Design and Implementation of Grain Traceability Code Coding Scheme

Aiming at the problem of low traceability accuracy in the existing grain traceability system due to the bulk of the grain, combined with the GTIN coding standard in the GS1 system, a stage traceability code is set for each link of the grain supply chain to achieve positioning to specific links. Aiming at the problems of long length, low security, and confusing expression and format after encryption of existing traceability code, based on the designed stage traceability code, combined with the improved PRESENT encryption algorithm and format-preserving algorithm to encrypt, We obtained a sixteen-digit final traceability code and tested the coding scheme proposed in this paper, The test results show that the proposed scheme is effective and valuable.
