Previously, mostly government organisations, public and private businesses used a paper process to recognise staff, vendors, visitors etc. This paper system was used for sign-in/sign-out system. The paper method is now outdated and now replaced with biometric authentication. The development of various forms of biometric technologies within organisations, without dramatically raising expenditure, contributes to a highly accountable safety and attendance maintenance system. Via its high degree of specificity and reliability in combating identity fraud, individuals and visitors attendance records obtained various forms of biometric technology with open arms. Not only in organizations, but different types of biometric systems are also widely used in examination centers as well.
Different forms of biometric technologies not only fulfill the expectation but also surpass that, as IDs and passports may be forged. The biometric attendance system is advanced, insightful, super-sensitive, and built to help protect businesses and individuals. Especially as the name implies that biometrics operate on biological features of an individual, it is impossible to steal or replicate it. One is biologically distinguished by two types: behavioural and physical.
Biometrics of Comportement:
Verifying an individual is made possible through behavioural biometrics. The keystroke identification and speaking identifier can be split into two forms.
Recognition of Keystrokes:
It is immensely beneficial to eliminate illegal operations such as insufficient e-mail and dishonest printing. Due to the fact that the name of the keystroke recognizes tests the typing pattern of the user. Computers that use keystroke recognition tools will recognise incorrect behaviours and deliver the message to the right people to take corrective action.
These kinds of biometric technologies evaluate the voice pattern, speaking style, and pitch of a person. Unknown speaker identity is helpful so as to reduce threats via telephone calls, web calls, etc.
The physical biometric is used in recognizing and identifying persons. The physical attributes of a person are so different from another that it is difficult to commit offences like identity theft. There are various forms of biometric environmental technologies and they are listed shortly below:
Identification of Fingerprints:
Fingerprint recognition is one of the oldest forms of identification methods. Their use is widely noticeable. Fingerprint authentication is the easiest and most effective way from entering workplaces to accessing mobile devices. Different people’s fingerprints are not identical. There are estimates that one in one billion prints can be matched. It detects and verifies a person’s fingerprint, like all other biometrics technology, with previously saved data. The technology has been adopted by law enforcement authorities, hospitals and clinics, schools and universities, wellness centres to identify people and screen them properly.
Identification of a Finger Vein
The underlying surface of a finger is used for this method of recognition. It is noticed that the vein pattern of any person is unique and cannot be matched. Identification of the finger vein is a highly protected technique since it is not destroyed or changed under the finger surfaces.
Authentication of Palm Vein:
Because of their high-sensitivity, security and super-sensitivité, the Japanese Ogaki Kyoritsu Bank introduced palm vein innovations in 2016. It is identical to the examination of the fingerprint. A camera captures and examines palm prints and other facial characteristics to recognise an individual’s palm.
Iris Recognition System
Iris recognition is one of the most popular biometric technology. This trending security is mostly used in banks and other financial institutions due to its fast speed and minimal margin of error. Iris is an organ in the eyes that remains stable structure throughout life. Based on high resolution and distortion-free images, an iris recognition device uses pattern recognition techniques. This technique stores the data for future errorless identification and verification.
Facial Recognition System
A biometric face recognition system uses face recognition technologies to identify, validate and automatically indicate an individual using his face features.
The app will be used by various classes such as workers, students and so on. In real-time, the machine tracks and stores the data. One contactless way to handle visitors and staff in the company is through a facial recognition system.
A facial recognition device is a touchless way to manage staff and visitors, compared to other types of biometric systems, such as fingerprint that collects identities by touch. A touchless device is an effective preventive measure in times of the COVID-19 pandemic. It facilitates the secure and effective handling of human inflows and outflows in buildings and premises.
