Abstract : The proposed decentralized storage system is designed to overcome the limitations of traditional cloud storage by combining InterPlanetary File System (IPFS), Ethereum blockchain, and advanced encryption techniques. The architecture ensures secure, transparent, and user-controlled file management without relying on centralized servers. Files are encrypted using Attribute-Based Encryption (ABE) and Chebyshev Polynomial Encryption to enforce fine-grained access control and confidentiality. Encrypted files are fragmented and stored across IPFS nodes, generating unique Content Identifiers (CIDs) that are immutably logged on the Ethereum blockchain via smart contracts. These smart contracts automate access control, file ownership verification, and audit trails, ensuring tamper-proof and transparent operations. A Django-based backend and web portal frontend enable seamless user interaction and file handling. Optional AI-based intrusion detection enhances system reliability by monitoring unauthorized access attempts. The integrated framework delivers decentralization, immutability, scalability, and user empowerment, offering a secure alternative to conventional storage models. This architecture demonstrates the potential of blockchain and distributed systems to revolutionize data privacy, integrity, and ownership in next-generation storage solutions.
