PRESENTATION AGENDA

Background — The Smart Spaces Paradigm

M3 Spaces

— Information Processing

— Security

Conclusion / Discussion

Design Challenges — Interoperability

THE SMART SPACES PARADIGMFollows the Ubiquitous Computing Vision

: Smart objects are executed on a variety of digital devices and services are constructed as interaction of agents in information sharing environment — smart place

THE SMART SPACES PARADIGMCan we utilize the infrastructure to the fullest?

— existing Internet service infrastructure is still not efficiently utilized

— what happens with the addition of IoT?

low communication between services results in high fragmentation of

information

THE SMART SPACES PARADIGM

Huge opportunity in …

— the analysis of all information

— the efficient use of all information

— by all applications

connect new devices flexibly to the space and consume information from any of the services

THE M3 CONCEPTMulti-device, Multi-domain, Multi-vendor

is the next step of “smart spaces”

Comparable to the Semantic Web

Giant Global Graph

THE M3 CONCEPTMulti-device, Multi-domain, Multi-vendor

is the next step of “smart spaces”

Comparable to the existing Semantic Web

Giant Global GraphM3— local

— dynamic

— highly heterogeneous

IoT becomes a feasible internet-working substrate on top of M3 spaces

DESIGN CHALLENGES

Inter-operability : how to manipulate with information in an open, dynamic, multi-device environment

Information Processing : how to reason over the information and to construct the services

Security and Privacy : how to provide integrity and confidentiality of processed data and communication

M3 SPACES

Key Goal : seamless provision of users with information using the best available resources for all kinds of devices that the users can use in the ecosystem

The Focus : dynamic mash-up and integration of many users, devices, applications

M3 Domains : span from embedded digital equipment and consumer electronics to the Web

M3 SPACES

Knowledge Processors (KPs) : independent agents that provide space-based communication and synchronization

Semantic Information Brokers (SIBs) : maintain a knowledge base — habitual data, relations, information as computations

M3 SPACES

Room is equipped with sensor devices that sense the physical parameters of the environment and participant activity

Example : Smart Room

All knowledge is collected, organized, shared, and searched in a common smart space

M3 SPACESExample : Smart Room

Examples of Particular Problems — Integration of joining devices is seamless >> a new device is available

— Service management is adaptive >> what happens when parts are unavailable — Knowledge exchange is supported >> changing screens based on user discussions

INTER-OPERABILITY

Current Status — current IoT standards have been created for single domains.

>> we need to move away from domain-specific standards — a “KPI”

Information available on some devices may be interesting to other devices

(Some) Devices should communicate with the external world

INTER-OPERABILITY

Device Inter-operability : covers technologies for devices to discover and network with each other

Service Inter-operability : covers technologies for space participants to discover services and use them

Information Inter-operability : covers technologies and processes for making information available without the need to know interfacing methods of the entity

INFORMATION PROCESSING”Reasoning Capabilities”

KP Data Connectors KP-Capable Devices

SECURITY & PRIVACY

The Dilemma : Finding the balance between “shared information” and “privacy”

Back to the Smart Room Example

SECURITY & PRIVACY

Share Level Security : which locally available knowledge is published in the space for sharing?>> each KP makes own decisions

Space Access Control : span from embedded digital equipment and consumer electronics to the Web >> an access function limits other KPs to the shared content pool

Communication : Meta-information and knowledge of “who’s the owner”

SECURITY & PRIVACY

Share Level Security : which locally available knowledge is published in the space for sharing?>> each KP makes own decisions

Space Access Control : span from embedded digital equipment and consumer electronics to the Web >> an access function limits other KPs to the shared content pool

Communication : Meta-information and knowledge of “who’s the owner”
