Secure and Efficient Cloud Storage System with Deduplication and Compression Using Blockchain Technology

Cloud storage is becoming increasingly essential as data volumes continue to grow exponentially. However, traditional cloud storage systems face issues related to data redundancy, inefficient storage utilization, and vulnerabilities in security. This paper presents a novel approach to cloud storage that incorporates deduplication, compression, and blockchain technology. Deduplication removes redundant data, while compression minimizes storage requirements. Blockchain, known for its decentralized and immutable ledger, ensures data integrity and security. The results of this research demonstrate that the system effectively reduces storage consumption and provides a high level of security, outperforming conventional systems in terms of efficiency and protection against data breaches.
