Project Data and Starting Points

• EU co-funded project (a 30 months, 4.4 M€, project) – www.ist-sms.org

• Mobile services have not matched the growth of the Web– Cost (of data access)– Complexity (in use and deployment)

• Vicious cycle:– high cost & few services -> few users

– few users -> no incentive to offer services

• However,– Cost of broadband data access is decreasing (e.g. flat rate 20€ x

month, max 500 MB; or 30€x month, max 1.5 GB; or 9€ per month for selected applications)

Technical Motivation

• Success of the Web (among other factors)– Easy to use– Easy to create

• Mobile services– Unknown to users– Difficult to use– Not trusted – Difficult to design and deploy (especially for “small” service

providers, e.g. SMEs, local government departments, NGOs, individuals)


Design goals for SMS

• Mobile services have to be:

– Simple to find

– Simple to use

– Simple to trust

– Simple to develop

Main achievements

• Idea of MEMs– notes with info about a location, a person, a service, or a Web site

• The MOVE client– an open source client software allowing SMS users to access services

without passing through a conventional web browser

• Tools for developers (e.g. Authoring Wizard)• SMILE

– middleware for communication providing support for large distributed applications involving multiple heterogeneous devices

• SIM-based Security and Privacy– Exploitation of the security provided by the SIM card

• Design, production, and delivery of real SIMs• Real life trials


MEM: the problem…

• Imagine a tourist travelling through Seoul ( 서울특별시 )• Sometimes he needs information – for instance on how to

reach a particular destination. Sometimes he needs to perform an action – like buying a theatre ticket

• It’s a very different scenario w.r.t. “googling” from a fixed PC• Eight seconds rule…


MEM: the problem…

• Well-designed mobile services may serve these needs but…

• If he sees the time of a show on a poster, all he can do is try and remember it, or write it down on a piece of paper, or perhaps on its mobile device

• If he wants to tell a friend to come and meet him at a certain café he has to ask the owner for the address (or read the address in Korean) and try to explain by phone to his friend how to get there


MEM: the problem…

• Missing pieces:

– Capturing information from the environment. It should be easy for users to capture and reuse information from the environment and from other services using mobile devices

– Likewise, sharing (complex) information from the mobile device with other users and servers should be simple as well


MEM: the idea

• MEMs are electronic notes containing a set of attributes associated with a specific class of information (e.g. information describing a location, a person, a service, or a Web site)

• Users can capture MEMs from the environment or from other services, store them for future use, share them with other users and send them as input to other services and applications

• MEMs can be created both on the mobile terminal and on a server– We developed a web application which lets the user create and

display the MEMs and send them to mobile phones, but MEMs can also be automatically created (e.g. Restaurant MEMs from existing databases of restaurant information)


MEM: the idea

• A MEM is used to handle information about places (like shops, restaurants, buildings, monuments), people, services, events

• Examples• Guide patients to blood test room of a given hospital (MEM created

by patient’s family doctor)

• Guide students parents to the University’s aula magna for the graduation ceremony (MEM created by students or by the University administration)

• Guide perspective buyers/clients to a shop/restaurant/hotel (MEM created by shop/restaurant/hotel managers, available on a web page and/or again sent via SMS)

• Guide a friend to a meeting place, to one’s country house, to …

• Guide a group of people to a common event (five-a-side match?)


Usage scenarios for MEMs

• Leaving for Seoul– Mobile booking of a flight (send a digitally signed MEM, receive a

MEM with flight info)– Few days later, at the airport. Using the MEM data, the airport

provides the user with a “Take me to check in” service– Before leaving the user sends a MEM to a friend who will be picking

him up on arrival. The friend will use the MEM to check for any delay in the flight.

Sending and sharing MEMs

• A key feature of MEMs is that they are easy to share and send to other users

• Where users have installed the MOVE client application they can send MEMs to their friends (e.g. a MEM with the time and place for an upcoming meeting)

• Alternatively they can embed the URL for the MEM in an email, IM or email message

• MEMs intended for use within a specific community or for users at large can be published to “MEM servers” which make them available to end-users in the relevant context


MOVE (Mobile Open and Very Easy)

– MOVE is a sort of browser for mobile services; it is an open source, stand-alone J2ME (CLDC) application. It runs on a large set of terminals (both Symbian and Windows Mobile)

– MOVE provides the capability to search for services and present the most suitable services according to users’ preferences and current context


MOVE screenshots

• User Interface Evolution (XUI)


Some features of MOVE

• Creating, showing and sharing “MEMs”• “Push” and “pull” based access to services • Outdoor localization/navigation

(GPS receiver + mashup of web based maps)• Indoor localization/navigation

(may interact with indoor navigation systems)• Information services (Weather, travel, traffic, shops…)• “Physical mobile interaction” (e.g. recognition of visual

tags)• Interaction with the SIM using the SIM web server approach


SIM-based Security and Privacy

• Secure management of personal user data– User Identity (Multi-Identities), Personal data– Public/Private keys, Digital Certificates

• Portability of personal profile data and identity

• Signing / Signature verification for MEMs and Mails

• Service trust verification – Service identification– Trust level management for

known services– Support of Trust level evaluation

during service discovery

• User Authentication

• Secure Payment / Micro-Payment


Implementation Status for the Trial

• Three SIM Card Applications defined, implemented and tested:– User Data Management

- Secure Storage on SIM– Digital Signature Service

- Building Signature with SIM identity– Software Deployment Service

- IMEI Tracking by SIM

• Factory Production of 100 Test SIM Cards including Telecom Italia Subscription Data

• Gateway Software for Windows Mobile Phones• Internet Server for Short Message Gateway

Trial 2 – University of Rome Tor Vergata


Trial 1 – Athens Airport

• Athens International Airport provided:– A fully operational environment (Wi-Fi,

Bluetooth)– Support to users, and actors by IT&T

engineers on a daily basis– The Users of the trials– Hosting and support of the integrated

SMS platform within the airports’ infrastructure

• Services– Flight Information (MEM)– Retail Information

• (created with the Authoring Wizard)


Trial 2 – University of Rome Tor Vergata

– Outdoor localization and navigation (with searches and save into MEMs)

– Find my friends– Creating MEMs and sending MEMs from the mobile phone– Creating MEMs on the PC (MEM server)– A chat application– A “location tracker” application (records a log of a track into a MEM)– Poll applications– News application– SIM based services: save passwords into SIM, signing and verifying

messages, assisted download of MOVE– Indoor map of campus


Business scenarios

• Vertical applications

• Single SMS provider / “walled garden” approach

• Open / multi-provider approach


Vertical application

• Examples:– a gaming application offered by a web portal– a social networking application (e.g. soundtribes)– an application to find people/places at a conference center– an application to manage agendas of travelling workforce– a tour guide application

• A different stand-alone application on the phone for each example (installing an application is very easy, for example by sending a Bluetooth message!)

• Server side facilities are not linked• Each server side will handle its own “subscribers”


Single SMS provider / “walled garden” approach

• Examples:– a set of services offered by one organization

• The client is an application on the phone customized by an SMS framework service provider

• Services are offered through the mediation of the SMS framework service providers


Open / multi-provider approach

• There is a single application on the phone (the MOVE client) that can connect to different SMS framework service providers and to any service

• Services can be offered through the mediation of the SMS framework service providers

• Services can be offered without any mediation

• Users can be linked to a “default” or “home” provider that can offer services (e.g. assists the user in search/customization)
