Internet of Things architecture for a RFID-based product tracking business

model

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

Good Recycle Business Model

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

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

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

The Object-Oriented Middleware

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.

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.

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

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

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

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
