2 ucommerce Sub-type of ecommerce / mcommerce (Watson et al. 2002): The use of ubiquitous networks to support personalized and uninterrupted communications and transactions between an organization and its various stakeholders to provide a level of value over, above, and beyond traditional commerce. It is characterised by: Ubiquity: being available everywhere: Universality: being able to interoperate (everywhere) in heterogeneous environments Uniqueness: relating services to a context such as the location Unison: allowing multiple parties to work together 1 of the 10 key factors for success of mobile services & m-commerce For location awareness (Uniqueness) according to [Marcussen ]. 3 Outline Motivation & background Agent-based tourism infrastructure Scenarios and privacy requirements Privacy System design and evaluation Conclusion 4 Page 2

3 Why use agents to underpin U-Commerce? Distributed Service Challenges Scalability, availability, security, etc. Information Overload Task complexity Overload Heterogeneity: structure & Operations Dynamicity: open, JIT markets Additional U-Commerce challenges Ubiquitous: everywhere Unique: personalised Universal: common understanding Unison: acting together Agent Model Robust distributed system infrastructure + distributed, autonomous, agents Share info, Smarter filtering Share tasks, delegate rather instruct Mediation Adaptation, awareness of others U-Commerce Model Ubiquitous agents Personal Assistants Share semantics Collaborative agents 5 About the IC lab@elec.qmul.ac.uk Intelligent Communication (IC) Lab, department of electronic engineering, Queen Mary (college) 5 Academic staff & ~ 20 PhD students Related ICLAB Projects ADAMANT: Airport Decision And MANagement Network intelligent passenger support J2ME, personalisation, position via WLAN trilateration, prioritised QoS. Trial: Athens Olympics CRUMPET: tourism location aware services Micro/FIPA-OS, personalisation, position via GPS & GSM, content adaptation to network QoS, terminal, thin & Fat client-server, 2 user trials USHER: Ubiquitous System Here for Roamers (CRUMPET mk2) JADE, personalisation, position via GPS, Privacy Model Antennas Lab Body centric antennas and UWB to support wearable computing & communication 6 Page 3

4 CRUMPET Project CReation of User-friendly Mobile services PErsonalised for Tourism CRUMPET was an EU IST 5th framework project Location-aware Multi-Agent -agent technology Services Location -aware services It has 2 main objectives 1. Implement & trial context-aware tourism related services for nomadic users Adapts info. to 4 contexts: location, person, QoS & Terminal 2. Evaluate agent technology as a suitable approach for these Multimedia information access over mobile terminals Personalised user interaction 7 Design issues Smartness of client (fat) vs. infrastructure (thin client) Performance in a lean resource environment Usability Maintenance Make agents easier to manage How to ease the introduction of new content & services Management Privacy Security 8 Page 4

5 Thin client, 3 tier Architecture This deployment architecture has a smaller client-side footprint and is suitable for deploying in lower end PDAs & suitably equipped mobile 'phones 9 10 Page 5
