Blockchain based Mechanism for Cloud Security

Abstract

As cloud-based data storage becomes increasingly prevalent, data breache risks and compromises of data grows. Data can be altered, and malevolent actors could take advantage of this. Clients require cloud services for different variety of applications. Cloud Service Providers ensure that the client data is correct and trustworthy. To address the issue, this paper proposes a solution that utilizes encryption and data verification to enhance data integrity and reduce vulnerability through the use of blockchain technology. Specifically, the proposed approach involves encrypting data and storing it on the Ethereum blockchain, allowing clients to quickly determine whether their data has been tampered with before the cloud service provider becomes aware of any potential security breaches. Even in cases where the data has been compromised, the proposed system enables clients to auto-verify data integrity, providing greater peace of mind and enhanced security. Overall, the proposed solution represents a promising approach for enhancing the security and integrity of data stored in cloud, and could be of significant value to individuals and organizations alike. This paper outlines the standards of data security and its ground-level implementation. The suggested system relies on a back-end service that uses a private cryptocurrency and does not require any advanced setup procedures. A wallet setup for the selected coin by the client is needed.
