Fraud refers to earn wealth including property, goods and services through immoral and non-legal channels. Fraud has always been in action and experiences an increasing trend worldwide. Fraud in financial transactions not only leads to losing huge financial resources, but also leads to reduction in trust of customers on using modern banking systems and hence, reduction in efficiency of the systems and optimal management of financial transactions. In recent years, by emerging new technologiesofbankingindustry,newmeansoffraudarediscovered. Althoughanewinformationsystem carry advantages and benefits, new opportunities are made for fraudsters. The applications of fraud detection methods encompasses detection of frauds in an organization, analysis of frauds and also user/customer behavior analytics in order to predict future behavior and reduce the fraud risks. In recentdecades, employingnewtechnologiesinmanagementofbankingtransactionshasrisen. Banks and financial institutions inevitably migrated from traditional banking to modern online banking to provide effective services. Although, the use of online banking systems improves the management of financial processes and speeds up services to customers of institutions, but some issues would also be carried. Financial frauds is one of the issues which organizations seek to prevent and reduce effects. Inthispaper, anovelmachinelearningbasedmodelispresentedtodetectfraudinelectronic banking transactions using profile data of bank customers. In the proposed method, transactional data from banks are leveraged and a multi-layer perceptron neural network with adaptive learning rate is trained to prove the validity of a transaction and hence, improve the fraud detection in electronicbanking.
