Evaluating Biometrics

Evaluating Biometrics

Biometric industry is one of the main industries which is growing rapidly in the recent years .The necessity of this industry occurred when there was drastic incident which took place in USA on twin towers on sep11 made to think about this industry. but still many of the industrialists are unwilling to put in into this evolving technology due to this the industries are producing products which are unsatisfied this is proven by the recent article which is published byWashington Business Journal “biometrics is an industry which is disjointed, and is the next evolution in security, with many organizations trying variety of things”.

Metrics and performance criteria:

Since biometrics deals about security system it should be done with high concentration and demanding to offer different credentials, authentications and other conformations   to the biometric systems. Different type of mechanism delivers different results which is viewed .and the best part of these are processed for captured for solutions whatever may be the methodologies .these biometric tools   performance can be evaluated by few words this can be explained by example when a client of censoring fingerprints who displays in portal as “0.0%false avoiding rates” And some other full-fledged standards maintained and this can act as a performance evaluators in the biometric systems. But three are very crucial in evaluating these performances which are quoted below.

False Match Rates (FMR):

FMR gives the ratio when the current user identification is verified with another registered identification of the current underlying system. it can be taken as the fake being is identified as  rightful user. This is the common error occurred and it easily solved with minimum control on error rates.

False Non-Match Rate (FNMR):

FMR is statistic used to measure biometric performance. Similar to the False Reject Rate (FRR), this is done when particular identification is not matched with the other registeredtemplate and huge false rate results may give zero production and also leads to client depression. 

Failure-to-Enrol Rate (FTE):

The rate that attempts to create a template from an input is unsuccessful. This is most commonly caused by low quality inputs. Like expandable characteristics which is given during identification process. That means for new client system is unable to deliver the process it affects the mental nature than physical nature.

For every procedure mostly three trails should be done and all the metric rates will create a force in different ways and this relies on no of iterations done on these processes. FNMR and FTE play a key role in accessing the biometric   routines and hence these two are very important.

Several methods for generating cancellable biometrics have been proposed.


All the above study indicates that the importance of biometrics is vast in the present day world and even it is clear that biometrics are playing a vital role in the daily routine of the human beings. In the present generation the usage of biometric systems for user authentication has become common. In providing security for the users from the fake users or hackers and attackers these biometric applications plays a lead character, that means the technology used is very important in proving required security for the end users. Because of the present society and with the usage of advanced technologies the frauds are also increased in advanced level.

These frauds can be addressed by using the biometric systems in a better way. Biometrics introduces better and sophisticated technologies that can provide good benefits for the users. There for day by day the importance and usage of biometric systems is increasing in the world. The popularity of biometrics is spreading in a wide range. Biometrics systems can secure data in a good manner and along with this even it can be worked in other areas where security is needed. The features of biometrics will become advanced in the coming generation due to the fastest establishment of advanced technologies in the world.
