The Aggregation Service offers many benefits to publishers, advertisers, and ad tech professionals.
- Privacy-preserving measurement: The Aggregation Service enables the measurement of ad campaign performance without needing to track individuals, ensuring user privacy.
- Secure environment: The service leverages a Trusted Execution Environment (TEE) to decrypt and process data, ensuring that the raw data remains protected within a secure, isolated environment.
- Report summarization: The service efficiently summarizes the processed data, providing clear and concise summary reports for analysis and campaign optimization.
- Noise addition: Noise is introduced into the final summary reports, preventing re-identification of individuals within the aggregated data and further enhancing privacy. Despite the added noise, accurate aggregate data can be used for effective measurement and analysis.
- Report accounting: The Aggregation Service efficiently tracks the aggregatable reports to prevent their reuse, ensuring that each report contributes only once to the final output and preventing any attempts to manipulate the aggregated data.
