You’re right! I have no idea what you’re talking about!
UnifiedID solution can match disparate unidentifiable IDs across websites, devices, and platforms. Again, this how it does it.
Here’s a step-by-step overview of how it works:
-A user visits a website that contains an ad.
-The DSP receives the ad request.
-The DSP sends back the request and creates a third-party cookie.
-The ad exchange redirects (http redirect) the ad request to the pixel URL on the DMP’s side, passing the user ID in the URL parameter. The DMP reads its own cookie, or creates a new cookie, and then saves the user ID passed from the DSP along with its own user ID in the cookie-matching table.
-If the sync is bidirectional, the DMP makes the redirect back to the DSP, passing its own ID in the URL parameter. The DSP receives this request, reads its own cookie, and stores the DMP ID along with its own ID in the cookie-matching table.
-Now, both the DSP and DMP have each other’s’ user IDs in each other’s databases.
That is where and when the sync occurs. Open the link and look at the graph.

Once the cookie IDs have been synced between two AdTech platforms, they can now share or request data contained in the cookies by referencing each other’s user IDs.
This process is typically done via a server-to-server integration with the data being transferred in large batch files. Although the actual cookie-matching part happens in real time, sharing the data between platforms happens at a specified time, e.g. once a day.
This is between AdTech companies on synched IDs. The website publisher (Nike in this example) is not involved in this process. The publisher does not read the TTD or other AdTech cookie data or obtain the ID.
From TTD privacy policy. Of this data this is only how it is shared.
Data that is in our Platform is pseudonymous, which means that it does not directly identify people.
We share pseudonymous IDs that we think might be related to other pseudonymous IDs with clients and partners that use our AdBrain product.
Only pseudonymous to pseudonymous. Ie AdTech companies in the consortium.
In the terms and conditions for using the TTD platform.
Company shall not (i) import any personally identifiable information into the Platform, including by using TD’s ad tags or pixels to gather such information, and (ii) combine any TD Data or Business and Campaign Data with any personally identifiable information.
Company would be the client in an agreement with TTD and TD is the Trade Desk.
In your example you are inserting Nike or a comparable into a process where it doesn’t exist and saying that TTD is sharing data in a way in which their privacy policy doesn’t say they can do, and inferring Nike is doing something in which the terms and conditions prohibit.
So unless you have a reportable instance of this occurring and not a made up hypothetical can we close this out and move on to another topic.
