    A Consortium Blockchain Model to Overcome Issues in the Global Patent Authentication and Management Process
    (Faculty of Computing and Technology (FCT), University of Kelaniya, Sri Lanka, 2021) Gunasekara, Prageeth Thilina; Rajapakse, Chathura
    Patent authentication and management is an important activity to protect the intellectual property rights of individuals and organizations globally. As the patents are territorial and the data management related to patent applications mostly happens with local intellectual property (IP) offices, the patent authentication and management (PAM) process is significantly inefficient and time-consuming on the global scale. Moreover, the data management issues in the patent process often lead to conflicts and legal actions among competing parties. Blockchain technology is widely recognized for its potential use in creating decentralized, secure, and transparent systems with immutable records. It hence seems to be a useful technology to overcome the issues in the patent domain. This paper explores the adaptability of blockchain technology in the patent domain. It presents the design of a consortium blockchain system, which is proposed as a solution to numerous issues stemming from inefficient data management. The proposed consortium blockchain design is based on the Ethereum architecture and is equipped with smart contracts to ensure the reliability of patent data as well as the real-time update of records. This paper further discusses the potential testing and validation strategies for the proposed model.

    Challenges of Adopting Blockchain Technology to Pharmaceutical Supply Chain – A Case Study from Sri Lankan Health Sector
    (Faculty of Computing and Technology (FCT), University of Kelaniya, Sri Lanka, 2021) Paththinige, Pavani Wasana; Rajapakse, Chathura
    Ensuring the transparency of pharmaceutical supply chains is an important task to control the adverse health effects of counterfeit drugs. Blockchain technology has been widely recognized among supply chain researchers as a useful emerging technology to enhance transparency and security of various supply chains. However, the adoption of the blockchain technology in pharmaceutical supply chains is still in its infancy with only a handful of research reported to date. This paper presents the details of a conceptual model developed to explore the challenges of adopting blockchain technology to manage pharmaceutical supply chain while combatting against the flow of counterfeit drugs. The proposed conceptual model, which is based on a comprehensive review of literature, encapsulates the complex linkages between seven influencing factors namely 1) Relative advantage 2) Upper management support 3) Human Resource 4) Compatibility 5) Cost 6) Complexity, and 7) Technological Infrastructure and Architecture. The factors evaluated in the framework interact and impact one another. The proposed framework can be utilized as a starting point for implementing blockchain applications in the pharmaceutical supply chain as well as by academics to develop, refine, and assess blockchain based research. As factors have been identified, practitioners will be able to develop a strategy for implementing blockchain in the pharmaceutical supply chain
