Enhancing fraud detection and forensic auditing through data-driven techniques for financial integrity and security

摘要

Financial fraud remains a significant challenge in global economies, threatening the integrity and security of financial systems. Traditional fraud detection and forensic auditing methods often fail to keep pace with increasingly sophisticated fraudulent schemes. This review explores the role of data-driven techniques in enhancing fraud detection and forensic auditing to ensure financial integrity and security. Leveraging advanced technologies such as big data analytics, machine learning (ML), artificial intelligence (AI), blockchain, and robotic process automation (RPA), financial institutions can identify fraudulent activities in real time, improve predictive accuracy, and strengthen risk assessment frameworks. Big data analytics enables the processing of large volumes of financial transactions to detect anomalies and suspicious patterns, while ML algorithms provide adaptive fraud detection by recognizing evolving fraud tactics. AI-powered natural language processing (NLP) enhances forensic investigations by analyzing unstructured financial data, including emails and contracts, for signs of misconduct. Blockchain technology ensures transaction transparency and minimizes risks associated with identity fraud and double spending. Additionally, network analysis techniques improve the detection of fraudulent connections and collusive activities in financial networks. Despite the advantages of data-driven approaches, challenges such as data privacy concerns, implementation costs, and the continuous evolution of fraudulent tactics require adaptive regulatory frameworks and ethical considerations. Successful case studies demonstrate the efficacy of AI-driven fraud detection models in financial institutions, highlighting the importance of integrating data-driven methodologies into forensic auditing. This study emphasizes the need for financial institutions and regulatory bodies to adopt innovative fraud prevention strategies while maintaining compliance with governance and security standards. Future research should focus on developing scalable and interpretable AI models to enhance financial crime mitigation. By integrating advanced analytics with regulatory oversight, financial institutions can reinforce fraud prevention mechanisms and safeguard global financial systems against illicit activities.
