        • Data and Network
    • What is the RFID Code Resolution Service?
      • RFID Public Service System can correlate Items information in different areas, and achieve reunification of logistic and information flow.
      • RFID Public Service System can be divided into two levels:
        • Dedicated application service (Region, Industry, Enterprise Application)
        • Common base service (Code Resolution)
      • RFID Code Resolution Service is the core of the RFID Public Service System.
        • Provide Code and Address Resolution Service
        • Achieve application service orientation according to the electronic product code
        • Achieve information exchange and share
    • Where is the Code Resolution Service?
    • Background
      • EPC Global – Logistic
        • Things of Internet
        • Including: Tag, Reader, Savant, ONS, EPCIS
      • UID – Everyday Application
        • U-code computing model
        • Including: Ucode, Information Server, Ubiquitous Communications, Ucode Resolution Server

      • Code Resolution Service Solution
        • Components
        • Architecture
        • Key Technique
        • Data
        • Data and Network
      Agenda
    • Service Users
      • RFID Key Data
        • event, index, content
      • User Roles
        • Code Managers:
          • Distribution of the Code
        • Information Owners:
          • Agencies who store RFID events and information, such as single enterprise, leading enterprise in supply chain, industry charging ministry, and etc.
        • Base Service Provider
          • Address Resolution, Active/Passive Information Service
        • Application Service Provider
          • Value Added Service based on RFID Data
        • Query User
    • Components
    • Architecture
      • Is a index service.
      • Is a public resource for all the RFID network users.
      • For the scalability and realization, it should be a distributed architecture.
        • Only one root server
        • Every server node can have one or more child
        • Every server only have one father
    • RFID Code Resolution Process Address Resolution Location Search
    • RFID Code Resolution Process (Continued) CRS: Code Resolution Server O-CRS: Other industry CRS L-CRS: Local CRS
    • Key Technique
      • RFID Code Resolution Network Framework
        • RFID Code Resolution Network Transport Protocols
        • RFID Code Resolution Network Security and Access Control Protocols
      • RFID Root Resolution System
        • RFID Code Register and Management
        • Multi-Codes Resolution
        • Security Protection
      • RFID Distributed Resolution System
        • Data Synchronization and Update
        • Data Distributing and Prepare Strategy
    • RFID Code Resolution Network Framework
      • RFID Code Resolution Network Transport Protocols
        • PDU format
        • PDU Sequence flow
        • Information control method for process and exception
      • RFID Code Resolution Network Security and Access Control Protocols
        • Key
        • Encrypting algorithm
        • Signature
        • Security Architecture
    • RFID Root Resolution System
      • RFID Code Register and Management
        • Enterprise Register and Items Register, Human Register and Automatic Register
        • Data Management, including add, modify and delete
      • Multi-Codes Resolution
        • Can support multi-codes, such as NPC, EPC, UID, and etc.
        • Multi-Codes Control, can add new style RFID code or delete old style RFID code
      • Security Protection
        • Eavesdropping, Holding up RFID information
        • DDos
        • Re-transmission attack
    • RFID Distributed Resolution System
      • Data Synchronization and Update
        • Cache Strategy, cache data updating
        • Address mapping data synchronization, ensure the data on Code Resolution Server is consistent with it on EPCIS
        • Sequence Flow and Data exchange rule
      • Data Distributing and Prepare Strategy
        • Application Service
    • Data
    • Data (Continued)
      • Precondition
        • It is not need for user to know every node of a supply chain.
        • Maybe some MNCs want to manage related supply chain information by theirselves.
        • Different users may get different supply chain information.
      • Solution
        • Allow several nodes of a supply chain to be stored in one server, and this server only can be controlled by some authorized users.
        • Every node of a supply chain may be a small supply chain.
        • General user can retrieve a fragmentary supply chain information, this information may contain manufacture, distributor and retailer.
        • To retrieve more information, you should have right to search in-depth.
    • Resolution Network
