The present invention relates to the field of data processing technology, and discloses a drug data matching method, device, equipment and storage medium. By matching the drug identification information in the drug input data from the drug standard library, if no match is found, the drug production information is continued to be used to match from the drug standard library. If a match is found, the specification information in the input data and the matched standard drug data is standardized and then matched. If the match is consistent, it is determined that the input data is successful, otherwise, the match fails. The above method is used to achieve drug data matching. Since two matches are set, the parameter dimensions of each match are different, thereby improving the accuracy of drug data matching correction, while also reducing the amount of data processed at one time, and improving matching efficiency. In addition, the present invention also relates to blockchain technology, and drug data can be stored in the blockchain.
