Interpretation of Biometric Access Control Systems

Biometric Access Control System is an expert fingerprint access and time attendance control system. It is widely used in confidential places for its easy installation and high security. To secure your life tommorrow, it's the best choice for you today. Biometrics is the technical term for body computation and estimation. It refers to metrics related to human characteristics. In Biometric Access Control system, biometric authentication refers to the recognition of human beings by their physical uniqueness. Biometrics authentication is used in computer science as a form of identification and access control. It is also helpful to identify individuals in groups that are under surveillance.

Biometric identifiers are categorized as physiological and behavioral characteristics. Physiological characteristics are related to the shape of the body. While behavioral characteristics are related to the pattern of behavior of an individual. This system works on substantiation. Biometric Access Control system scans the person and matches his/her biometric data with the previously stored information in the database before he/she can access the secured zone. If the compared information matches, the system allows the person to access the zone. Nowadays, Biometric Access Control system is considered to be the best and one of the most secure authentication systems amongst the other access control system.

Biometric Access Control Principles.

In principle, a biometric system is a pattern recognition unit that assembles a specific type of biometric data from a person, focuses on a relevant feature of that data, analyzes that feature to a group of attributes in its database, and then performs an action based on the accuracy of the comparison. A standard biometric access control system consists of four main types of components: a sensor device, a quality assessment unit, a feature comparison and matching unit, and a database.

Sensor Unit

It forms the key interface between a user and a biometric access control system. The data obtained through the sensor mainly depends on the camera characteristics because the biometric data is mainly composed of images, with exception of voice recognition and odor identification.

Nature of Data Estimation

The data obtained from the sensor device must be evaluated before processing it. In order to improve the quality of the data obtained an algorithm designed for signal strengthening is applied. But if the quality of data is low, then the user may be asked to resubmit the data. After processing, a set of features is selected from overall data to show the qualifying identity trait. The feature set which used for estimation and extraction is known as the biometric template and is stored in system’s database.

Correlation and matching of data.

After extraction of gathered data, it is compared with the stored templates and matched with any identical points. A match score is provided if a matching point is obtained between the input and template, it may fluctuate depending on the quality of collected data. The matching device includes a decision-making apparatus which relies on the match score.

System Database

For processing the biometric readings database stores all information. In order to enhance security levels while establishing access control parameters, the feature template is input into the database. The processes like parameter setting and data gathering may be under the supervision of technician or automated. For extraction of the template a single biometric sample is needed, but in some cases, a biometric system process multiple samples. This is often found in facial recognition biometrics.

Categories of Biometric Access Control System

It is classified into two types such as Physiological Biometrics and Behavioral Biometrics. The physiological biometrics includes face recognition, fingerprint, hand geometry, iris recognition and DNA. Whereas behavioral biometrics include keystroke, signature and voice recognition.

  • Finger Print Recognition

    It includes taking a fingerprint image of a person and records its features like arches, whorls, and loops along with the outlines of edges, minutiae, and furrows. Matching of the fingerprint can be obtained in three ways, such as minutiae, correlation, and ridge. To capture the fingerprints, present methods employ optical sensors that include a CMOS image sensor or CCD, solid-state sensors. Scanning of the sensor is very stable and reliable. It helps to safeguards entry devices for the building.

  • Face Recognition

    It is a type of biometric computer application which can identify or verify a person from a digital image by comparing and analyzing patterns. It is used in security systems. This system works with face prints and can recognize 80 nodal points on a human face. It works by capturing data for the nodal points on a digital image of a person’s face and resulting data can be stored as a face print. Social sites like FB uses software for face recognition to tag the users in photographs. This software also increases marketing personalization.

  • Iris Recognition

    It is a type of biometric method used to identify the people based on single patterns in the region of ring-shaped surrounded the pupil of the eye. Generally, the iris has a blue, brown, gray or green color with difficult patterns which are noticeable upon close inspection.

  • Voice Recognition

    This technology produces speech patterns by combining behavioral and physiological factors that can be captured by processing the speech technology. The most important properties used for speech authentication are nasal tone, fundamental frequency, inflection, cadence.

  • Signature Recognition

    It is a type of biometric method used to analyze and measure the physical activity of signing like the pressure applied, stroke order and the speed. Signature recognition can be operated in two different ways, such as static and dynamic.

  • Finger Vein Reader

    The Finger vein reader captures an image of the vein patterns which exist beneath the surface of the finger. Vascular pattern is detected using a near-infrared LED. It detects the hemoglobin in the bloodstream, providing a distinct pattern.

  • Multi-biometric Readers

    Multimodal readers read a number of different biometrics. For example, they can read both fingerprint and/or finger vein, or fingerprint plus facial recognition. It uses a combination of facial features and the way a person walks towards the camera. These systems operate very quickly and improve the accuracy.
