Abstract
Cloud computing is a relatively recent technological development that has steadily gained popularity over the last few years. The data sharing between legitimate entities in peer-to-peer (P2P) file systems in the cloud is the most challenging task. Nowadays, many individuals utilize document destruction programs. Sharing files created with these programs is one way for individuals to make money online. Some websites, like Chegg and Scribd, provide a forum for academics and freelancers to share their work with the public. To participate in these programs, the users first become members. And those who wish to access the files must still pay for the application rather than the original author. In this chapter, we developed a novel approach for a secure file-sharing system called blockchain-enabled and cloudlet-based networks (BCECBN). It integrates a blockchain for secure transactions and access to shared files. The proposed model is protected against various attacks performed by the adversary. In addition, it provides a solution for the above-discussed examples; users may easily share and trade data with one another and save and share data over the internet with no effort. In addition, this research will examine a cloud-based secure file-sharing system and exchange the data using digital media. Each user performs a transaction along the blockchain to get access to the files.
