Ongoing loan fraud is a source of concern for financial institutions, as it has a direct financial impact and also scares off customers. This pattern, which can be traced to the development of modern technology, the introduction of novel ideas, and the quickening pace of international connections, makes the detection of fraud an expensive endeavour. This article proposes a novel framework for enhancing the fraud detection of loan banking using data mining algorithms. The framework extracts a number of predictive analysis techniques for identifying loan fraud. Several methods employing a wide range of pipeline architectures have been tried in order to select the optimal champion model. Autotuning has also been used to find the best possible setting for the model’s hyperparameters. The results of the evaluation show that autoencoder with gradient boosting outperformed the other classification algorithms with an accuracy of 98.62%. The proposed framework has the potential to significantly improve the fraud detection process of loan banking, which can ultimately lead to better faster fraud detects rates by combining data mining techniques with dimensionality reduction strategies in the feature space.

Credit cards play an essential role in today’s digital economy, and their usage has recently grown tremendously, accompanied by a corresponding increase in credit card fraud. Machine learning (ML) algorithms have been utilized for credit card fraud detection. However, the dynamic shopping patterns of credit card holders and the class imbalance problem have made it difficult for ML classifiers to achieve optimal performance. This research project aims to develop a reliable credit card fraud detection system through a stacking ensemble method, integrating LSTM and Random Forest machine learning techniques. This approach aims to enhance fraud detection accuracy by leveraging the diverse strengths of both models. The system will undergo rigorous evaluation to ensure its efficiency in identifying fraudulent transactions while minimizing false positives. By combining the temporal sequencing capabilities of LSTM with the decision-making process of Random Forest, the proposed approach seeks to achieve heightened sensitivity to fraudulent patterns while maintaining computational efficiency. Ultimately, the objective is to bolster security measures and protect financial institutions and consumers from potential fraud risks.

As we know and living in the era of digital world, Credit card fraud is increasing rapidly by transactions of unauthorized or any fraudulent use of someone else information of credit card to purchase and obtain benefits of financial. The victims of credit card fraud may have severe repercussions. Financial losses, harm to credit scores, and the trouble of dealing with unauthorized transactions can all arise from it. Secure your card information, keep a close eye on your account activity, and alert your card issuer right away to any odd transactions if you want to prevent credit card theft. To help combat fraud, many financial institutions additionally provide extra security features like two factor authentication and fraud detection systems. To resolve these problem we developed a system of Credit Card Fraud detection by hybrid techniques of machine learning which combines supervised and unsupervised methods to improve the system of fraud detection. In this paper we are using machine learning algorithms like K Nearest Neighbor, Logistic Regression and XGBoost model and we had made a comparison of accuracy score with other different models by using the data of European Cardholders 2013, by that data we had make comparison and decided that which model is best for defining the fraud system of credit card.

Credit card fraud is a serious and growing problem. Due to a rapid advancement in the electronic commerce technology, the use of credit cards has dramatically increased. As credit card becomes the most popular mode of payment for both online as well as regular purchase, cases of fraud associated with it are also rising. In this paper, we model the sequence of operations in credit card transaction processing using a Hidden Markov Model (HMM) and show how it can be used for the detection of frauds. An HMM is initially trained with the normal behavior of a cardholder. If an incoming credit card transaction is not accepted by the trained HMM with a sufficiently high probability, it is considered to be fraudulent. At the same time, we try to ensure that genuine transactions are not rejected. We present detailed experimental results to show the effectiveness of our approach and compare it with other techniques available in the literature.

A blockchain network's economics and user confidence can be seriously harmed by fraud. Consensus algorithms like proof of work and proof of stake can verify the legitimacy of a transaction but not the identity of the people who are conducting or verifying it. On a blockchain network, fraud can still occur, as a result of this. One approach to fighting fraud is to make use of machine learning techniques. There are two types of machine learning: supervised and unsupervised. We use a variety of supervised machine learning techniques in this study to distinguish between legitimate and fraudulent purchases. We also compare decision trees, Naive Bayes, logistic regression, multilayer perceptron, and other supervised machine learning techniques in detail for this challenge

Every year, millions of dollars are lost due to fraudulent credit card transactions. To help fraud investigators, more algorithms are turning to powerful machine learning methodologies. Designing fraud detection algorithms is particularly difficult because to the non-stationary distribution of data, excessively skewed class distributions, and continuous streams of transactions. At the same time, due to confidentiality considerations, public data is uncommon, leaving many questions unanswered about the best technique for dealing with them. We present some replies from the practitioners in this publication. Un balanced ness, non- stationarity and assessment. Our industrial partner provided us with an actual credit card dataset, which we used to do the analysis. In this project, we attempt to develop and evaluate a model for the imbalanced credit card fraud dataset.

Klaassen in (Klaassen 2015) proposed a method for the detection of data manipulation given the means and standard deviations for the cells of a oneway ANOVA design. This comment critically reviews this method. In addition, inspired by this analysis, an alternative approach to test sample correlations over several experiments is derived. The results are in close agreement with the initial analysis reported by an anonymous whistlelblower. Importantly, the statistic requires several similar experiments; a test for correlations between 3 sample means based on a single experiment must be considered as unreliable.

The use of credit cards has expanded considerably as a result of rapid advancements in electronic commerce technologies. As credit cards become the most popular method of payment for both online and offline purchases, incidences of credit card fraud are on the rise. Transactions with Credit Cards continue to expand in number, capturing a larger share of the US payment system and resulting in a higher rate of stolen account numbers and bank losses. Improved fraud detection has thus become critical to the payment system's long-term stability in the United States. For several years, banks have deployed early fraud warning systems. Large-scale data mining tools have the potential to improve commercial practice. Scalable strategies for analysing enormous volumes of transaction data and efficiently computing fraud detectors in a timely way, especially for e-commerce, is a critical issue. Aside from scalability and efficiency, the fraud-detection task has technical issues such as skewed training data distributions and non-uniform cost per error, both of which have received little attention in the now-established ledge-discovery and data mining communities.

Fraud is an unlawful act committed by individuals, both from within and outside an organization, with the aim of obtaining personal or group benefits that directly harm others. Regional autonomy, which leads to the central government delegating authority to district/city areas, can also transfer the potential for fraud from the center to the regions. One of the government's efforts in preventing and detecting fraud is through audits; however, the performance of fraud detection is highly influenced by professional skepticism, auditor experience, and the limited time provided. This study aims to: (1) Analyze professional skepticism as an antecedent in an auditor's fraud detection. (2) Analyze the level of auditor experience in handling fraud, as not all auditors with experience uncover fraudulent activities. (3) Analyze the moderating role of time pressure in fraud detection. Data were obtained through observation, in-depth interviews, surveys, documentation, and the use of questionnaires. This research is a causal associative study. The total sample collected was 45 individuals, selected using convenience sampling. The results of this study indicate that: 1) Work Experience has a positive influence on Auditor's Ability to Detect Fraud. 2) Professional Skepticism has a positive influence on Auditor's Ability to Detect Fraud. 3) Time Pressure has a negative influence on Auditor's Ability to Detect Fraud. 4) Work Experience, Professional Skepticism, and Time Pressure collectively influence Auditor's Ability to Detect Fraud.

Now days, the analysis of the behavior of cardholders is one of the important fields in electronic payment. This kind of analysis helps to extract behavioral and transaction profile patterns that can help financial systems to better protect their customers. In this paper, we propose an intelligent machine learning (ML) system for rules generation. It is based on a hybrid approach using rough set theory for feature selection, fuzzy logic and association rules for rules generation. A score function is defined and computed for each transaction based on the number of rules, that make this transaction suspicious. This score is kind of risk factor used to measure the level of awareness of the transaction and to improve a card fraud detection system in general. The behavior analysis level is a part of a whole financial fraud detection system where it is combined to intelligent classification to improve the fraud detection. In this work, we also propose an implementation of this system integrating the behavioral layer. The system results obtained are very convincing and the consumed time by our system, per transaction was 6 ms, which prove that our system is able to handle real time process.

In recent years, escalating fraudulent activities have led to significant financial losses across industries, intensifying the critical challenge of fraud detection. This study introduces a novel hybrid model that combines artificial neural networks (ANN) with support vector machines (SVM) to construct a robust additive model for fraud detection. Emphasizing the synthetic minority over-sampling technique (SMOTE), our investigation addresses the imbalanced nature of fraud versus non-fraud transactions. The clear novelty of our research lies in the seamless integration of these two powerful tools, offering a comprehensive and effective solution to the challenges posed by credit card fraud detection. Furthermore, our study stands out by emphasizing the collaborative synergy between ANN and SVM, particularly through the integration of multiple kernels, which improves the adaptability and accuracy of the proposed hybrid model. We conducted a thorough examination of 284,807 anonymized transactions, placing special emphasis on comparing the hybrid approach's performance and showcasing its superiority over traditional methodologies in the realm of fraud detection.

The research evaluates all recent applications of machine learning (ML) and deep learning (DL) for detecting credit card fraud. The study details multiple approaches to develop fraud detection systems by exploring both data quality enhancement methods along with feature selection approaches and modeling strategies.  The implementation of advanced deep learning approaches LSTM together with CNNs leads to high real-time detection of fraud because they excel at detecting sophisticated temporal sequences. XGBoost ensemble methods used with AdaBoost and SMOTE methods make great strides in improving fraud dataset handling of class imbalance issues. The method which is known as federated learning currently attracts attention because it helps institutions to collaborate on separate model training without exposing their actual data. Problems persist with the current development of fraud detection models since they need adaptable models for various datasets while also requiring interpretation capabilities and functionality that adapts to changing deceit patterns. The development of privacy-preserving methods for fraud detection must continue because they need to achieve sufficient efficiency and security standards for real-time applications. Problems with scalability in addition to unclear detection methods and adaptability require new research directions that fill existing knowledge gaps.

With the rapid development of socialist economy, there are many financial payment tools in our life, such as various credit cards issued by financial institutions. Although its emergence has brought us a lot of convenience, but at the same time there are certain disadvantages. In recent years, the crime of credit card swindler is increasing year by year. In view of whether there is a fraud in the credit card, this paper uses SMOTE algorithm to balance the unbalanced data.

Fraudulent behaviors in Google Android app market fuel search rank abuse and malware proliferation. We present FairPlay, a novel system that uncovers both malware and search rank fraud apps, by picking out trails that fraudsters leave behind. To identify suspicious apps, FairPlay PCF algorithm correlates review activities and uniquely combines detected review relations with linguistic and behavioral signals gleaned from longitudinal Google Play app data. We contribute a new longitudinal app dataset to the community, which consists of over 87K apps, 2.9M reviews, and 2.4M reviewers, collected over half a year. FairPlay achieves over 95% accuracy in classifying gold standard datasets of malware, fraudulent and legitimate apps. We show that 75% of the identified malware apps engage in search rank fraud. FairPlay discovers hundreds of fraudulent apps that currently evade Google Bouncer detection technology, and reveals a new type of attack campaign, where users are harassed into writing positive reviews, and install and review other apps.

The goal of this research is to quantify data quality problems including fraud, within freqeuntly used market research panels. To this end, a 10 item fraud detection tool was created, and embedded into a survey in order to quantify fraud across these large market research suppliers. Data collection has completed on 2 large aggregators, and data will next be collected from 2 additional commonly used supply sources, following the same analyses.

In this paper, we introduce a methodology based on the zero-inflated cure rate model to detect fraudsters in bank loan applications. In fact, our approach enables us to accommodate three different types of loan applicants, i.e., fraudsters, those who are susceptible to default and finally, those who are not susceptible to default. An advantage of our approach is to accommodate zero-inflated times, which is not possible in the standard cure rate model. To illustrate the proposed method, a real dataset of loan survival times is fitted by the zero-inflated Weibull cure rate model. The parameter estimation is reached by maximum likelihood estimation procedure and Monte Carlo simulations are carried out to check its finite sample performance.
