Research And Development Of Traceability System Of Agricultural Products Based On Security Two-Dimensional Code

With the rapid development of the socialist market economy and the further improvement of the national economic level,people's demands for food safety are getting higher and higher.As for the quality of agricultural products closely related to the people's life,the safety problem is becoming more and more Focus.From the general situation of the current agricultural market,consumers can hardly understand the relevant agricultural products from the cultivation,processing,transportation and sales at all stages of the detailed information,which to some extent not only harm the legitimate rights and interests of consumers,For some fake and shoddy producers to provide opportunities for speculation.Therefore,the establishment of agricultural products traceability of the new market mechanism has become the current social consensus.Based on the analysis of two-dimensional code and data encryption and other related technologies,combined with the advantages and disadvantages of the traditional anti-counterfeit traceability model,a new anti-counterfeit source model based on RSA encryption algorithm is constructed.Based on the ciphertext compression Algorithm and the real project as the application scenario,the related system construction is expatiated and realized in detail.The main work of this paper is as follows:1.A new anti-counterfeit source model based on RSA encryption algorithm is proposed and constructed.By using the advantage of two-dimensional code in data transmission and recognition,the model is used as the core information carrier of new anti-counterfeit traceability model,and its production,storage,Transport,sale and query and other related operations to merge,to sweep code instead of the traditional anti-counterfeit source model in the plaintext information exchange mode,while changing the traditional cumbersome mode of operation,by asymmetric encryption algorithm in the RSA encryption algorithm To the model,to enhance the security of the new security model and reliability.2.A method of generating 2-D anti-counterfeiting codes based on ciphertext compression is proposed.By constructing the anti-counterfeit traceability model based on RSA encryption algorithm,the security of the traditional model is improved,and the problems in the application are analyzed systematically.Aiming at the problem of low efficiency of security code generation caused by redundancyof ciphertext information caused by the increase of key length in the process of generating RSA code based on RSA encryption algorithm,ciphertext information is preprocessed by referring to data compression algorithm,And then proposed a ciphertext compression based on the security of two-dimensional code generation method,and then through a series of theoretical exposition and experimental testing,the feasibility of the improved methods discussed and related performance verification.In this paper,the new anti-counterfeiting model and the improved anti-counterfeiting two-dimensional code generation method of integration,the new agricultural products anti-counterfeit traceability system,the actual demand-oriented,through the core anti-counterfeiting system functions and other related functions of the integrated design,And then carries on the concrete realization and the practical application after the fusion new anti-counterfeit model.
