In this seminar thesis you will get a view about the Data Mining techniques in financial fraud detection. Financial Fraud is taking a big issue in economical problem, which is still growing. So there is a big interest to detect fraud, but by large amounts of data, this is difficult. Therefore, many data mining techniques are repeatedly used to detect frauds in fraudulent activities. Majority of fraud area are Insurance, Banking, Health and Financial Statement Fraud. The most widely used data mining techniques are Support Vector Machines (SVM), Decision Trees (DT), Logistic Regression (LR), Naives Bayes, Bayesian Belief Network, Classification and Regression Tree (CART) etc. These techniques existed for many years and are used repeatedly to develop a fraud detection system or for analyze frauds.

What are the main areas of fraud covered?
The work covers four major areas: insurance fraud, banking fraud, healthcare fraud, and financial statement fraud.
What is the core objective of the research?
The objective is to analyze the literature to identify and categorize the most effective data mining techniques used for fraud detection.
Which scientific methodology was utilized?
The author employed a systematic literature review by filtering articles from databases like Google Scholar, ScienceDirect, and Springer Link, published between 2010 and 2016.
What topics are discussed in the main body of the work?
The main body covers basic terminology, a detailed classification of data mining applications (such as clustering and regression), and a comprehensive review of existing academic research on fraud detection.
Which keywords best characterize this work?
Key terms include Data Mining, Financial Fraud, SVM, Neural Networks, and fraud detection frameworks.
What are the most commonly used data mining techniques found in the research?
The research identifies Neural Networks (NN), Support Vector Machines (SVM), and Logistic Regression (LR) as the most frequently used and effective techniques.
Does the author propose a new framework?
Yes, the author develops a framework to present the relationship between the specific fraud area, the applied data mining application, and the chosen technical approach.
What is the significance of the "confusion matrix" mentioned in the review?
It is used to test the performance of fraud detection models by classifying outcomes into true positives, false positives, true negatives, and false negatives.
What is the main finding regarding real-time fraud detection?
The research notes that existing fraud detection systems are becoming increasingly close to real-world application, even when analyzing large, complex datasets in real-time.
