SHARP2P: uma ferramenta P2P para sincronização e compartilhamento de arquivos e diretórios

Abstract

File sharing tools are becoming increasingly popular. The most common ways to share a file include cloud sharing services with data synchronization, where files placed in a directory are synchronized to other devices automatically. However, in these services, data is stored on third-party servers, subject to confidentiality issues. File sharing tools that use P2P (peer-to-peer) networks are also popular. However, in this set of applications, the shared data is available to the entire network, allowing it to be accessed by unknown users, in addition these applications to not perform directory synchronization. This context motivated the creation of SharP2P, a tool which proposes a decentralized way for synchronizing files and directories. The tool incorporates a permissions system that allows users to choose to whom the data is shared. To implement the proposal, a watcher was used, which keeps watching for changes in the shared directory, a messaging service for transmitting files, and a (broker) server, which assists in the initial connection between users. Finally, to evaluate the proposed tool, were successfully performed tests on connection tests between users, directory synchronization, change permissions, and files update.
