An implementation of secure storage using blockchain technology on cloud environment

Abstract

Data generation and consumption have significantly increased recently, necessitating the need for secure and dependable file storage
solutions. The vulnerability of current centralized storage solutions to data breaches and hackers compromises the security and
integrity of user data. These problems may have a workable solution in a decentralized file storage system. In order to offer a secure
and dependable storage solution, this paper proposes a blockchain-based file storage (BBFS) system that takes advantage of features
like immutability, transparency, and security. Any user can upload unlimited files (one at a time) with this proposed system. Users can
download and access those files on their machines as well as all other peers. As soon as a peer uploads a file, it is placed in a block
along with the user name, file size, and file information. It is not possible to change or remove these blocks because they are added
to the current blockchain. These blocks can be connected with cloud storage, giving users a safe place to store and access their files
that cannot be altered. By integrating this proposed system with cloud storage, customers can take advantage of the scalability and
security of cloud services as well as the immutability and security of blockchain. The proposed system addresses the cost and scalability roblems that make to be widely applicable.
