Topics API

Topics API を使用すると、ユーザーのデバイスは、ユーザーのアクティビティに基づいて、ユーザーの関心を持ちそうなトピックを検出して記録します。これにより、呼び出し元（広告テクノロジー プラットフォームなど）は、ユーザーのアクティビティに関する他の情報を開示することなく、これらのトピックにアクセスできるようになります。次のリソースでは、API の使用例を示しています。

Attribution Reporting

The Attribution Reporting API enables advertisers and ad tech providers to measure conversions for ad clicks and views, ads in a third-party iframe, and ads in a first-party context. In this demo an advertiser uses an ad tech provider to run their ads on a publisher site.

Noise Lab

When aggregatable reports are batched by a collector and processed by the aggregation service, random data is added to the resulting summary reports in order to protect user privacy. Use Noise Lab to experiment with different values to see the impact of noise.

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).

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.

チップ

Cookie の Independent Partitioned State（CHIPS）により、デベロッパーは最上位サイトごとに別々の Cookie jar を使用し、デベロッパーは Cookie をパーティション分割ストレージにオプトインできます。これにより、ユーザーのプライバシーとセキュリティが向上します。このデモではその仕組みを説明します。

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.

Permissions Policy

Permissions Policy allows the developer to control the browser features available to a page, its iframes, and subresources, by declaring a set of policies for the browser to enforce. This demo lets you try out the available policies.

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.
