Identifying an enemy committing fraud is a major fear to all business, schools, colleges, organizations, governments etc. Recently, the most used applications for prevention or detection of enemy committing fraud are interference detection systems. Biometrics technology is simply the measurement and use of the unique characteristics of living humans to distinguish them from one another and it is more useful as compared to passwords and symbols,sign, indication, signal,hint as they can be lost or stolen, so we have to opt the technique biometric authentication. The biometric authentication provides the ability to require more request of authentication in such a quick and easy manner that users are not disturbed by the additional requirements. In this paper, I have prearranged a brief introduction about biometrics. Then I have prearranged the information regarding the interference detection system and finally I have proposed a method which is based on fingerprint recognition which would allow us to detect more efficiently any misuse of the computer system that is running.
