        abstract = {Growing interconnectivity among IoT devices has exposed deep-rooted weaknesses in conventional, server-centric authentication approaches. To tackle these vulnerabilities, this paper presents a decentralized file-sharing and authentication architecture grounded in blockchain principles. Unlike centralized systems that are prone to single-point failures, unauthorized intrusions, and data manipulation, the proposed framework distributes trust across a network of blockchain nodes, cloud servers, data owners, and data consumers. A multi-role governance model is enforced through cloud-level administrative controls, ensuring that access rights are granted deliberately and transparently. File contents are shielded using Advanced Encryption Standard (AES) encryption, with each file receiving a distinct encryption key. To prevent in-app exposure, decryption keys are dispatched securely via email only after administrative clearance. File integrity is continuously verified through hash-based mechanisms distributed across independent storage nodes, making covert tampering detectable and reversible. The outcome is a cohesive security ecosystem that pairs decentralized storage with rigorous access governance},
