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

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.

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

借助具有独立分区状态的 Cookie (CHIPS)，开发者可以选择将 Cookie 纳入分区存储空间，每个顶级网站都有单独的 Cookie 罐，从而提高用户隐私保护和安全性。此演示说明了其工作原理。

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

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 框架

Privacy Sandbox Demos 框架基于 Privacy Sandbox API 提供实用指南、示例代码和演示应用。这些指南旨在帮助企业和开发者调整其应用以及他们支持的企业，以适应不使用第三方 Cookie 的 Web 生态系统。
