mTag - Architecture for Discovering Location Specific Mobile Web Services Using RFID and Its Evaluation with Two Case Studies

This paper introduces mTag, a distributed event-driven architecture for discovering location specific mobile web services. Service discovery is initiated by touching a fixed RFID reader with a mobile passive RFID tag attached e.g. to a phone, which results in information of available services being pushed to user’s preferred device. We present a deployment proposal and prototype implementation, which is evaluated in form of two case studies in the true environment of use. The case studies show that mTag provides a promising approach for service discovery with mobile devices. 1

Passive Indoor Positioning System (PIPS) Using Near Field Communication (NFC) Technology

Travel can be an enjoyable experience but it can also be stressful when one is unable to get to the destination in timely manner. Satellite navigation systems (satnav) such as the ubiquitous Global Positioning System (GPS) provide an aid to locating unfamiliar places without hassle. However, the effectiveness of satnav stops at the doorstep of the building due to its requirement for line of sight with orbiting satellites. Within a large complex building, navigation typically relies on building signage, information from kiosks and getting assistance from information desks. The advancement of mobile devices and wireless technology offer an interesting proposition for the development of indoor positioning systems. In this paper, we propose a passive indoor positioning system to provide navigational aid and discuss findings from our pilot experiment using NFC technology

Authorising m-commerce with location

Global fraud in 'cardholder not present' transactions over the World Wide Web continues to grow, in line with the ever-increasing numbers of transactions carried out over this medium. Unfortunately, at present the measures designed to combat against this fraud continue to require improvements to be made to limit the fraud. In this paper we will propose a series of indicators that financial service providers should consider in their attempts to limit fraudulent transactions. The indicators make use of prevalent technologies coupled with a need to place more power to limit fraud in the hands of the customer, especially given banks are continually moving responsibility onto the customer to protect their data.Whilst the banking sector uses a variety of measures for fraud detection at present there is only limited usage of device related indicators that customers could establish to limit the fraud on their account. For instance, whilst many users will have multiple devices the likelihood of a user performing a valued transaction on a device outside of that subset of devices is limited. Therefore, an indicator linked to device usage controlled by the customer may help to introduce further difficulties for the individual attempting to commit fraud. Similar indicators exist linked to device geo-location, service usage, time determinants and other aspects.This thesis demonstrates that users do not find device location services too complex to use. Indeed, providing user controls to enabled personalised security settings increase users trust levels. This research proposes security controls are embedded within users banking application. The effect of this approach increases users willingness to engage with location based security controls. Any initial privacy concerns are overcome as long as the proposed controls remain within the banking application
