What is Biometrics Security
Every person has intrinsic physical and behavior traits. When we take a group of these traits to identify the person to allow him or her to get access to a prohibited sector it is broadly known as biometrics security system. It is actually derived from 2 Greek words, Bios meaning life and Metron meaning measure.
Biometric system is often used by the information technology and the software sector. They employ it often as an identity access management system. This system is capable of identifying the allotted individual in a group.
Biometric systems are broadly classified as behavior and physical. Physiological means related to our body. It ranges from fingerprints, face recognition, DNA, iris recognition, smell, hand and palm recognition and so on. Typing rhythm, voice recognition are the features of behavior part of the individual. Both of the traits can be employed together to formulate a biometric security system.
Parameters like universality, uniqueness, permanence, collectability, performance, acceptability and circumvention are used as human characteristics for the biometric security system. These parameters are used in proportion to formulate the biometric system to be enforced.
The biometric sytem has to methods. They are verification and identification. First time when a person uses the biometric system is perceived as enrolment. During this enrolment process the biometric examples of the person is collected and stored in the shape of a template in the biometric system’s database. When the person uses the system in future the biometric information will be noticed and determined with the info in the template caught in the time of enrolment. After the corroboration the person is identified and allowed access to the secured zone. Protection of the stored data in the biometric template and also the mechanism of retrieval of biometric data is very urgent for the system to function as wanted. The interface between the real person and the biometric system is the sensor. The sensor acquires all the mandatory data to process the access request. The unnecessary inputs are then filtered off. Then the information is processed to take the information required for the safety corroboration. Then a template with the removed info is made. Then this template is coupled with the stored template in the biometric database. Once the data is matched the person is given access to the requested security area.
Different analytical methods are used to gauge the performance of the biometric system. They’re false reject rate or false non-match rate, fake match rate or fake accept rate, crossover blunder rate or equal blunder rate, failure to capture rate, failure to enroll rate, template capacity and receiver operating characteristics. To have the ultimate biometric security system, you need to have the right sensitivity of the device. For this we need to have minimum false accept rate and minimum fake reject rate. Security system, you need to have the right sensitivity of the device. For this we want to have minimum fake accept rate and minimum fake reject rate.
Discrimination and hacking of the info of the biometric database are the major risks that have to be taken care of. The data in the database should be protected.
There is a risk to security for the owner of the biometric system and the secured items. There are probabilities of irrevocable damage cased to the owner by the miscreants.
Countries applying biometrics to an enormous extent are US of America, Brazil, Germany, Iraq, Japan, Great Britain, Australia, Canada and Israel. This is surely going to be the security parameter of the future.
