Blockchain-Based Implementation for Integration of DNA Profiles Information Systems

Blockchain has been a new technology that involves an emergent evolution of many areas, particularly in finance, healthcare and supply chain. Due to its remarkable features including immutability, decentralization, peer-to-peer networking and capability to corporate with data protection and privacy, it is attractive to system integration. In traditional system integration architecture, a central mediator with a silo to store transactions stands in the center of integration to provide trust and transparency for participated systems. Hence existing central mediator could become a possible target of Distributed Denial of Service (DDoS) cyberattack and single point of failure. This paper presents a blockchain-base system architecture and its implementation for system integration which doesn't need a central mediator. The blockchain-based system has been implemented using Ethereum Blockchain in compliance with the General Data Protection Regulation (GDPR) standard to support the integration of DNA profiles information systems.
