What is Biometrics?
With the help of information and communication technology, people can no longer go to the office court and sign the attendance register. Instead, it is becoming possible to control daily attendance and office access by using physiological, behavioral components through the relevant controls of various information technologies. Currently, many smart offices are using such technology in multiple ways. Have you seen such a modern office?
The science that usually deals with biological information is called biometrics. Biometrics identifies human behavioral characteristics. It works by unit or group during observation. Biometrics is a type of technique by which a person's physical constitution determines a specific person, behavior, characteristics, qualities, personality, etc. Computers to identify individuals or groups in the corner and monitor their entry process. This technology is used in science. In addition to accurate person identification, it is also used for automated audits, safety searches, and monitoring according to physical characteristics. Thus, biometrics is a method of identifying a specific person based on the structure or behavioral factors of different parts of the human body.
The word biometrics has been taken from the Greek words 'bio' (life) and 'metric' (to measure). Nowadays, biometrics security has become very popular. This method is used for safety in any place database or information system. In this method, passwords are used for those features of the human being which act as a unit.
Types of biometrics:
Types of biometrics methods based on body composition and behavioral characteristics are shown in the form of tables.
Physiological features: Body structure and physiological features include human face recognition, fingerprints, handprints, eyeballs and retina scans, DNA formation. Below is a description of:
Face Recognition :
Usage: Used to identify a suspect in a corner, to guard the entrance to a building or room. This method is used to ensure the security of digital data.
Advantages: This method is a relatively inexpensive technology and easy to use and it gives accurate results.
Disadvantages: Due to the difference in facial expressions, it is often difficult to identify the face in this method. This method is less effective in short hair, sunglasses, hats, scarves, beards, long hair, makeup, etc.
Advantages: The cost of this method is comparatively less and less time-consuming. It takes. The success of this method is almost 100% as the fingerprint never changes.
Disadvantages: If there is a wound or cut on the finger if the finger is dry or dirty, this method does not show proper results.
Advantages: This method is easy to use. In this case, a little memory is required.
Disadvantages: The installation cost of this method is high, the cost of the device is relatively high. It is not useful for arthritis or rheumatism. Its results are less subtle than fingerprints.
Usage: This method is used in financial institutions, important government institutions, military.
Advantages: This method takes very little time (1 to 10 seconds) to detect. The results of this method are comparatively more subtle than fingerprints or handprints. It also has a security identification system, which is permanent and visible.
Disadvantages: This method is very expensive and requires relatively more memory. This method is problematic for spectacle users. Using this method causes eye damage.
Advantages: The DNA method helps to identify the real culprit. If there is no defect in the method, then the success in this method of identification is 100%.
Disadvantages: The cost of this method is much higher. Profiling DNA samples from mixed samples is very difficult. The success of the operation is seen in the fact that the DNA fingerprint is one in the case of the co-twins. Lack of skills, expertise, and vigilance of the staff in the laboratory affects the results.
Advantages: This method makes it easy to analyze data.
Disadvantage: In this case, the password is often confused.
Advantages: This method is less costly to use and also takes less time to detect.
Disadvantages: This method cannot be used for those who do not know the signature. In addition, the results of this method are comparatively less than the fingerprint.
