Agricultural product electronic tracing supervision code generation method and apparatus thereof

Abstract

The invention provides an agricultural product electronic tracing supervision code generation method. The method comprises the following steps: S1. carrying out traceable supervision coding on an agricultural product, and obtaining a traceable supervision intermediate code; S2. compressing the traceable supervision intermediate code to obtain a compression code; S3. encrypting the compression code, and generating a unique agricultural product electronic tracing supervision code with one cipher at one time. According to the method and the apparatus of the invention, by utilizing an encryption algorithm, the compressed agricultural product traceable supervision intermediate code is subjected to encryption, the electronic tracing supervision code with 'one product one code' is generated, and unique identification and safe rapid supervision tracing of the agricultural product are realized.

Description

technical field [0001] The invention relates to a method and a device for generating an electronic traceability supervision code for agricultural products, belonging to the field of supervision and traceability of agricultural products. Background technique [0002] China is an important agricultural product producing and exporting country. The quality and safety of agricultural products has been a hot issue that the government and consumers have been concerned about in recent years, and the safety traceability of agricultural products has also been paid more and more attention. Establishing an agricultural product quality traceability system and promoting the construction of China's agricultural product safety system are important means to ensure the safety of consumers' edible agricultural products and enhance the competitiveness of agricultural products. The unified code is the basis for realizing the agricultural product traceability system, and the security of the trace...

Problems solved by technology

For example, the combination of product coding and process coding, and the agricultural product traceability code scheme based on geographic coordinates have long length, weak encryption or even no encryption, and are easy to be tampered with, forged and cannot be traced back. The uniqueness of the code, and when the domestic provinces, municipalities and autonomous regions develop their own agricultural product quality traceability systems, they have their own sets of coding methods for agricultural products, which are not uniform, and they are all printed by connecting a computer to a printer. For ordinary small enterprises in rural areas, it is a big test in terms of cost and network environment, and this method has poor mobility
