Re: WG Review: Protocol to Access White Space database (paws)

[Stephen Farrell <[e-mail]>]

I think this is a good and timely thing for the IETF to do.

One part of this where I think it might be useful to get
some broader input (which may have happened already, I'm not
sure) is the following:

On 19/04/11 17:56, IESG Secretary wrote:

That part is fine but it goes on to say:

I'm told (and believe) this in response to (at least) US
FCC requirements that call for a device ID and sometimes
serial number to be (securely, for some value of securely)
sent with the query.

Those appear to be real regulatory requirements in the
US, presumably so the regulator can stomp on someone who
messes about in the wrong spectrum at the wrong time.
(The link below [1] may be to the right or wrong bit of
those US regulations, I'm not at all sure, not being
from there;-)

So my questions:

Are there may be similar (or conflicting!) requirements
elsewhere?

Does this bit of the charter text need changes to work
well for other regions?

Separately, I'm not sure how to square those kinds of
regulatory requirements with protecting privacy where the
device is carried by a person and has some FCC device ID
(which lots do I guess) and the person might not want
the database operator to know who's asking. But I think
that's ok as something for the WG to figure out since
the charter already calls for respecting privacy.

I'm more concerned in case e.g. some other regional regulation
called for this protocol to be completely anonymous or
something, in which case the current charter text might
be problematic.

Cheers,
Stephen.
