IoT Based Blockchain Temperature Monitoring and Fake Medicine Prevention

he Target of today’s healthcare system is delivering medicine directly from the manufacturer to end-user. The pharmaceutical supply chain involves distributors, manufacturers, wholesalers, and customers. The biggest challenge related to this supply chain is temperature monitoring also as counterfeit drug prevention. Many drugs and vaccines remain viable within a selected range of temperatures. If exposed beyond this temperature range, the drugs do not work as intended. Many of the world’s top-selling medicines are sensitive and need cold-chain shipping, i.e., storing goods during a temperature-controlled environment. Keeping the drugs cold is an important a part of the availability chain that connects drug producers to patients. But storing the essential information associated with cold-chain shipping in centralized databases is often susceptible to manipulations or data hacks. Also, the present software doesn't have tracking capability of maintaining a full chain of identity. One of the most reliable solutions would be the integration of IoT sensors with blockchain. To store the essential information related to cold-chain shipping in a blockchain network so, it becomes impossible for the data to get manipulate by anyone unlike centralized databases.
