		<summary type="html">&lt;p&gt;Created page with &amp;quot;Adroll&amp;#039;s Tern proposal provides the same functionality as Google&amp;#039;s Turtledove, but allows for multiple organizations to provide this trusted &amp;quot;gatekeeper&amp;quot; service rather than j...&amp;quot;&lt;/p&gt;
&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;Adroll's Tern proposal provides the same functionality as Google's Turtledove, but allows for multiple organizations to provide this trusted &amp;quot;gatekeeper&amp;quot; service rather than just Google. &lt;br /&gt;
&lt;br /&gt;
Adroll's Tern addresses marketers need for accuracy in the audiences they engage. Tern relies on the Turtledove auction mechanism, that separates current context from audience-based bidding.&amp;lt;ref&amp;gt;https://github.com/WICG/turtledove/blob/master/TERN.md&amp;lt;/ref&amp;gt;  &lt;br /&gt;
&lt;br /&gt;
Tern is designed to address the following short comings of Turtledove:&lt;br /&gt;
* Clarifying the necessary inputs to participate in an auction&lt;br /&gt;
* Clarifying how to deal with multiple ad formats&lt;br /&gt;
* Reducing networking overhead by streamlining the data which flows through SSPs&lt;br /&gt;
* Eliminating the need for thresholds on interest group sizes&lt;br /&gt;
8 Reducing the time to potentially deliver an impression&lt;br /&gt;
* Better supporting dynamic creative and product recommendation use cases&lt;br /&gt;
* Supporting some functionality of third-party tags&lt;br /&gt;
* Further specifying auditability of delivered ad creatives&lt;br /&gt;
* Enabling brand safety for both advertisers and publishers&lt;br /&gt;
* Creating a mechanism for trackability metrics&lt;br /&gt;
* Adding a privateData object that can never escape the browser, but improve bidding signals (among potential other use cases)&lt;br /&gt;
* Specifying a mechanism to support creating interest groups based on publisher browsing behavior&lt;br /&gt;
* Allowing publishers to retain control of auction dynamics, while encouraging second-price auctions&lt;br /&gt;
* Specifying frequency capping and optimization&lt;br /&gt;
&lt;br /&gt;
  &lt;br /&gt;
== Impact ==&lt;br /&gt;
Tern, like Sparrow, relies on a trust gatekeeper to operate the auction.  &lt;br /&gt;
&lt;br /&gt;
== Open Questions ==&lt;br /&gt;
* If different buyers send their models to different gatekeepers, how many gatekeepers can one publisher query to retrieve auction information?  &lt;br /&gt;
* What is the time-delay in providing the data necessary for publishers to optimize their revenue?  &lt;br /&gt;
* What is the time-delay in providing the data necessary for marketers to optimize their media spend?&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
