, asymmetric thread-like formations if you look closely. These thread-like structures represent the muscles that help alter the pupil’s shape and only permit the proper quantity of light into the eye.

The muscle folds in the iris to form a pattern particular to each individual and can be used to recognize or confirm that person. Combining an iris scanner, a digital, infrared, or both cameras, and processing software allow iris-based recognition. The program might also have a liveness detection tool that requires patients to blink for their eyes to be scanned.

The software pre-processes the image to make it more useful, and then a recognition algorithm processes it to extract distinctive features. Eventually, a biometric template is created that may be used to enroll users or run matches against already registered data.

Voice Recognition Devices

Physiological and behavioral biometrics are combined in voice or speech recognition. It employs speech patterns that speech recognition software has recorded. This system examines speakers’ fundamental frequency, nasal tone, tempo, inflection, and other factors to identify their speech.

The technology is also known as “computer speech recognition,” “speech to text,” and “automatic speech recognition.”

Biometrics was once considered an essential technology for the military and government agencies. But as technology advanced, biometrics became a common security procedure in our daily lives. Additionally, technology improves affordability and dependability. At BioSyn, we aim to understand each client’s particular needs.
