Abstract:
Counterfeit drugs are the one of most serious problems in pharmaceutical industry
nowadays. According to health reports of world health organization and the health research
funding organizations, nearly 10-30% of the drugs are fake in developing countries. This
problem is most prevalent in such areas like drug surveillance and regulation needs to be
improved and where drugs are in high demand, but mostly they remain unaffordable. When
comparing with traditional drugs theses counterfeit drugs can produce various side effects
to human health. Developing country like Sri Lanka also doesn’t have a proper way to track
and trace drugs or to protect from this threat using any other available methods. Because
counterfeiters can inject their counterfeit drugs in to drug supply chain wherever it’s
vulnerable within the chain. So, identifying this problem as a timely need author has chosen
to research and develop a proper system for counterfeit drugs problem by overcoming
drawbacks of existing systems.
This project, Know Your Drug system is designed and implemented as more transparent
and trustful way to track and trace the drugs and secure the drug supply chain from
counterfeiters. Implemented supply chain will overcome the trust barriers in the existing
drug supply chains where an administrator or any kind of third-party intruder cannot exploit
the system. Author has used a hybrid-blockchain system to approach and give solution for
these conditions. Furthermore, it has given a solution for data tampering issues facing when
using the private blockchains. Though, Know Your Drug system has developed more
towards general usage where manufactures, distributors, wholesalers and retailers come in
to play, this research paper will discuss how it is used to track and trace counterfeit drugs
in Sri Lanka according to Sri Lankan regulations and systems for the drug supply chain.
