  4. A RFID-based Material Tracking Information System • Overview • Method • Implementation • Conclusion

  5. A RFID-based Material../Overview • RFID reader and back-end database bot -h help to automatically record and store the circulation history and cur -rent status of a tracked object, and they cooperate to synchronize the inf -ormationflow and material flow. Continue

  6. A RFID-based Material../Overview • RFID is a non-contact technology that identifies objects attached with tags. • RFID can also identify mobile objects of high speed. • RFID is thought to be highly automati -c.

  7. A RFID-based Material../Method • We built up a distributed client/serv -erarchitecture which can be used by the administration department of the product plan, the raw material worksh -op, the warehouse management departm -ent, and the semifinished product workshop and other department related with material or product circulation. Continue

  8. A RFID-based Material../Method Continue

  9. A RFID-based Material../Method • Six Main Subsystems Of MTIS Raw Material Subsystem Warehouse Monitoring Subsystem Temporary Warehouse Subsystem Semifinished Product Subsystem Material Tracking Subsystem System Administration Subsystem Continue

  10. A RFID-based Material../Method

  11. A RFID-based Mater../Implementation • Implementation Of MTIS Communication Between Application And RFID Readers Synchronization Of Information Flow And Material Flow Intelligent RFID Guided Vehicle in the Warehouse Material Tracking Continue

  12. A RFID-based Mater../Implementation • Communication Between Application And RFID Readers RFID readers of 13.56MHz is the most suitable one. Continue

  13. A RFID-based Mater../Implementation • Communication Between Application And RFID Readers We Use Two Methods To Communicate With The Readers Application Software RFID Middleware Sever Continue

  14. A RFID-based Mater../Implementation Continue

  15. A RFID-based Mater../Implementation Continue

  16. A RFID-based Mater../Implementation • Synchronization Of Information Flow And Material Flow Modern logistic management requires that the material flow should be recorded in the information system so as to be synchronously fused with the information flow. Continue

  17. A RFID-based Mater../Implementation • Synchronization Of Information Flow And Material Flow Continue

  18. A RFID-based Mater../Implementation • Intelligent RFID Guided Vehicle In The Warehouse Continue

  19. A RFID-based Mater../Implementation • Material Tracking One is that the MTIS will give an ale -rtmessage when the packages of diff -erentclasses or batches are mixed or placed together going through the RFID readers’reading zone. Continue

  20. A RFID-based Mater../Implementation • Material Tracking The other is that client web browser can trace the circulation record and current status of objects and tags in verbal and graphic user interface. Continue

  21. A RFID-based Material../Conclusion • It can be used in most manufacturing and circulation enterprises.

  22. A Distributed ePedigreeArchitecture • Overview • Background • System Componets • Architecture • Protocols • Conclusion

  23. A Distributed ePedigree../Overview • Current ePedigree creation and discov -eryservices rely on a centralized framework, i.e., EPCglobal network. • The centralized system has several restrictions to prevent it from being widely adopted. Continue

  24. A Distributed ePedigree../Overview • An ePedigree is the historical record -s of a product distributed along the distribution system in the supply cha -in from its manufacture to the final customer. • It brings visibility of assets, reduc -tionininventories, just-in-time inv -entoryhandling, reduction in labor, and many other benefits. Continue

  25. A Distributed ePedigree../Overview • Topics Of Interest Single Point Of Failure Unable To Handle A Large Number Of Services Required Transfer Of Different Supply Chain Privacy Issues Continue

  26. A Distributed ePedigree../Overview • Recommended Rolution A Distributed EPC Information Service (EPC-IS) Architecture • Connotation Structure Distributed Hash Table (DHT) ePedigree Certificate Services ePedigree creation Parties EPC-IS Service Providers Continue

  27. A Distributed ePedigree../Overview • Our research goal is to construct a reliable and secure ePedigreecreatio -n and discovery infrastructure.

  28. A Distributed ePedigre../Background • In centralized approach, when a query is submitted to EPCGlobal network, it is directed to root ONS, which return -s the address of EPCIS server containing the requested information. • The major drawback of the existing ePedigree discovery and verification service is its centralized infrastru -cture. Continue

  29. A Distributed ePedigre../Background • Three Restrictions： Single Point Of Failure Complicated Registration And Processing Procedures Privacy Issues Continue

  30. A Distributed ePedigre../Background • A distributed peer-to-peer network infrastructure is a promising candidate. Continue

  31. A Distributed ePedigre../Background • ePedigree makes use of RFID tags for identification of products. • There exist various types of tag formats. • They fall under two basic categories. • General, EAN.UCC System and DoD identity type. Continue

  32. A Distributed ePedigre../Background • So we provide a mechanism by which, the information in the tag can only be read and modified by authenticated participant. • This is attained by encrypting information in user bank of the tag. Continue

  33. A Distributed ePedigre../Background • As we plan to make ePedigreearchitec -turedistributed, we use concept of distributed DNS as basis of our proto -col. Continue

  34. A Distributed e../System Componets • EPC-IS Infrastructure Object Name Service (ONS) Based On Distributed Hash Table (DHT) EPC-IS Databases RFID Encryption And Decryption And Certificate Authorities Continue

  35. A Distributed e../System Componets • Object Name Services Using DHT • Several Difficulties Single Point Failure And Is Not Scalable To Handle Massive Requests Involves Heavy Load Of Administrati -ve Overhead Continue

  36. A Distributed e../System Componets • Several Difficulties： Create ePedigreeHave Little Contro -l On The ePedigreeDiscovery Service Continue

  37. A Distributed e../System Componets • EPC-IS Databases The EPC-IS is maintained by each part -ici pant in EPCGlobalnetwork and it contains information mapping betwe -en a National Drug Code (NDC) and corresponding electronic product code (EPC). Continue

  38. A Distributed e../System Componets • RFID Tag Encryption And Decryption ePedigreeuses tag for identification and storing information about the product. Continue

  39. A Distributed e../System Componets • Certificate Authorities A certificate authority (CA) provides authentication services.

  40. A Distributed ePedig../Architecture • Our distributed ePedigreearchitectur -e is divided into various components : ePedigree work flow, creating distr -ibutedONS using DHT, ePedigreedisc -overy, and verification service. Continue

  41. A Distributed ePedig../Architecture • ePedigree Work Flow Creation of ePedigree is a step by step procedure. Continue

  42. A Distributed ePedig../Architecture Continue

  43. A Distributed ePedig../Architecture • Creating Distributed ONS Using DHT We create distributed ONS in our approach to replace the existing centralized ONS. • ePedigreeDiscovery And Verification Service Discovery and verification service is an integral part of ePedigree. Continue

  44. A Distributed ePedig../Protocols • Three Phases: Creation Protocol For Distributed ONS Deals With Creation Protocol For ePedigree Discovery And Verification Procedures

  45. A Distributed ePedig../Conclusion • In this paper, we propose a distribut -edEPC Information Service (EPC-IS) to make the ePedigree creation and discovery more robust, scaleable, and secure. Continue

  46. A Distributed ePedig../Conclusion • Three-Fold Benefits For Existing Healthcare Industry: It Relieves The Single Point Failure Due To The Centralized EPCglobal Network Infrastructure It Reduce The Processing And Storage Overhead Due To Distributed Processing And Storage Architecture Continue
