Biometric Security: Guide to Visitor Management System Biometrics


  • Physiological Biometrics
  • Behavioural Biometrics

Biometric security authorizes access by evaluating the unique functionality and characteristics of an individual. Identifying these parameters secures and authenticates access to an establishment, website or application. This method is an important layer of security for every organization. Biometric software devices can validate the following: fingerprints, voices, an eye scan or a pulse recording.

In this digital age, biometric security is one of the most advanced security systems. Moreover, it provides an exclusive, different, and unique identity for each person before giving access. It can set up dedicated fingerprints and secure locks for every individual. In addition, it has a private system of security at the level of advancement.

Advantages of Biometric Security

Biometric Security offered a safe and advanced way of the authentication procedure. This is highly considered by different organizations due to the key benefits gained. The following are some of the strong characteristics of utilizing biometric security.

Biometric Security Increases Security

Nowadays, traditional data security through passwords is not enough. The digital world has become advanced and different security measures have been developed. One of the most popular security methods for access today is two-factor authentication. However, choosing biometrics authentication has been considered a better option. In two-factor authentication, keeping two parameters for access takes too much load for individuals. Biometric authentication is preferred for its simple method and unique access given per individual.

Efficient Security Evaluation

Using biometrics is a special way to recognize all individual identities. It means entries can never be repeated and duplicated for all individual identities. There are various types of biometric authentications. For instance, the eye scanning of each person can generate unique data for every individual. Other examples are fingerprint scanning. Fingerprint scanning secures data more effectively than any other way.

Types of Biometric Security

Physiological Biometrics


Fingerprint scanning is one of the most recognized biometric security. After capturing the fingerprint, algorithms will be used to produce a unique digital biometric template. The generated template will be compared to new or existing scans. This will determine if the template is a confirmed or denied match before granting access.

Finger or Hand Veins

Finger or hand veins scanning is considered harder to hack than any other biometric scan. To elaborate, infrared lights pass through the skin surface where they absorb into deoxygenated blood. A special camera will be used to capture the image. The image will digitize the data and then either store it or uses it to confirm identity.

Iris Recognition

Thread-like muscles can be found on a person’s iris. It is the coloured part of the eye. The muscles on the iris help shape the pupil. Because of this, the amount of light that enters the eye is controlled. In biometric security, measuring the unique folds of these muscles can confirm an individual’s identity. To add an additional layer of security, liveness detection can also be added. Liveness detection pertains to requiring an individual to blink for a scan.

Retinal Scan

Utilising a retinal scan in biometric security means capturing capillaries deep within the eye. Unique near-infrared cameras are used in retinal scans. The image will be enhanced first as it is pre-processed. Then, the image will be processed once again as a biometric template. The processed image will be used during enrollment and verification.

Facial Recognition

The oldest form of biometric authentication is the facial recognition method. Biometric facial recognition software works as much as how infants recognize facial features to determine the people closest to them. However, biometric facial recognition software has a more precise measurement for biometric security.

A facial recognition software measures an individual’s face geometry such as the distance between the eyes, the distance from the chin to the forehead, and more. Once the data is collected and processed, an advanced algorithm transforms this into an encrypted, unique, facial signature.

Voice Recognition

Voice recognition can be classified under physiological and behavioural biometrics. In a physical sense, the shape of a person’s vocal tract can determine the sounds produced. For instance, the shape of the nose, mouth, and larynx. In the behavioural biometric sense, how a person says something is unique to each individual. This pertains to the movement variations, pace, accent, tone, and more. When these characteristics are combined, it creates a unique and precise vocal signature. However, the voice signature is prone to mismatch if the person is sick. Many other factors can also affect and change an individuals’ voice.

Behavioural Biometrics

Behavioural biometrics are measured behaviour patterns. They are opposite or in addition to physiological characteristics. Some examples of behavioural biometrics are gait biometrics, lip movement, signature recognition, and keystroke.

Biometric technology helps obtain the unique characteristics of an individual to confirm identity. This unique signature, whether physiological or behavioural, can help improve security compared to other traditional security measures. Qbasis’ visitor management system can enhance an establishment’s security and protect the organization’s data by integrating biometric security software and scanners into the system.
