Study And Implementation Of Wireless Anti-counterfeiting System Based On GPRS

It's a very important problem to beat counterfeit and protect consumers' benefit. But most of conventional anti-counterfeiting techniques can't work well. Because of it, counterfeit is very ubiquitous. So the scientific effective measures must be taken.This thesis analyzes the anti-counterfeiting techniques at present, and puts forward a new-style anti-counterfeiting system based on GPRS network, Internet and encryption technology. This system includes the product ID-iButton chip, GPRS wireless anti-counterfeiting code reader, corporation server and so on. The product ID-iButton chip is embedded in products, on which there is an interface connecting to the code reader. There is an only ID in it. When reading the ID, it should abide 1-Wire communication protocol; The code reader is used for reading the iButton ID, encrypting and decrypting the code, transmiting the data by GPRS wireless network, displaying the information by LCD and so on. The code reader encrypts the ID and transmits it to the corporation server to identify it. At the same time, the code reader is encrypted, and its data can't be read in order to keep the system's security; The information about products is stored in corporation server, waiting for being inquiryed. The corporation server is also encrypted. It can't be logged on if the key is wrong.The primary work of this thesis is about design and realization of GPRS wireless anti-counterfeiting system. It includes the hardware system design of GPRS wireless anti-counterfeiting code reader, which is the hard-core of the system;the software of code reader; writing the embeded TCP/IP protocol;writing the testing software of long-distance server and giving the test result;setting up the wireless anti-counterfeiting test system.At last, the thesis discusses the problem in the system design and giving the resolvents.By research in this thesis, the GPRS wireless anti-counterfeiting test system is successfully designed. And it lays the foundation for the eventual realization of the whole system.
