  1. 1. RFID Code Resolution Service Based on RFID Public Services Infrastructure Liu Wei Electronics and Information Eng. Department Huazhong University of Science and Technology
  2. 2. 2 Agenda  RFID Code Resolution Service  Introduction  Background  Code Resolution Service Solution  Components  Architecture  Key Technique  Data  Data and Network
  3. 3. 3 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
  4. 4. 4 Where is the Code Resolution Service?
  5. 5. 5 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
  6. 6. 6 Agenda  What is the RFID Code Resolution Service?  Introduction  Background  Code Resolution Service Solution  Components  Architecture  Key Technique  Data  Data and Network
  7. 7. 7 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
  8. 8. 8 Components Distributed Code Resolution System Distributed Mapping Database Network Management System Security and Privacy Protection Framework RFID Code Resolution Service Interfaces for EPCIS, Application Service, Middleware
  9. 9. 9 Architecture Root Higher-level authorized Server Lower-level authorized Server  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

  13. 13. 13 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
  14. 14. 14 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  …
  15. 15. 15 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

  17. 17. 17 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.
