Abstract: The digitalization of banking systems has considerably improved customer accessibility but it has also increased the complexity and frequency of fraudulent activities. Legacy integrated fraud claim processing system is often manual and involves rigid workflow which cannot suffice the requirements for real-time fraud detection, reporting, and enabling the rectification process. This research aims to build a holistic risk-based fraud claim processing framework for secure banking applications that can limit the exposure to the vulnerabilities of banking systems. The proposed model focuses on real-time transaction monitoring, risk scoring algorithms, and machine learning-based claim prioritization to dynamically evaluate and process fraudulent claims according to its severity and impact. The architecture will facilitate automatic decision-making, and adaptive authentication technologies embedded to deliver intelligence-enabled security without undermining the quality of user experience. One of the major components of the system is a rule engine that can classify claim assertions based on behavioral discrepancies, transaction irregularities, and historical transaction records into low risk, moderate risk, and high risk claims. Various machine learning algorithms including decision tree and support vector machines will be evaluated to predict the probability of fraud occurrence and to model the claim resolution process. The framework’s efficacy and performance have been validated through a use case and experiment conducted on a leading global financial organization that demonstrated superior accuracy in fraud detection, a reduced claim processing time, and a considerable decrease in financial losses caused by fraudulent activities. Additionally, the proposed solution satisfies the compliance regulations of GDPR, PSD2, and PCI DSS that backs data confidence and integrity. This research articulates the need for an intelligent, dynamic, and machine learning-driven approach to fraud eradication that can help to maintain modern financial disruptive ecosystems.
