Medical compounding scanning code logistics tracking method

Abstract

The present application relates to the field of medicine cold chain logistics information technology, especially to a medical static dispensing code scanning logistics tracking method, the steps comprising: attaching a self-powered label on the outside of the preparation, reading the magnetic tunnel junction physical fingerprint and nanocrystal dot-deoxyribonucleic acid information to generate a reference hash value, and collecting temperature and humidity recursive environment hash chain at fixed intervals; when transferring, a challenge is generated by using satellite high-entropy random number, a second fingerprint is obtained, a zero-knowledge event proof is constructed by combining the reference hash value and the environment chain, and after a plurality of proofs are aggregated by dynamic programming, they are written into a distributed ledger; the state information of the wireless channel is synchronously grabbed to construct a dynamic graph, and the next node instruction and risk score are output by the graph neural network and the near-end strategy optimization. The present application realizes battery-free anti-cloning, tamper-proof cold chain monitoring and network interruption path decision, with low chain fee and high robustness.
