The Design And Implementation Of System Based On Once A Certification Mechanism

As our economy is rentlessly booming, the consume bar has been raised. In such a huge market, tons of fake products are made by the tempting profit. As a result, a great loss is brought to our consumer and legitimate companies. In order to curb fake products, lots of teconologies has been used such as fluorescent security, printing film anti-counterfeiting, telephone security, etc. but these methods are not very effective as faking teconologies developes. In this case, we badly need a new technology to solve this problem, using RFID technology to identify products has become the cutting-edge way to solve this problem. But now, the RFID tag identification method is not perfect which can be easily break by copying the tag. In this paper, to solve this problem, it comes up with a new anti-conterfeiting system and implementes it, which is based on Once-a-Certification mechanism.This paper mainly explores thoese three aspects:(1)According to the vulnerability that tags can be easily copyed due to the fact that the data containded in the tag memory is unchanged, we come up with the idea Once-a-Certification idea which is different from others by changing the data in the tag each time when the tag is validated through the system.(2)Then we analyze the system requirement and design the whole system framework. Based on the overall framework, we divide the system into four major parts as publisher module, mobile module, validator module, client module, and detailed requirements are made in every module. After that, special fault-tolerant controls are designed(3) According to the design requirements of each module, we implement the system in code. Among all, the server program is based on the C # language, client APP is developed by using Android, communication protocol of client is based on Android Volley framework, that of server is base on Web API framework. Both are Http-based communication protocol. The system is completed after RFID tag join. When finished the system, we start to test it by using black-box test method, unit test method and a case that only one of two same tag can be test true. Thus, soliding the Once-a-Certification idea is effective to prevent huge scale of duplicating tag.Firstly, this paper gives a brief introduction about the status of anti-conterfeiting field. Then it brings out the uniqueness of this system and introduces the knowledges involued in. After that, it analyzes the requirement of the system, chooses the proper framework and programming languinge and designs the the whole system framework. According to the design, it talks about the implement methods in detail. At last, several test case is done to verify the validness of the system and a summary is presented.
