Security is an important concern for industries, diverse organizations, business sectors, etc., in the modern world. Currently, everyone stores personal and professional data in the cloud for long-term access because of its reliability, flexibility and performance. Some top-rated multinational companies (MNCs) have introduced their own cloud platform for storing their own data and providing payable access to the public. However, security risk is a major challenge in cloud platforms in regard to user data privacy and security. To overcome this issue, the proposed model incorporates cloud computing with blockchain for the secure transfer of user data. This process works in a comprehensive approach for creating an account using AWS EC2, creating smart contract solidity using DApp (Decentralized Application), creating user Metamasks with access policy creation, and generating hash code. The AWSCLI is used to run commands on Amazon EC2 (Amazon Elastic Compute Cloud) instances through a remote terminal program such as PuTTY or SSH. The PuTTY is an open source terminal emulator and is free. It permits the association with remote devices or computers using different protocols, such as login, SSH (secure socket shell) and telnet, to configure the smart contract truffle. The data transfer is performed using Ganache and Metamask, and Ganache is utilized to deploy contracts by setting up a personal Ethereum Blockchain. Metamask is a cryptocurrency software utilized to communicate with the Ethereum blockchain. It helps with smart contract interaction and the evaluation process after the process is displayed on a cloud platform in a secure way. The proposed model represents how the security of the cloud can be enhanced by using blockchain smart contracts.
