Secure Multi Level Encryption with Blockchain in Distributed system

Abstract

As we technologically progress, it is becoming extremely common for both businesses and
individuals to use cloud storage services like Google Drive, Dropbox, iCloud and Amazon for storing their
files. These services offer them the convenience of storing and retrieving their files from anywhere in the
world using the Internet at relatively low costs, but they have introduced their own security and privacy
issues because of the way these files storage systems are implemented.
In this paper, we draw inspiration from the Blockchain distributed ledger technology and various file
distribution protocols to explore blockchain as an alternative strategy for file storage that offers security,
privacy and reliability. For implementation, we look towards the powerful IPFS, offering node distribution.
We design and implement a basic prototype of the suggested strategy, and discuss the results and the
challenges of the approach.
