Prepare for Global Environmental/Health
Concerns

ITU ICT & Climate Change Symposium
June 18, 2008
Motivations and Objectives（１）
• Climate change and/or pandemic are global
life threatening environmental/health
concerns.
– Not only our lives but also future generation
lives
• There will be many different
technical/medical solutions.
• To verify the effectiveness of technologies
and solutions for reducing those concerns is
important.
– Effective solutions should be promoted and
expanded.
• ICT can play an important role to verify the
effectiveness of technologies and solutions.
• A region(/area) could adopt different
technologies and solutions.
Motivations and Objectives（２）
• To identify and separate problem areas from other
healthy areas is required.
– A problem area: The
not be effective in
– A healthy area: The
be effective in the
adopted technologies and solutions may
the area.
adopted technologies and solutions may
area.
• Monitored data are timely collected via network and
analyzed by experts.
– A large number of monitoring devices are required.
• A network system based on device ID that would
deliver the device information and its monitored data
and attributes to scientists, decision makers and
users who can make a good use of the data.
• An international institute to coordinate
those activities and analyses, and to promote

Standardization requirements of such ID

• standardized interfaces between ID
network and devices (physical and
logical layers)
• standardized procedure to identify,
verify and exchange device ID,
attributions and collected data, and
• standardized process to maintain
accuracy of collected data.

The terminal/end user equipment accesses to the public network via
the User Network Interface UNI (10).
Then, it contacts a necessary service via the reference point (11).
The service will provide additional information back to the termina
user.

General IdM Architectural Model
•
•
•
Entity - a User or a
Requestor, who seeks Service
from a Relying Party, and
provides a claimed Identity
to that Party.
Relying Party (RP) - Needs
to have this Identity
authenticated before
providing the Service.
Queries Entity for the name
of the Identity Provider for
the claimed Identity.
Queries Identity Provider
for validation of the
claimed Identity (and for
the attributes of that
Identity).
Identity Provider (IdP) Authenticates the claimed
Identity, and may return
attributes of the Identity
to the RP. Uses trust
