An Application of Blockchain to Secure the Conventional Product Authentication Management System

Products counterfeit is a multi-billion dollars market, and the growth of this field is high. There havebeen many technological enhancements like Radio Frequency Identification (RFID) and Encrypted QuickResponse (EQR) code. These technologies have been used to track down those products in the supply chaindownstream and identify products for authenticity. Under these circumstances, all existing solutions must rely ona central database for operating. The matter of this subject points out the drawback of single point of failure. As aresult, these systems are more prone to cyber-attacks. In some cases, supply chain insiders play as a bad actor ofthe system too. To prevent this, tracing concrete proof of provenance of transactions is needed. In addition,business operations require contract and consensus. These can be solved using blockchain technology. Asbusiness requires privacy and cannot rely on public network. Thus, the solution of this need requires to be builtenterprise blockchain environment.
