From Centralized Clouds to Decentralized Solutions: A Blockchain-Based Approach to file Sharing

Data security and privacy are growing concerns as cloud storage becomes integral to managing and sharing files online. This proposed work addresses these challenges by developing a blockchain-based file-sharing system that ensures secure, decentralized control over data. The system leverages blockchain technology to provide tamper-proof records, real-time access control, and file-sharing transparency. By using encryption mechanisms and smart contracts, the system ensures that users can manage, share, and revoke file access securely. This solution offers enhanced data integrity, privacy, and user empowerment compared to traditional cloud platforms.
