a)
Biometric is a security system which allows a person to be authenticated and identified. It is all
based upon the personal data, which is unique and specific. Biometric system is the process of
authentication of personal information of a person. The aim of the system is to capture and store
the unique personal information of a particular person. It can be their face, voice, fingerprint,
eyes etc. This data is then compared to the previously stored data of various persons which are
stored in database.
Biometric system is secure with many kinds of cybercrimes, unauthorized individuals, frauds,
etc. These technologies made a huge change in oppose to terrorism activities and gradually being
implemented. Today the biometric system is the most reliable system because of true
identification and fast processing (unar, et. Al., 2014).
There are majorly two types of biometric systems
1. Physiological
2. Behavioural
Physiological – These measurements based on the physical features of a particular person which
mostly consist of fingerprints, shape of a hand, vein pattern, iris or retina identification, DNA,
blood, saliva etc.
Behavioural – Behaviour of an individual is being identified, the most common are voice
recognition, gestures, accent etc.
 Fingerprint – Fingerprint biometrics are very reliable and use full today, any individual
having different and unique fingerprint helps the biometric function to work properly and
make it faster than any biometric sections. The working principle of fingerprint
biometrics is based upon two special types of features which are core points and delta
points of finger (Labati, et. Al., 2015). These points are commonly referred to as
singularity points. The core point is mostly used as a reference point which is located at
the topmost point and the innermost point of fingerprint. Increasing in technology also
increase the security techniques which reads the fingerprint matching methods
 An automatic fingerprint identification system
 An automatic fingerprint authentication system
Fingerprint scanner is being used in various different places for example-
Office, blood banks, college, industries etc.

Advantages:
1. Fingerprint biometric system has high accuracy
2. Improve security
3. It is easy to use
4. It cannot be forgotten or lost
5. This biometric system reduces the operational costs
6. It requires small storage space in the database memory
Disadvantages:
1. It is not appropriate for children because of the size of children fingers changes
quickly
2. Fingerprint biometric can make an error in identification when the finger is wet and
dirty.
3. Systems are not that much accurate
4. It cannot be reset easily.
 Hand geometry – Hand geometry biometric is also very useful to enhance the security.
Basically, this is based upon the geometrical shape and size of the hand, shape of palm,
width and length of the fingers etc. Hand geometry biometric capture the image of the
hand by using a camera. The hand is being placed over on a plate and palm should be
