Different types of Biometric System

Biometrics is a method of establishing a person’s identity based on chemical, behavioral, or physical attributes of that person, and is relevant in large-scale identity management across a wide range of applications. In principle, a biometric access control system is a pattern recognition unit that gathers a specific type of biometric data from a person, focuses on a relevant feature of that data, compares that feature to a preset group of attributes in its database, and then performs an action based on the accuracy of the comparison. Access control refers to the management of an access point, such as a door, turnstile, elevator, etc. so as to only allow entry to authorized users. there are two types of biometrics: Behavioral Biometrics and Physiological Biometrics.

Behavioral Biometrics

Behavioral Biometrics is the scientific study of how people’s and animals’ bodies function.

It is further divided into;

  • Signature Recognition

Signature recognition is one type of biometric method used to analyze the physical activity of signing by measuring special coordinates such as pen pressure, stroke order, inclination, and speed. A measurements are digitally recorded, then that information is used to automatically create a biometric profile for future authentication.

  • Keystroke Dynamics

Keystroke dynamics leverage the fact that people follow a definite pattern while typing on a keyboard or keypad.Their keystroke rhythm can be used to establish a biometric profile, which can be used to identify or authenticate him/her. Time taken to press each key, pause between key presses, letters typed per second/minute, and several other measures are taken to generate a keystroke profile of a user.

  • Voice Recognition

Physically speaking, the shape of a person’s vocal tract, including the nose, mouth, and larynx determines the sound produced. Behaviorally, the way a person says something – movement variations, tone, pace, accent, and so on – is also unique to each individual. The most important properties used for speech authentication are nasal tone, fundamental frequency, inflection, cadence. Combining data from both physical and behavioral biometrics creates a precise voiceprint.

Physiological Biometrics

Physiological biometrics is based on a behavioral trait of an individual. It involves all physical characteristics like, ears, eyes, iris, fingerprints, etc.

Here are some subdivisions of physiological biometrics;

  • Fingerprint

Fingerprints are easy to capture, and can verified by comparing the unique loops, arches, and whorls in each pattern. After capturing the print, sophisticated algorithms use the image to produce a unique digital biometric template. The template is then compared to new or existing scans to either confirm or deny a match.

  • Facial Recognition

Facial recognition software measures the geometry of the face, including the distance between the eyes, the distance from the chin to the forehead, and multiple other points on a person’s face. After collecting the data, an advanced algorithm transforms it into an encrypted facial signature.

  • Retina Scan

Retinal scans capture capillaries deep within the eye by using unique near-infrared cameras. The raw image is first preprocessed to enhance the image then processed again as a biometric template to use during both enrollment and verification.

  • Iris Scanner

Iris scanners use infrared light and high-resolution cameras to create a detailed map of the iris, then convert this information into a template that becomes a person’s biometric ID.

  • Palm Vein

Palm vein is a relatively new biometric that works by using infrared light to map the unique vein pattern of the palm.
