Thesis Abstract

Abstract
The rise of online transactions has brought about numerous benefits in terms of convenience and accessibility. However, with this increase in online activity comes the heightened risk of fraudulent activities. Detecting and preventing fraud in online transactions is crucial to safeguarding the interests of both businesses and consumers. Machine learning algorithms have emerged as powerful tools in the fight against fraud due to their ability to analyze vast amounts of data and identify patterns that may indicate fraudulent behavior. This thesis focuses on the application of machine learning algorithms for fraud detection in online transactions. The research aims to explore how different machine learning techniques can be utilized to improve the accuracy and efficiency of fraud detection systems. The study will involve the collection and analysis of transaction data from various sources to train machine learning models to detect fraudulent activities. Chapter 1 provides an introduction to the research topic, outlining the background of the study, problem statement, objectives, limitations, scope, significance, and structure of the thesis. Chapter 2 presents a comprehensive literature review on existing research related to fraud detection, machine learning algorithms, and online transactions. The review will highlight key findings, methodologies, and challenges in the field. In Chapter 3, the research methodology is detailed, including the data collection process, selection of machine learning algorithms, model training, and evaluation techniques. The chapter will also discuss the ethical considerations and limitations of the research methodology. Chapter 4 presents the findings of the study, including the performance of different machine learning algorithms in detecting fraudulent transactions and the factors influencing their effectiveness. The discussion in Chapter 4 will delve into the implications of the research findings, potential areas for improvement, and practical applications of the developed fraud detection system. Finally, Chapter 5 offers a conclusion and summary of the thesis, highlighting the key findings, contributions to the field, and recommendations for future research. Overall, this thesis aims to contribute to the ongoing efforts to combat fraud in online transactions by leveraging the power of machine learning algorithms. The research findings are expected to provide valuable insights for businesses and organizations looking to enhance their fraud detection capabilities and protect against financial losses and reputational damage.
