| The Application of RFID technology in logistic field makes huge amount of EPC information travel along with the goods on the supply chain. EPC Network technology provides a platform for information storage and exchange, so that the huge amount of information carried by RFID tags not only can be recorded, but can be shared. Wealth of information stored in the EPC Network makes it more and more focus on the EPC network application systems. However, EPC network technology is still in the initial stage of research; How to explore the practical value of the EPC information and how to choose the appropriate information for application system and in other aspects still has some difficulties. In addition, because the EPC network technology is still immature and lack of actual operation platform, the research of EPC network's specific applications becomes an urgent problem.This thesis will keep the research of product anti-counterfeiting system based on the EPC Network as the main line, integrate RFID application technology, EPC Network technology, product anti-counterfeiting technology, combined with the features of EPC Network technology and the requirements of product anti-counterfeiting and design a whole solution for product anti-counterfeiting based on EPC Network: according to the principle of supply chain anti-counterfeiting, pre-build product supply chain anti-counterfeiting model corresponds with the product in the system and define the rules of the product, who must obey the rules while travelling between the nodes of supply chain according to the model; when users launch query with EPC, the system initiates inquiries to EPC network, and access to the information recorded when the product travels between the nodes of supply chain; at the same time, the system get the anti-counterfeiting model according to the EPC and analyze the query results of EPC Network to judge the authenticity of the product. If the results have high similarity of the model and its rules, then identify it as the real thing; otherwise identify it as changing products or counterfeit products. Through this solution the current anti-counterfeiting technologies can be improved effectively and make full use of information on all supply chain nodes to product anti-counterfeiting.This thesis first describes the present research situation and the background of this research, and then raises the research content and innovation of the thesis. Secondly, the thesis introduces the mainstream of the research of EPC network, EPC network service systems and current anti-counterfeiting technologies, discussing advantages and disadvantages of these anti-counterfeiting technologies. After all of this, the main purpose of the thesis is raised and all technologies related are introduced. Then the product anti-counterfeiting system based on the EPC network researched in this thesis is given, and the basic principles - supply chain anti-counterfeiting, as well as the anti-counterfeiting model in systems which are derived from the study of supply chain anti-counterfeiting are described in depth, including basic model, its improvements and the anti-counterfeiting rules based on the model. Further study and extension are made on the anti-counterfeiting model and its anti-counterfeiting rules. Then the system on the whole scope and the concrete realization of all main modules will be described. Test cases are designed and apply to the system to test and verify the basic principles and system. Finally, it gives a summary to the thesis, and raised some further research point of the product anti-counterfeiting system based on the EPC network. |
