Blackbox: Distributed peer to peer file storage and backup

摘要

With emergence of the latest technology, need for digital documents, images and medias has greatly increased. On the other hand, there has been great demand of protecting those documents. The researchers proposed several approaches to protect those valuable documents. The two most exciting available approaches are to remove the devices and online storage. However, there is problem occurring with those external devices because they are taking longer time for burning and copying the data files. In addition, there is huge possibility of data loss when burning and copy the files. Online storage provides the reasonable solution, but it is costly when storing the large amount of data. This paper introduces the novel idea of a back-up file system that allows users to store the files on extra disk space. Thus, the Black-box is safe idea to backup the secret and valuable documents. The Black-box approach is supported by redundancy mechanism that involves the erasure coding and replication. The redundancy mechanism also improves the storage and computational capacity. The proposed idea is validated using MATLAB simulation.
