IPFS-Based Blockchain Solution for Secure and Efficient Data Sharing

Abstract

This study introduces a decentralized blockchain-based framework for secure data exchange within cloud environments. It employs IPFS to encrypt and fragment files into multiple hash codes, enhancing security. Access is restricted to registered cloud users, ensuring controlled data distribution. Blockchain technology upholds data integrity by securely logging transactions, making them tamper-resistant. Unlike centralized storage models, this decentralized approach eliminates single points of failure, improving reliability and security. By spreading data across multiple nodes, the system reduces risks from cyber threats and unreliable cloud providers. It also lowers computational and communication overhead, ensuring efficient data transfer. Additionally, it protects sensitive data from unauthorized breaches and cyber-attacks. The blockchain-IPFS fusion strengthens security and accessibility, allowing seamless, regulated data handling across diverse domains. Tailored to counter security challenges in cloud storage, the system ensures data confidentiality, controlled sharing, and restricted access. Its decentralized design fosters transparency, minimizes dependence on centralized entities, and mitigates security flaws. By utilizing blockchain’s immutable nature and cryptographic measures, this system enhances trust and ensures a fortified environment for data transactions. It mitigates risks linked to conventional cloud storage, offering resilience against data loss and cyber hazards. The system is optimized for performance, reducing latency and improving accessibility. Scalability is a key feature, supporting growing data storage demands. It guarantees data confidentiality, integrity, and availability, fostering secure cross-domain data sharing. Ultimately, this framework creates a secure, efficient, and decentralized solution for cloud storage and transfer, advancing data protection and accessibility
