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

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

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
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
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 (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.
