药品安全直接关系到病人的生命健康，国家已出台严厉的打击措施，但假药问题仍屡禁不止，其中一个主要原因是缺少相应的技术手段对药品进行防伪管理。本文基于可信二维码，结合药品实际流通过程，为药品提供了一个安全可信的防伪系统，实现对制造商、经销商、药品本身的合法性认证，确实解决了药品防伪问题。

Drug safety is directly related to the life and health of patients. The state has issued stringent crackdown measures, but the problem of counterfeit drugs is still emerging.
