プライバシーサンドボックスデモ

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.

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.

Demo

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).

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.

Docs

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.

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.

ユーザーエージェント文字列削減

ユーザーエージェント文字列削減は、パッシブフィンガープリントに使用される可能性がある、ユーザーエージェント文字列で共有される個人識別情報を最小限に抑えます。リソースリクエストの User-Agent ヘッダーの情報量が削減され、特定の Navigator インターフェースから返される値の情報量も削減されました。このデモでは、新しい UA 文字列の値を試すことができます。

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.
