Getting started with Media DCR

Decentriq's Media Data Clean Rooms (Media DCRs) provide an intuitive no-code interface to use first party data for gaining insights and optimizing advertising campaigns.

Decentriq's unique security stance, running the whole platform within fully verifiable confidential computing, ensures that neither Decentriq nor the cloud provider can access any data processed in its Media DCRs (note that almost any data collaboration usecase can be implemented using the Advanced Analytics DCR).

Media DCR use-cases and collaboration types

Collaboration types are configuration options to enable use-cases. Currently, the Media DCR supports the following use-cases:

• Insights: In this use-case, the advertiser and the publisher combine their first-party data to derive insights about the advertiser’s customers based on the publisher’s attribute data. These insights are always aggregated and thus do not constitute personal data. This use-case is enabled by the Insights collaboration type.
• Remarketing: In this use-case, the advertiser wants to reach existing customers on the publisher's site. This is achieved by joining the advertiser's audience with the publisher's and exporting the overlapping users for activation. This use-case is enabled by the Remarketing collaboration type.
• Prospecting: The goal in this use-case is for the advertiser to reach new (prospective) customers. This use-case is enabled by two collaboration types:
  • Lookalike audiences: In this collaboration type, a lookalike model is trained on the advertiser's and publisher's data. This model is then applied to the publisher's data to find similar users. As the output of the training step is a trained model which is then applied only to the publisher's data, there is no transfer of personal data from the advertiser to the publisher.
  • Rule-based audiences: In this collaboration type, the advertiser can create audiences by filtering existing audiences based on attributes and combining them with other audiences.

Participants of a Media DCR

There are several roles involved in a Media DCR collaboration. The following matrix summarizes their permissions.

	Provision data as advertiser	Provision data as publisher	See insights	Create audiences	Export audiences	Access DCR configuration, audit log
Advertiser	Yes	No	Yes	Yes	Yes*	Yes
Publisher	No	Yes	Yes	No	Yes**	Yes
Agency (optional)	No	No	Yes	Yes	Yes*	Yes
Observer (optional)	No	No	Yes	No	No	Yes

note

• Insights are only available if the Insights collaboration type is enabled.
• Creating and exporting audiences are only available if at least one of Remarketing, Lookalike audiences or Rule-based audiences collaboration types are enabled.
• *Exporting audiences by the advertiser or agency user is only possible if the Media DCR is configured to allow it, see Creating a Media DCR.
• **The publisher can only export audiences after they have been made available by the advertiser or agency user.

A Media DCR collaboration in short

These are the basic steps to run a collaboration in Decentriq.

1. Create Media DCR: The advertiser creates a Media DCR and invites the publisher to collaborate (or vice versa). Optionally, agency and observer roles can be added to the collaboration.
2. Connect data: Both parties onboard their data to the Media DCR.
3. Gain insights: By leveraging the insights provided in the Media DCR, the advertisers can plan campaigns, improve targeting, and achieve better results.
4. Create audiences: The advertiser creates audiences and makes them available for activation.
5. Activate audiences: Depending on the configuration of the Media DCR, the audiences can then be sent by the publisher to the SSP or by the advertiser to the DSP for activation.
