Two-dimensional code security image and its application in design of food traceability system

Abstract

Two-dimensional code technology has been applied to all aspects of production and life, such as auto parts production line tracking, product traceability, medical emergencies, e-commerce, media and tourism. However, these two-dimensional code application generally concentrated in record numbers, letters and words, but in practice many applications need to record the image, such as the admission of students who require a printed picture as a security basis. Establish an efficient food traceability systems available, one aspect of the need to analyze the food production and processing sectors in the more complex and require the use of efficient and reliable two-dimensional code identification and data collection related equipment; on the other hand to analyze the correlation algorithm for large data storage and traceability information model. Introduction In recent years, food safety issues widespread concern in the community and public opinion, it is related to people's health and life safety of the livelihood of people [1]. The sales cycle data collection, storage, make the appropriate inquiries and supervision and management, and provide consumers with accurate, efficient and credible food information platform, the establishment of information traceability system is an ideal tool for effective management of food safety [2]. In the construction of traceability system, involving every aspect of food production, transportation, storage, etc. should be able to be recorded, it can be traced back [3, 4]. Food needs to be monitored by IT to connect through the appropriate bar code reading device and the internet, to achieve effective management of food information [5]. When it comes to research and development in food traceability system, how to integrate business data really a industry chain, establish and improve data collection, transmission, storage, query system model, multi-user, multi-sectoral inquiry, supervision, traceability and other functions, is reform should focus on system design issues need to be developed considering the time [6]. To sum up, really want to establish a food traceability regulatory decision-making platform, making the government decision-making and food control data can be effectively supported and technical support from the platform, forming a food traceability system based on information technology [7]. The study of two-dimensional code image storage and identification has important significance. This paper presents a two-dimensional code technology for product traceability applications logistics system solutions through the use of information technology. Establish and improve the food safety traceability system for food production, circulation can be traced back to do, you can query, manageable, of which the origin of the raw materials for the food information, logistics information. Related theory of Two-dimensional code image Traceability security information management. According to statistics, at present our products in the circulation costs account for 40% to 60% of the total cost, which not only increases the burden on consumers, but also seriously affected the promotion of their products. Production-oriented enterprises through the establishment of the logistics management system, the products in circulation dropped 20 percent less cost. Therefore, the establishment of information security products, logistics 4th National Conference on Electrical, Electronics and Computer Engineering (NCEECE 2015) © 2016.
