Cloud-based secure payment system with OTP and encrypted data storage

Abstract: The rapid growth of digital payment systems and e-commerce platforms has significantly increased the volume of online financial transactions. However, this growth has also led to a rise in cybercrimes such as phishing, OTP fraud, and unauthorized access to sensitive financial data. Traditional payment systems lack adaptive security mechanisms, making them vulnerable to evolving fraud techniques.
This project proposes a cloud-based secure payment system that integrates OTP authentication and encrypted data storage to enhance transaction security. The system ensures that every transaction is verified through a one-time password and simultaneously sends detailed transaction information to the user’s registered email. A security link is also provided to report fraudulent activities instantly to cybercrime authorities.
The proposed system focuses on protecting user data, preventing OTP misuse, and ensuring secure communication through encryption techniques. By leveraging cloud technology, the system provides scalability, real-time monitoring, and improved reliability. Overall, the system enhances security in digital payments, reduces fraud risks, and increases user trust in online transactions.
