Intuitionistic Fuzzy Id3: An Approach to E-Transactional Fraud Detection

As the E-commerce is growing rapidly day by day, the on-line transactions are becoming an integral part of our daily life. The authenticating of an On-line transaction has become an important issue. In this paper we have proposed fraud detection algorithm based on Intuitionistic Fuzzy Logic based and ID3 which will mainly work in Indian On-line Transaction Scenarios. We used the Intuitionistic Fuzzy Logic to consider the Cognitive properties of different attributes, so that the authentic transactions are not blocked and Frauds are not allowed. We have used this Intuitionistic Fuzzy Logic based tree to classify the transactions as fraud, doubtful or normal. Experimental results are tabulated which shows that the technique is more effective compared to the other techniques available in the literature.
