Design Of A Drug Anti-forgery And Tracing System Based On Lightweight Digital Signatures

Everyone knows that drug is a special commodity, and it is closely related topeople’s life and health. But in recent years, the fake drugs or inferior drugs on themarket emerge in an endless stream, which not only disturb the order of the drugmarket, but also harm the interests of consumers. In addition, fake drugs are notconductive to the patient treatment, and even cause a great threat to patient’s life.Driven by the high profits, some businessmen produces more and more technologyand methods to manufacture fake drugs or inferior drugs. Thus the supervision of therelevant departments becomes more and more difficult, and the situation is becomingmore and more serious.In order to effectively deal with above problems in the pharmaceutical field, thispaper propose a method of applying digital identity to pharmaceutical field, to achievethe goal of anti-forgery, tracing and the flow of drugs. And then, this paper designs adrug anti-forgery and tracing system based on lightweight digital signatures andInternet of Things, unify the country’s pharmaceutical, build a national verificationplatform.In the beginning, this paper analysis the problems and shortcomings of theexisting drug anti-forgery systems, demonstrates the advantages of JUNA lightweightdigital signature technology and digital identities for drug anti-forgery and tracingsystem. The digital identities generated by JUNA has only16characters of whichhides the private key of a manufactory and the drug information, especially the drugunique number, and is directly printed on the drug label with coverage but no chip. Inthis way, this system can effectively solve the problem of key security, high cost,environmental pollution and poor usability of the digital security systems.Then, through the demand analysis of the system from the consumer, drugmanufacturers and middlemen perspective, the general plan of design, it analysis andwork out six modules for building system, they are data management system, digitalidentity management system, the flow direction track system, the source tracingsystem, drug verification platform system and reporting system. Meanwhile, itanalysis the specific implementation process for the six modules one by one, andgrasp system on the whole according to the specific functions and implementationprocess of the six modules and the implementation process of the whole model isanalyzed in detail. In this way, this paper builds out a mobile phone as a sensor, thenetwork as a hub, a system based on Internet of Things which can achieve druganti-forgery, source tracing and flow direction track.In the last, this paper demonstrates the system’s safety and availability, andmakes a comparative analysis with drug regulatory code. A high ease of use, securityand good performance of this system is proved.
