RE: Indirect DNT Processing (Proposed)

Shane,

I believe that's how we designed the "site wide exceptions" to not affect RTB in any way.
At this point we're trying to distort the "no sharing" prohibition to have DNT not impacting in any possible way RTB. I hardly see any difference with a "status quo" since, according to you, everything is already covered by contracts between platforms and bidders.

We provided a couple of examples of how RTB could work. Only one edge case remains  where:
1 No site wide exception has been granted,
2 Bidders need both URL and UID,
3 Actually one of the bidders which has been picked-up by the ad-exchange, also has a UGE.

As I understand, only in that case would your proposal actually bring any value otherwise the answer would simply be "D". This is a very unlikely situation which would only benefit to the few actors which could actually have a web wide exception.

A more balanced solution would be to rely on site-wide exception to support RTB.

Jeff,

 

I don't believe I'm suggesting we "prop up" the Exchange marketplace - rather I'm suggesting we understand it and develop a reasonable implementation approach that takes the technical realities into consideration.

Shane:

 

There is no reason to prop up programmatic, given its dominance and capabilities.  What is required are safeguards-including via DNT.

 

If the group can't ensure DNT works via the dominant tracking modality, it's a scarlet letter for WC3.

Jeff,

 

I'm not saying that at all - and I think you know better.  I'm saying we need to find solutions within DNT that support the programmatic marketplace.

Is what you and Yahoo saying that DNT shouldn't protect privacy from the widespread and unregulated uses of audience buying/programmatic advertising?  DNT must address programmatic, which is already the majority of the display market and-as we all know-will dominate (even across platforms).

Rob,

I'm the Chair of the Metadata Working Group at the IAB so thank you for calling that out.  But understand even that standard will take time to roll out and is meant to compliment - NOT DISRUPT - the current workflow.  The discussions around RTB are highly disruptive and BREAK the current model - with no easily solutions at hand.  That is my core concern - there is a lack of consideration within the group of this critical dynamic.

Well, change is a constant factor. For example, the IAB is working on adding metadata all the way down the ad chain. There is no reason why the current protocols are cast in stone. The whole purpose of DNT is to have in impact on current ad practices.

Disagree - any new standard should respect the marketplace that it 
expects to adopt it.  If we force considerable changes in the current 
ad ecosystem you won't have any adoption (meet in the middle versus 
force all in one direction).

Vincent,

Some bidders may only be contextually targeting information (not 
cross-site or "different context") and will need to the URL to 
determine content on the page.

Shane,

My idea was to keep it as a one step process where the bid request 
would only contain the UID and only the win notice would contain the 
URL. I still don't understand how the ADX can broadcast (URL,UDI) in 
the bid request without violating the "Third party compliance"
requirement to not share data
(http://www.w3.org/2011/tracking-protection/drafts/tracking-complianc <http://www.w3.org/2011/tracking-protection/drafts/tracking-complianc> 
e .html#third-party-compliance [1]). Sending only the UID could solve 
this problem.

That being said, a two step process would actually work very well.
Especially, if UGE status are directly reported in the "matching 
tables" hosted by the ad-exchange; in that case the "additional step"
would have no impact at all on the transaction latency.

Vincent,

The Bid occurs in a single pass so all relevant information is 
passed as part of the "offer to bid" transaction (URL, UID) the 
bidder would then check their UGE records for that particular UID to 
then determine if leveraging profile information would be possible in 
this transaction. Attempting to make this a "two-step" process would 
slow down the transaction too much in a world where Ad Exchanges 
already struggle to meet SLAs with a single call structure.

Shane,

I have a clarifying question. In the precise case of RTB, when DNT 
is set, is it possible to only include in the Bid Request information 
about the user (i.e. the user id) but not about the current network 
transaction (i.e. no information related to the visited website)? 
That would allow website to check that they have a UGE before 
bidding, information about the visited website would then be only 
transmitted to the winning bidder.

This option would still allow RTB to take place while preventing 
information about a network transaction to be shared with third 
parties.

Objet : Indirect DNT Processing (Proposed)

TPWG,

I was asked to develop language for consideration of how to manage 
DNT signals within Real-Time Bidding (RTB) environments such as an Ad 
Exchange. I've up-leveled the concept to "Indirect DNT Processing" to 
cover scenarios where a user's signal may move from a direct client 
interaction to one between servers (server-to-server).

[Normative]
For Servers in direct communication with the User Agent that then 
communicate further with other parties within the same transaction 
but outside direct communication with the User Agent, those Servers 
MUST convey the current DNT flag relayed to their domain to those 
other parties. In cases where other parties have recent knowledge of 
their own domain's DNT flag or UGE MAY process the request leveraging 
that information but MUST respond appropriately in the status 
response that they have done so - which, in turn, MUST then be 
conveyed by the Server to the User Agent.

[Non-Normative]
This is intended to facilitate indirect communications through a 
transitive passing of permission to allow for DNT processing to occur 
even when a processor doesn't have direct access to the User Agent. 
If the processor has direct information about their own domain's DNT 
setting with the User Agent, such as their last direct interaction 
with the User Agent, they may want to consider this in their 
transaction handling.

Question - While from a policy perspective the passage of the STATUS 
RESPONSE value makes sense I'm not sure if this works as cleanly with 
the current TPE handling of those statuses. Should we add a new 
flag/field to state a response is being conveyed from another party 
as to not confuse the User Agent into thinking the response is coming 
from the server in which it is in direct communication?
