Strengthening Cloud Data Privacy and Integrity Using Blockchain Technology

Cloud computing has transformed data storage and access with flexible and scalable solutions. However, its dependence on third-party services poses significant concerns regarding data privacy and integrity. To tackle these concerns, blockchain technology known for its decentralized structure and tamper resistance offers a promising security enhancement for cloud environments. This paper explores and evaluates various blockchain-based mechanisms for securing cloud data and proposes a hybrid model that integrates blockchain with existing cloud infrastructures. Leveraging consensus protocols and cryptographic hashing, the proposed approach aims to mitigate data breaches, unauthorized access, and tampering. A practical implementation demonstrates the model’s effectiveness in fostering trust, transparency, and reliability in cloud services.
