デモとコラボで、プライバシー サンドボックス API について学びましょう。
プライバシー サンドボックス API には、さまざまなデモがあります。ほとんどの機能では API に精通している必要があります。ドキュメントをまだ読んでいない場合は、デモとともに記載されているリンクをご覧ください。
デモとコラボレーション
Protected Audience API
The demo uses the Protected Audience API to join ad interest groups on two advertiser sites, and then initiates an on-device auction to select an ad for display on a publisher site.
Topics API
With the Topics API, a user's device observes and records topics that appear to be of interest to the user based on their activity. The API then allows callers (such as ad tech platforms) to access these topics without revealing other information about the user's activity. The following resources provide examples of the API in action.
Resources for Topics on the Web
- Headers demo: This is a recommended, more performant approach.
- JavaScript demo: Use JavaScript Topics methods if you can't modify headers.
- Topics API colab: Experiment with the TensorFlow Lite model used by Chrome to infer topics from hostnames.
- Topics documentation for the Web: Learn more about how Topics work and how to implement it.
Resources for Topics on Android
- Sample apps: Refer to Kotlin sample app or Java sample app to guide your integration.
- Topics API colab: Test different combinations of app info against the topics classifier model.
- Topics documentation for Android: Learn how Topics works on Android.
アトリビューション レポート
Attribution Reporting API を使用すると、広告主と広告テクノロジー プロバイダは、広告クリックと広告ビュー、サードパーティの iframe 内の広告、ファーストパーティのコンテキスト内の広告のコンバージョンを測定できます。このデモでは、広告主が広告テクノロジー プロバイダを使用してパブリッシャー サイトに広告を掲載しています。
デモ
ノイズラボ
集計可能レポートがコレクタによってバッチ化され、集計サービスによって処理されると、ユーザーのプライバシーを保護するために、ランダムなデータが結果の概要レポートに付加されます。ノイズラボを使用して、さまざまな値を試してノイズの影響を確認します。
Aggregation Service
The Aggregation Service is responsible for decrypting and combining collected data from aggregatable reports, adds noise, and returns a final summary report. This is all accomplished within a trusted execution environment (TEE).
Colabs
Shared Storage
The Shared Storage API provides storage that can be used cross-site, meaning you store a value at one domain, then read the value from another domain. You can set data freely, but are restricted in how you get data out of storage. This demo illustrates how it works.
CHIPS
Cookies Having Independent Partitioned State (CHIPS) allows developers to opt a cookie into partitioned storage, with separate cookie jars per top-level site, improving user privacy and security. This demo illustrates how it works.
Related Website Sets
Related Website Sets is a way for a company to declare relationships among sites, so that browsers allow limited third-party cookie access for specific purposes. Chrome will use these declared relationships to decide when to allow or deny a site access to their cookies when in a third-party context.
- Demo
- Submission JSON generator.This tool generates the JSON resources needed to make a Related Website Sets (RWS) submission.

権限に関するポリシー
Permissions Policy を使用すると、デベロッパーは、ブラウザに適用させる一連のポリシーを宣言することで、ページ、iframe、サブリソースで利用できるブラウザ機能を制御できます。このデモでは、利用可能なポリシーを試すことができます。
User Agent Reduction
User-Agent reduction minimizes the identifying information shared in the User-Agent string, which may be used for passive fingerprinting. Resource requests have a reduced User-Agent header now and the return values from certain Navigator interfaces are reduced. This demo lets you experiment with the new UA string values.
Private State Token API
With the Private State Token API, a website can issue cryptographic tokens to a user it trusts, which can later be used elsewhere. The tokens are stored securely by the user's browser, and can then be redeemed in other contexts to confirm the user's authenticity. Check out the API in this demo.
Privacy Sandbox Demos Framework
Privacy Sandbox Demos framework offers cookbook recipes, sample code, and demo applications, based on Privacy Sandbox APIs. These are intended to aid businesses and developers in adapting their applications and the businesses they support to a web ecosystem without third-party cookies.
