BigQuery data clean rooms

Seamlessly create and manage a secure environment for privacy-centric measurement, data sharing, and collaboration across organizations without moving or copying data.

Create your own data clean room in BigQuery in a few clicks. 


What is a data clean room?

According to IAB, a data clean room is a secure collaboration environment which allows two or more participants to leverage data assets for specific, mutually agreed upon uses, while guaranteeing enforcement of strict data access limitations like not revealing or exposing personal data from customers to other parties. DCRs can be designed to serve an array of purposes and deploy different mechanisms, like performing a specific computation for determining matching of audience data between two parties. 

Why do organizations need a data clean room?

With growing consumer privacy awareness and expanding privacy regulatory environments, data sharing and collaboration are increasingly complex and risky. The need for secure and privacy-compliant data sharing is particularly acute in the digital advertising and media industry where signal loss is impacting the ability for advertisers to reach their target audience, optimize ad conversion rates, or even accurately measure and report on campaign results.  

How to select a data clean room that is right for you?

First, consider the compute capabilities and the ability to scale with the size of your data and for the number of collaborators for the clean room. Next, you should think about how quickly you can get a data clean room set up, how quickly you can run queries, and how quickly you can get value from your clean room. Finally, ensure that your data clean room provider offers the privacy protections that meet the needs of your organization.

What makes BigQuery data clean rooms different?

Benefit from the scale of BigQuery without needing to manage any infrastructure. BigQuery data clean rooms give you the controls to prevent your shared data and your query results from being copied or exported by a subscriber. Access easy-to-use privacy functions like aggregation thresholding and differential privacy to protect your sensitive data before it is shared. Streamline your workflows with data connectors and partner integrations. 

How is customer data protected with data clean rooms?

There are several ways data is protected within a clean room. First, data contributors can set privacy policies and analysis rules before making the data available to partners to protect sensitive information. BigQuery data clean rooms will offer cutting-edge data science techniques such as aggregation, differential privacy, and more to anonymize or pseudo-anonymize the data. In addition, BigQuery data clean rooms will enforce export restrictions by default. 

How It Works

BigQuery data clean rooms allow you to create a low-trust environment for you and your partners to collaborate without copying or moving the underlying data. You can perform privacy-enhancing transformations in BigQuery SQL interfaces, and monitor usage to detect privacy threats on shared data.
