Design And Implementation Of A Costly Seafood Traceability System

With the development of information technology and logistics industry and theprosperity of sales market, people have higher requirements of the quality of products.In recent years, there have been more and more costly food traceability systems. Andcostly seafood is more and more popular, along with the characteristics such as lowvolume of production, rich nutrient elements and big price differences among productswith different brands. But, the existed seafood traceability systems have too manyfunctions, complex business logic and some other problems to be solved. Therefore, itis necessary to study on the costly seafood traceability system.In this paper, an indirect sorting method is proposed to implement informationsorting, product tracing and product anti-counterfeiting. To be specific, this paper adoptsa kind of anti-counterfeiting technologies that doesn’t directly store encryptedinformation in the system, but store private keys and dedicated number instead, andDES algorithm is used to encrypt product information. In this way, there will be lessdata stored in the system, and the safety of data also will be improved.This paper firstly analyzes dataflow, use cases and system function systematically,and describes the function modules such as enterprise information management, productinformation management and marketing information management in detail. And then,an overall solution is proposed, including software architecture design, functionimplementation and data flow analysis of the system. The core functions of the systemare generation and identification of anti-counterfeiting codes. To summarize, theimplementation process is encoding the product information, encrypting the encodedinformation to get anti-counterfeiting codes and sticking it on the product tag. Whenproduct information, enterprise information, logistics information and marketinginformation need to be sorted, the anti-counterfeiting code on the tag is entered to beused to get corresponding information. The way in this paper can prevent anti-counterfeiting code from being stolen, protect information in the system from disclosureand reduce the amount of data in the system compared to previous systems.This system is programmed with C#language, B/S software architecture and.NETplatform. System database adopts SQL Server2008. Test run of the system shows thatevery module operates normally, which means that the system meets the demand ofrequirement analysis and design.
