RFID Lab, Dept. IECS, FCU 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 4

RFID Lab, Dept. IECS, FCU Good Recycle Business Model 5

RFID Lab, Dept. IECS, FCU 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 6

RFID Lab, Dept. IECS, FCU 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 7

RFID Lab, Dept. IECS, FCU 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 8

RFID Lab, Dept. IECS, FCU The Object-Oriented Middleware 9

RFID Lab, Dept. IECS, FCU 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. 10

RFID Lab, Dept. IECS, FCU 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. 11

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

RFID Lab, Dept. IECS, FCU 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 13

RFID Lab, Dept. IECS, FCU 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 14

RFID Lab, Dept. IECS, FCU 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 23

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

RFID Lab, Dept. IECS, FCU 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 25
