Revolutionizing Payment Systems: Integrating RSA-Encrypted NFTs in Blockchain for Cash-on-Delivery Transactions

In the e-commerce fields, our approaches consider to address the enhance security, trust, and transparency issues in cash-on-delivery (COD) systems. Handling the traditional risks and inefficiencies of current COD processes (e.g., cross-border transactions between the shipper and buyer/purchaser), this paper present an encryption-powered (i.e., RSA encryption) with Non-Fungible Tokens (NFTs) within a blockchain platform. This approach not only benefits the decentralized, immutable, and transparent as a nature of blockchain-supported technology but also protects the sensitive info with the added security layer of RSA encryption. The NFTs usages ensure the uniqueness and irreplaceability of each transaction, thereby offering a system that is secure, private, and efficient compared to the central-based storage in the current system. This paper represents a our effort in digital payment systems, providing a comprehensive solution that responds to the evolving challenges in e-commerce and sets new benchmarks for digital transaction security, privacy, and efficiency.
