Analysis of Blockchain Architecture in File Sharing Management for Tertiary Institution

Abstract

The aim of this paper is to analyze the sharing and management of files in a tertiary institution using blockchain architecture. It is expected to enable an online system that could provide a decentralized architecture for multiple transfers and sharing of files amongst participants, to design a system that can provide data integrity and security of files using IBM Blockchain technology, to provide a system that can allow multiple user and multiple transactions at once. The research was motivated because of the security challenges associated with existing system which include: delay in transfer and sharing of files, much authority and task given to a single user in a centralized system, high risk of attack and loss of files, reduced speed of file transfer and file access/retrieval, limited number of users per time. Methodology adopted was Object Oriented Analysis Design Methodology (OOADM) in conjunction with Unified Modeling Language (UML) and IBM Blockchain Technology while the programming language used was HTML, CSS, Java and Node Js. The result after design was a decentralized cloud based file sharing and management system that enables multi-shared, replicated and permissioned transactions amongst participants in a network.
