DESIGN AND IMPLIMENTATION OF COMPUTERIZED FRAUD DETECTION SYSTEM IN BANKS

ABSTRACT

Banks deal essentially on cash, financial instruments and other documents, which are generally negotiable and easily transferable in nature. Based on sudden and very noticeable increase of fraud and crime in the financial sector which results in loss of billions of pounds and dollars would wide annually for over a long period of time, several modern automated techniques in detecting fraud and crime are continually being developed and applied to many financial sectors.

Financial detection system involves monitoring the behaviour of population of users in order to estimates, detect or avoid certain undesirable behaviours.

This project work presents and preview the total survey or techniques used in excessive fraud detection, telecommunication fraud detection, write – ff accounts receivable fraud detection and computer intension detection in order to develop a more efficient and comprehensive fraud detection system.

A fraud detection system was designed using log down methodology.
