Secure File Sharing using Blockchain-Based Frameworks
N S Vasanth, Selva Jothi M, S. Indhu Pavithra · 2025
With growing concerns of data security and privacy related to digital file sharing, this research paper proposes a framework that strengthens secure file sharing across heterogeneous platforms. The solution exploits blockchain technology in combination with attribute-based encryption to protect anonymity of users and ensure data integrity. Blockchain, being a decentralized ledger, manages access without any centralized system, and the smart contracts define rules regarding file access and usage. The framework minimizes the risks associated with traditional methods by storing access permissions securely on the blockchain. Compared to the existing solutions like cloud-based encryption, End-To-End Encryption (E2EE), Attribute-Based Encryption (ABE), and Peer-To-Peer (P2P) file sharing, this approach provides better security, privacy, and reliability. This work addresses modern challenges in digital file sharing, providing a trustworthy and robust solution for secure communication.
