As the developing of broadband network, E-government and informationization, the Move Intelligence Service System(MISS) is widely used in various fields. In the practical application people found the security problem of MISS is very important. In consideration of the fact that Asian Games will be held in Guangzhou in 2010, and Guangzhou existing hotel service doesn’t have unified service system, this paper designed and developed a MISS encrypt/decrypt based on NDIS network link .In this system, we use the Fuzzy Set to express data structure, use the Fuzzy Hierarchy Synthetic Evaluating Model to assess hotel level, finally use the Fuzzy Cluster Analysis method to provide each kind of traveler with di_erent types of hotels . Travelers can easily query and transact hotel businesses by using telephones or other communication facilities. In the practical application, our MISS surpasses the similar products in security.
