RE: Moving "C"onsent from Tracking Status to Permitted Use?

Hi JC,

 

OK my wording was a bit loose, but my point was that it does not let the
user stop the collection of data, and it defaults to opted-in. All these
opt-out models need cookies (choice.microsoft.com just sets a 1 year
persistent cookie named vickoptout=1) , and so people end up being reverted
to opted-in if they delete cookies. As they probably did that in order to
protect their privacy their wishes in those cases are being disregarded. 

 

It is a nice page but I can see how it could be improved a lot by using the
DNT API. It should default to opted-out if DNT is set, and then use the
web-wide consent API if they opt-in. Once they opt-in you can cookies to
give them fine-grained control over ads as you do now. 

 

Until the API is supported you could just set an opt-in cookie
(vickoptin=1?) and use that to override DNT - you could even respond with a
Tk: C header J. Then as browsers come in supporting the API you just use
that. 

 

Around 10% of web requests that we see now have DNT set and about 60% of
them are IE so maybe MS should take a lead in honouring it?

 

Cheers

 

 

Mike

Mike,

 

To respond to your early comment about the use of the AdChoices icon. I'm
hoping you will clear up the misconception about its purpose being solely
for refusal of OBA. The icon is to permit users to express their Advertising
Choices. If you click on the icon on Microsoft's http://msn.com page it will
take you to http://choice.microsoft.com/ where you can opt-out of or opt-in
to OBA. You can also use it to go to the industry opt-out page or our
dashboard where you can select your advertising interests, among other
things.

 



AdChoices can be easily adapted to support DNT and I hope you will help
spread the word about its versatility. J

 

Best regards,

JC

Hi Bryan, 

 

Great post regarding:

 

Exactly the point I have been making for some time, that the whole
UA/UI-based approach to tracking preference management will not scale, when
on my smartphone I may have three different Web browsers installed, and a
dozen or more hybrid Web apps (which to me are indistinguishable from native
apps); as well as several other devices: laptops, desktops, tablets,
web-enabled TVs/bluray/car/appliances etc etc. And multiple users of many of
those devices, who all will need to be served equivalently under a common
preferences UI unless it considers persona.

 

We've already solved that problem using all current Web standards including
DNT. It scales to every device and every browser and allows the user
complete control over what gets shared with a content provider.

 

Cheers,





 

Peter
