Description
Technical Field
The invention relates to the technical field of data processing, in particular to a method for processing source tracing data.
Background
A traceability mechanism is established for regular tobacco commodities circulating in the market, and a good prevention effect can be achieved for fake and counterfeit commodities. The tobacco commodity tracing technical scheme commonly used at present is that two-dimensional codes are printed on different packages (box packaging, strip packaging and box packaging) of commodities, and corresponding manufacturer information and circulation information are traced through identification of the two-dimensional codes. In practical application, we find that there are certain technical defects in this operation mode: 1) in the process of warehousing and logistics, if the circulation information of commodities needs to be obtained in time, two-dimensional code scanning, identification and recording are required to be carried out on each package manually, so that the labor cost of information tracing and recording is increased undoubtedly, the efficiency is low, and the method is not feasible basically under the condition of more cargoes; 2) the two-dimensional code is printed pattern information, and basically has no technical threshold for imitating the two-dimensional code, so that once the two-dimensional code on the commodity package is copied, counterfeit and shoddy commodities can be successfully mixed into the circulation field, and traceability information can be successfully obtained.
In order to solve the technical defects, the following improvements are made on the existing tobacco product traceability technical scheme: 1. radio Frequency Identification (RFID) tags are used for replacing original two-dimensional codes on the boxed commodities, and the RFID tags have a long-distance communication function, so that Identification information of all boxed commodities can be acquired in real time by only providing one corresponding RFID tag reading device in the warehousing and logistics processes, and manual code scanning operation one by one is not needed; 2. near Field Communication (NFC) tags are used for replacing original two-dimensional codes on the strip-packaged commodities, and because the NFC chip adopts ciphertext data storage and has an encryption/decryption function, a legality verification mechanism based on a security key and a security algorithm can be realized between a system and the NFC tags, and a technical threshold for breaking the mechanism is very high, so that the difficulty in realizing counterfeit and shoddy commodity copying through a non-formal channel is greatly improved, and the security of a tracing system is enhanced; 3) when the commodity is packaged and delivered from a factory, the related box-packaged RFID tag, the strip-packaged NFC tag and the box-packaged two-dimensional code data are subjected to associated binding, and the binding relation is stored in a commodity tag binding database, so that all tracing information associated with any one data item can be obtained at any time after the commodity is delivered from the factory; 4) in the circulation process of the boxed, stripped and boxed commodities, the information of the time, the position and the processing mechanism of the current circulation is collected once to form corresponding boxed, stripped and boxed circulation data every time the circulation is carried out, and the collected boxed, stripped and boxed circulation data are stored into corresponding boxed, stripped and boxed commodity circulation databases. Based on the improvements, a more complete and more authenticity-guaranteed traceability mechanism can be provided for the final client.

First legality verification and source tracing data processing flow
The process comprises the following steps: and reading the identification information of the strip NFC label of the current commodity to generate corresponding second identification data, and performing second legality verification processing according to the second identification data, wherein if the second legality verification processing is successful, performing second commodity information traceability processing according to the second identification data to generate corresponding second traceability data.
