I see things having their own identity (perhaps
provisioned at manufacturing etc), but when the nature of an
interaction or message happens 'on behalf of' a particular
user, then that user's identity must also be captured &
expressed

Dear
All,
I have a quick comment on the Benoit second question about "an
object in fact just carrying or using its owner's identity?". I
suppose objects in the future could be able to do a lot of things
automatically, to react to emergency situation for example. When
things become "smart", their identities then could be something
else rather than "owner's identities", where the concept of
ownership would be quite blur. Moving forward to IoT vision and a
smart world, well, things should have there own identities rather
than rely on their owners.
Thank you.
Best regards,
Son Han

Hello all,
During last teleconference, I have asked a question that has not
been
answered during the call. Ingo suggested to ask to the whole
list.
Short:
Where to put the limit, for a thing or object, between a simple
list of
attributes and a whole/real "identity" for that object? Does the
object
need a minimal computing power to have an identity? Or the
simple fact
to be able to answer a request (even if it is "passive") is
enough for
that? Are there other criteria (like, for an object, just having
a
unique ID)?
Another question: in a lot of cases, instead of a proper
identity,
doesn't an object in fact just carrying or using its owner's
identity?
A bit longer:
Nowadays, a lot of devices, objects and things are able to
communicate,
either actively or passively (upon request, as with RFID). Most
of those
objects have an identifier and often a set of attributes. Some
of them
are able to react to their environment. But in some cases, it
seems to
me that certain object don't have a "digital identity" on their
own. I
think that they just carry a set of complementary attributes for
another
entity, or just have a set of attributes, but not a "real"
identity, or
act on behalf of another entity.
Examples:
- A light-bulb has an address (IPv6?) and some attributes
(e.g.
firstUsed:<a date> and onFor:<a duration>). Is it a
real identity?
- A micro-chip has just an ID number. Isn't that number just
an
attribute of the identity of the pet wearing it under its skin?
- Consider a car. It sometimes act on behalf of its owner or
driver
(when paying a toll), and sometimes for itself (when connected
to the
computer of the garage).
- What is the difference between an economic good with a paper
label
with a serial number, or with a label with a barcode or with a
passive
contactless chip (RFID)? Does only the latter have a (digital)
identity?
Should we build a typology of identities (or "nearly
identities")? If we
can define the wider spectrum of possible identities
definitions, then
we can choose which part of that spectrum we want to address in
the WG.
Finally, objects acting on behalf of their owners or with the
identities
of their owners (e.g. a smartphone sending a notification) seem
to be
something quite common. The owner's identity is then pervasive
and
exists (sometimes partially and momentarily) in several objects
at the
same time. The identity has different forms in the various
objects,
depending on their needs and their capabilities, but it's really
the
same everywhere. I think that situation dramatically needs an
"overarching Identity Framework" to "recognize and manage
identities
across different solutions".
Do you agree?
I'm sorry for posting this so late. Please ask me if my poor
English is
not understandable.
Regards,
