The process of identifying and recognizing human beings based on their physical and behavioral traits is called biometrics. Fingerprints, face recognition, iris recognition, DNA matching are some of the popular biometric parameters. Even one’s gait, voice, and typing rhythm also serve as parameters for biometrics. When people’s access to secure areas is obtained by matching their physical characteristics through a computerized method it is known as biometric access control.
Biometric security nowadays has become the most accurate and reliable method of security as it is based on the physical attributes of a person which are bound to be unaltered. Unlike PIN numbers or cards, there is no chance of biometrics to be stolen or lost or to be left back at home. It is completely unique to a person and can never be used by another person. Thus it authenticates people and stores in its database for further matching whenever the person requires entry into that secure area.
Biometric access control is gaining popularity by the day as it ensures maximum security and can be utilized in averting potential terror attacks as well. Biometrics is slowly finding its way in many fields – border security control, banks, offices, hospitals, schools, airports.
In offices, deploying biometric attendance systems has proved to be successful in tracking employee attendance. Instead of punching a time-card, the employee is only required to put his hand or a finger on the fingerprint reader sensor. These systems eliminate buddy punching and give correct records of employee attendance and their time period in the offices, thus helping in payroll processing as well.
Even in hospitals, biometrics has provided great help and has made things a lot more convenient. More and more hospitals are inclining towards fingerprint access control systems as they ensure the safest process of verification and recording of attendance of its doctors, nurses and other hospital staff. Even iris recognition – another very authentic method of biometrics has been adopted by many hospitals to stall the abduction of infants. In this process, the iris of the doctors, nurses and the mother are recorded and thus it removes the possibility of the entry of any unauthorized person.
