Abstract:
In the rapidly evolving digital economy, web-based payment systems are critical to global commerce, necessitating robust frameworks to ensure security, reliability, and compliance. This research proposes a comprehensive framework aimed at addressing these multifaceted challenges inherent in online transactions. The security component integrates SSL/TLS for secure data transmission and advanced authentication mechanisms such as REST API with JWT, IP/domain binding, and two-factor authentication. Pattern recognition techniques for anomaly detection, strict authorization protocols, and real-time fraud detection systems further enhance security, alongside data confidentiality measures like encryption and masking, and rigorous input validation and sanitization. To improve operational reliability, the framework incorporates mechanisms for dispute detection and chargebacks, detection of transaction failures and incomplete payments, duplicate payment protection, and an efficient refund process. It also focuses on system robustness and efficiency to handle high transaction volumes and address latency issues. Compliance with regulatory standards, including PCI DSS, GDPR, and OWASP Top Ten, is a core aspect, ensuring adherence to best practices and legal requirements. By examining current practices and identifying gaps, this study provides actionable insights for seamless integration and explores innovative approaches such as blockchain technology and artificial intelligence. The proposed framework aims to fortify webbased payment systems against emerging threats, ensuring trust and regulatory adherence in the digital payment landscape
