Abstract
With the rapid development of the social economy, our lives are flooded with all kinds of counterfeit products. The public's attitude of greedy for petty and cheap has encouraged unscrupulous manufacturers to take advantage of the opportunity to provide low-cost counterfeit products, suppress the profits of legitimate manufacturers, and also make the public lose confidence in the quality of the products. At present, the most widely used anti-counterfeiting system based on QR codes on the market. However, existing traceability systems are still mostly built in a centralized manner, and the central agency provides trust guarantees, but the public still has great doubts about the credibility of the central agency. The introduction of blockchain technology can perfectly solve the lack of existing architecture and the environment. In this research, we propose an IoT-based traceable drug anti-counterfeiting management system, a comprehensive plan from drug research and development, certification, production to sales. The framework we propose meets the requirements of information security for data integrity, resistance to replay attacks, irreversible information, and non-repudiation.
Highlights
As we known, from fake hairy crabs to fake cigarettes, fake wine, and fake medicines, counterfeit and inferior products have become a tumor in society
SYSTEM STRUCTURE In this research, we propose to use the Elliptic Curve Cryptography Digital Signature Standard (ECDSA) to design an Internet of Things (IoT)-based traceable drug anti-counterfeiting management system
The material supplier, the drug administration, the drug manufacturer, and the drug distributor register with the blockchain center and obtain the public and private keys for the ECDSA signature
Summary
From fake hairy crabs to fake cigarettes, fake wine, and fake medicines, counterfeit and inferior products have become a tumor in society. The combination of the two characteristics of nonfalsification of blockchain technology and traceability of transactions can completely eradicate the problems of counterfeit and inferior drugs in the process of drug research and development, production, and transportation in the supply chain. It has the following characteristics: First, the production process is recorded in the chain. After completing the finished product inspection, the employees use handheld devices or set up automatic assembly line equipment to encrypt the anticounterfeiting information and packaging records with the company's private key to the blockchain and time stamps for storage, and cannot be forged or tampered with. The history of drug production and circulation can be traced completely, and a third party can verify the drug at any time to achieve the effect of drug anti-counterfeiting
