Our project Credit card fraud detection presents a survey of various techniques used in credit card fraud detection mechanisms and evaluates each methodology based on certain design criteria. Fraudulent transactions are scattered with genuine transactions and simple pattern matching techniques are not often sufficient to detect those frauds accurately. Implementation of efficient fraud detection systems has thus become imperative for all credit card issuing banks to minimize their losses. Many modern techniques based on Artificial Intelligence, Data mining, Fuzzy logic, Machine learning, Sequence Alignment, Genetic Programming etc., has evolved in detecting various credit card fraudulent transactions. A clear understanding on all these approaches will certainly lead to an efficient credit card fraud detection system.


The Traditional detection method mainly depends on database system and the education of customers, which usually are delayed, inaccurate and not in-time. After that methods based on discriminate analysis and regression analysis are widely used which can detect fraud by credit rate for cardholders and credit card transaction for a large amount of data it is not efficient.



In the proposed system, high amount of losses due to fraud and the awareness of the relation between loss and the available limit have to be reduced. Number of fraud will be deducted and the number of false alert has to be minimized which consumes less time and takes no physical effort. The fraud is detected based on the customer’s behavior. A new classification problem which has a variable misclassification cost is introduced.
