2. Outline • Internet of Things architecture for a RFID-based product tracking business model • SHARDIS: A Privacy-Enhanced Discovery Service for RFID-Based Product Information • A Temporal-based Model of Uncertain RFID Data

3. Internet of Things architecture for a RFID-based product tracking business model F´elix Jes´us Villanueva, David Villa, Francisco Moya, Maria Jos´e Santofimia, Juan Carlos L´opez 2012 Sixth International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing

4. Introduction • Goods traceability is a growing application • This paper therefore proposes an evolution of goods trace applications, mainly motivated by the wish of obtaining a global ecosystem • This work proposes the use of Object-Oriented Distributed Middlewares • The information written in RFID tags is used for invoking remote methods in objects

5. Good Recycle Business Model

6. Good Recycle Business Model • User needs to install RFID readers at home and provide profile information • IoT business model: • Incremental • Fault tolerant • Scalability • Architecture reuse • The main drawback: Sensible information

7. The Object-Oriented Middleware • Traditional object-oriented middleware • A specification of the interfaces of all services • Implementation • Server • Proposed platform • Identity of manufacturer within the product code in the RFID label • Interpret RFID identity and invoke the method

8. The Object-Oriented Middleware • Architectural structure • Each entity has several input points and output points • Each entity also has a profile resolver in which other parties can get information related to the entity • A public key infrastructure protects the information • Inter-Domain Messaging(IDM) architecture • IDM overlay architecture • IDM imposes a global hierarchical addressing scheme for objects • Any client is able to invoke any other remote party in the system • The required information: Object identifier, Product code, Owner • The readers can communicate to remote objects through an a embedded IDM router

9. The Object-Oriented Middleware

10. The Object-Oriented Middleware • Identifiers • Manufacturer service identifier: It is an IDM address • Product kind identifier: A unique product number • Serial number: A unique serial number • Product tracking protocol proposal • An event service: get product tracking • A query service: get information from other parties.

11. Conclusion • This paper proposes an architecture for massive RFID product tracking • The author of this article strongly believe that only by involving user, companies will be involved in IoT ecosystems. • In the proposed business model a novel global tracking system for products is proposed, in which users could obtain benefits from recycle activities.

12. SHARDIS: A Privacy-Enhanced Discovery Service for RFID-Based Product Information Benjamin Fabian, Tatiana Ermakova, and Cristian Müller IEEE TRANSACTIONS ON INDUSTRIAL INFORMATICS, VOL. 8, NO. 3, AUGUST 2012

13. Introduction • The standardization of a global numbering scheme for physical objects, the Electronic Product Code (EPC) that is stored on RFID tags • EPCglobal Network (EPCN) • Discovery Services (DS) for the EPCN • No official standard has been finalized • No sufficient mechanisms to address the privacy requirements

14. Introduction (cont’d) • SHARDIS • SHARDIS will be deployed as an infrastructure peer-to-peer (P2P) network • We provide end-to-end document authenticity and data origin authentication by digital signatures • SHARDIS as a cooperative industrial infrastructure network will in practice be based on cryptographically secured node identifiers • SHARDIS address document

22. Reconstructing Multiple Documents

23. Conclusion • This paper presented SHARDIS, a P2P-based discovery service architecture for the EPCglobal Network that enhances client privacy by applying secret-sharing on the information documents of interest • Without needing key predistribution, making it suitable for flexible, open, and global application scenarios of RFID and the EPC framework

24. A Temporal-based Model of Uncertain RFID Data Dong Xie, Sheng Q.Z., Jiangang Ma 2012 Sixth International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing

25. Introduction • A storing RFID data model employs a triplet (EPC, reader-id, timestamp), which is not very effective • Insufficient data • Incomplete data • Massive data • We propose a temporal-based data model of uncertain RFID data to capture uncertain RFID data and support complex queries

26. Temporal-Based Data Model OWNER

27. Querying Uncertain RFID Data • Tracking • Tracing

28. Conclusion • This paper has identified several features of uncertain RFID data, and proposed a temporal-based data model for managing uncertain RFID data

29. My Comment

30. My Comment • Third paper can use EPCglobal framework.
