Product traceability is developed for years, various traceability schemes are formed based on RFID and two-dimensional codes, upstream and downstream information barriers are opened, and the following three problems exist in general: firstly, from the overall architecture, the traditional tracing scheme is a centralized storage mode, and has the defects of easy data tampering, opaque information and the like; secondly, in terms of a data carrier, a scheme of purely adopting the RFID is adopted, so that a consumer needs to use special equipment for tracing and inquiring, and the problem of inconvenience exists. By adopting the scheme of the two-dimension code, a consumer can conveniently inquire the data, but the data is very easy to forge, namely, commodities and digital assets in the physical world are difficult to correspond to each other; thirdly, the problem of commodity fleeing goods can not be solved by the existing tracing solution.

The mode of the two-dimensional code is adopted, so that a larger and wider counterfeiting space is provided for counterfeiters, and the traceability is changed into a paper talk; in addition, the single electronic tag mode is adopted, so that the real effectiveness of the product is difficult to be fundamentally ensured, and the similar electronic tags are more likely to be used for counterfeiting, thereby causing bad results. Therefore, the reliability of the whole tracing process cannot be guaranteed, the tracing authentication method is easy to counterfeit, and the problems of counterfeiting and faking are difficult to completely stop fundamentally in the conventional product tracing authentication mode.
