Output PHASE OF BIO-METRICS

 Testing of processed data and give the access rights to the person. Here,
When any person scanned his/her finger print , computer will
store a Bio-logical featured pattern and compares it against the stored master-
key in its memory. And if it is matched, then permission granted else not.

Process PHASE OF BIO-METRICS

 Processes the input data. Here, computer takes the measurement of inputed Biological features.

 No two persons have same finger print. So, computer joins the points of that finger print features and make the pattern of it and it will store that pattern into its memory. Then computer compares this pattern against the master keys.

• e.g.: - Putting the tracing paper on Indian map, if we join Banglor, Chennai, Delhi, Hyderabad, Mumbai, Nagpur, Ahmedabad, Jaipur and Lukhnow drawing a line then by chance the original map is lost. Now if we want to know the distance between Ahmedabad and Bhavnagar for that we require the original one, which is drawn with the same measurement. But In this case, actual map is lost so we are helpless. Similarly, the finger print used by the computer to make its pattern is deliberately hidden. Thus, the security system does not allow any unauthorized person.

INPUT PHASE OF BIO-METRICS

 Using appropriate input device it will collect the data of the person’s
biological features. These features are known as the master key for
the computer.

 Let us put in a simple manner.

For recording and converting biometric traits to usable computer data, one needs an appropriate sensor (see table). Of course, costs can greatly vary for different sensors. However, we can't forget that many technical devices already have sensors built in, and therefore, offer possibilities to measure biometric features nearly free of cost.
