Privacy Sandbox 演示

演示和协作项目将引导您全面了解 Privacy Sandbox API。

我们提供了许多 Privacy Sandbox API 演示。大多数示例都需要您熟悉相关 API，因此，如果您尚未阅读文档，请查看我们列出的链接以及演示。

演示和 Colab

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

借助 Topics API，用户的设备可以根据用户的活动来观察和记录用户可能感兴趣的主题。然后，该 API 允许调用方（例如广告技术平台）访问这些主题，而不会泄露有关用户活动的其他信息。以下资源提供了 API 的实际使用示例。

面向 Web 上 Topics 的资源

Android Topics 的资源

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.

Related Website Set 是一种公司声明网站之间关系的方式，以便浏览器允许出于特定目的进行有限的第三方 Cookie 访问。Chrome 将使用这些声明的关系来决定在第三方上下文中何时允许或拒绝网站访问其 Cookie。

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

借助 Private State Token API，网站可以向其信任的用户发放加密令牌，这些令牌稍后可在其他地方使用。令牌由用户的浏览器安全地存储，然后可以在其他情境中兑换，以确认用户的真实性。查看此演示中的 API。

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.
