The Private Aggregation API securely passes raw data from the Shared Storage or Protected Audience APIs by encrypting the information within reports, without revealing individual level data. Here’s an overview of how the Private Aggregation works with other Privacy Sandbox technologies:
- When used with Shared Storage, Private Aggregation generates aggregate reports on cross-site data from Shared Storage in a secure environment. This is particularly useful for demand-side platforms (DSPs), publishers, and third-party measurement companies.
- When used with Protected Audience, Private Aggregation generates aggregate reports from buyer and seller data that include information from the remarketing and custom audiences built with Protected Audience. This is particularly useful for DSPs and supply-side platforms (SSPs).
The Private Aggregation API is a game-changer for the advertising industry, as it offers:
- More effective campaign measurement: Advertisers and ad tech providers can gain insights into campaign performance, such as reach and frequency, without relying on tracking individuals across the web.
- Improved audience insights: Publishers and advertisers can better understand their audience's interests and behaviors in a privacy-preserving way.
- Development of new privacy-centric advertising solutions: Private Aggregation opens up opportunities for innovation in areas like cross-site measurement, without compromising user privacy.
