Blockchain-based Proof of Existence (PoE) Framework using Ethereum Smart Contracts

Abstract

In recent years, Blockchain, underpinned by distributed ledger technology (DLT) has been touted as the next disruptive technology with the potential to revolutionise various industry verticals and horizontals. Plagiarism and Intellectual Property Infringements of copyrights of artifacts, trade secrets, etc., are often fought in courts of law. There is an inherent need to adduce reliable evidence to establish a prima facie tort case or even beyond. In this paper we aim to leverage on the Blockchain technology to provide a digital transformation in the post-Covid world by offering a new platform to aid in the protection of one's intellectual property rights through a Proof of Existence (PoE) framework using Ethereum smart contracts. We have developed a seamless web platform to allow users experience a simple yet secure Proof of Existence (PoE) service by allowing the users to (i) certify, (ii) manage and (iii) view their documents securely through a digital portfolio. This PoE service leverages on the Blockchain characteristics to provide a reliable and transparent means to record a tamper-proof evidence of copyright information with timestamp as proof of existence for all its transactions through smart contracts.
