Design And Implementation Of EPCIS Credible Service Prototype System Based On SOA

The rapid development of the information age, the research and application of things becoming more mature and extensive study of things in which the upper access and query data played a key role. This requires that the underlying electronic hardware such as tags and readers have a good study to obtain the correct data; how to capture these data are correct that things the upper part of the research information system is essential. Things objective is to form a unified global nature of the openness of the network structure, to achieve material properties dialogue, the key question is how to build things within the system and how the system in all things interactive. Things ONS and EPCIS among the various application modules are the most direct interaction among the core components, they are all independent of the physical connection between the hub of networked systems.Things on the authority of the global research organization EPCGlobal promulgated a series of standardized in-depth research and information exchange on the Internet of things need to fully understand, come to study the key technologies in this field capturing EPCIS events and treatment monitoring, event subscription query, event query callback operation, ONS location query, which is the core of the problem EPCIS server-side implementation of the process of how to ensure the safety of ONS query credible, in this based on the service call.In accordance with the relevant regulations, the establishment of a sound EPCIS database, EPCIS server to complete all the base class library development. EPCIS server side implements the interfaces of all services, including EPCIS event monitoring mechanisms, real-time queries and subscriptions, access control, query callback interface and other modules to serve in the form of UDDI server to publish successfully, enabling the client to facilitate the call Corresponding services. The ONS implemented based on UDDI core algorithm, the experiment is completed based on the ONS DNS simulation of multi-server set up.According to the specification and properties of EPC, designed and built the EPCIS database. SOA-based services, research, design and implementation of service based on UDDI ONS information inquiries.ONS resolution process for the safety and credibility in the enterprise information is the interaction of things important and difficult research, made light PKI-based encryption model for things.In developed various modules of things on the basis of interaction with the bottom and the upper formation, the formation of a complete prototype system of things. Many classes have been packed this system completed, and left a lot of interfaces to easily reuse and used for secondary development.
