Recently, a new personalized model has been developed to prevent credit card fraud. This model is promising; however, there remains some problems. Existing approaches cannot identify well credit card frauds from few data with skewed distributions. This paper proposes to address the problem using a binary support vector system (BSVS). The proposed BSVS is based on the support vectors in the support vector machines (SVM) and the genetic algorithm (GA) is employed to select support vectors. To obtain a high true negative rate, self-organizing mapping (SOM) is first employed to estimate the distribution model of the input data. Then BSVS is used to best train the data according to the input data distribution to obtain a high detection rate. Experimental results show that the proposed BSVS is effective especially for predicting a high true negative rate.

Banking industry is very tight competition in all aspects. Results review from some literatures: journals and empirical data indicates that the banking industry has been applied information technology in order to provide excellent service to customers in the form of electronic transactions such as ATM, sms banking, e-commerce and so forth. Based on Bank Indonesia reports, the type of electronic transaction has been growing very rapidly between the transaction and Bilyetgiro Elekteronik Checks, ATM, Credit Card, Account Card Based (ATM and Debit Cards), Electronic Money, Delivery Chanel and RTGS. Those above transactions are relating to the Technology Information System and Integrated System. Integrated system is the combination of Hardskill which focus on knowledge and more to the integrity softskill (shidiq, trustworthy, tablig, fathonah). Islamic banks are ready to face competition both nationally and internationally, primarily face competition from the aspect of Integrated Systems. Bank Syariah Mandiri (BSM) developed e-banking features on an ongoing basis, among others
