可匯總報表

Aggregatable reports are encrypted reports sent from individual user devices. These reports contain data about cross-site user behavior and conversions. Conversions (sometimes called attribution trigger events) and associated metrics are defined by the advertiser or ad tech. Each report is encrypted to prevent various parties from accessing the underlying data.

可匯總報表計算

A distributed ledger, located in both coordinators, that tracks the allocated privacy budget and enforces the 'No Duplicates' rule. This is the privacy preserving mechanism, located and run within coordinators, that ensures no reports pass through the Aggregation Service beyond the allocated privacy budget.

Read more on how batching strategies relate to aggregatable reports.

可匯總報表計算預算

References to the budget that ensures individual reports are not processed more than once.

確認聲明

A mechanism to authenticate software identity, usually with cryptographic hashes or signatures. For the aggregation service proposal, attestation matches the code running in your ad tech-operated aggregation service with the open source code.

Read more about attestation.

貢獻者綁定

協調員

Entities responsible for key management and aggregatable report accounting. A Coordinator maintains a list of hashes of approved aggregation service configurations and configures access to decryption keys.

雜訊和縮放

Statistical noise that is added to summary reports during the aggregation process to preserve privacy and ensure the final reports provide anonymized measurement information.

Read more about additive noise mechanism, which is drawn from Laplace distribution.

報表來源

The entity that receives aggregatable reports—in other words, you or an ad tech that called the Attribution Reporting API. Aggregatable reports are sent from user devices to a well-known URL associated with the reporting origin. The reporting origin is designated during enrollment.

共用 ID

A computed value that consists of shared_info, reporting_origin, destination_site (for Attribution Reporting API only), source_registration-time (for Attribution Reporting API only), scheduled_report_time, and version.

Multiple reports that share the same attributes in the shared_info field should have the same shared ID. Shared IDs play an important role within Aggregatable Report Accounting.

摘要報表

An Attribution Reporting API and Private Aggregation API report type. A summary report includes aggregated user data, and can contain detailed conversion data with noise added. Summary reports are made up of aggregate reports. They allow for greater flexibility and provide a richer data model than event-level reporting, particularly for some use-cases like conversion values.

受信任的執行環境 (TEE)

電腦硬體和軟體的安全設定，可讓外部各方驗證機器上執行的確切軟體版本，不必擔心資訊外洩。在 TEE 中，外部各方可驗證軟體是否完全依軟體製造商聲明的方式運作。
