Patent drawing from the official filing.

Google describes a method for selecting digital content, such as ads, while protecting user privacy. The system sends encrypted user data only to trusted partners and shares only general context with untrusted sources before choosing the best content to display.

Why it mattersThis approach could make online advertising more private by limiting how much personal information is shared with third-party ad networks.

In one aspect, a method includes receiving, by a first trusted content platform and from a client device of a user, a first digital component request that includes sensitive data and non-sensitive data. The first trusted content platform sends a second digital component request that includes encrypted user data to one or more second trusted content platforms. The first trusted content platform receives, from each second trusted content platform, one or more first candidate digital components. The first trusted content platform sends a third digital component request to each of one or more second untrusted content platforms. The first trusted content platform receives, from each second untrusted content platform, one or more second candidate digital components. The first trusted content platform selects a given digital component.
