相关演示和 Colab 将引导您了解 Privacy Sandbox API。
我们提供了许多适用于 Privacy Sandbox API 的演示。大多数 要求您熟悉 API 请访问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
Topics API 让浏览器无需使用第三方 Cookie 即可与第三方分享用户兴趣信息。它允许在不跟踪用户访问网站的情况下针对用户兴趣投放广告 (IBA)。本演示展示的是 API 的实际应用示例。
演示
Colab
通过此 Colab，您可以轻松加载 Chrome 用于根据主机名推断主题的 TensorFlow Lite 模型。
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 Sets
Related Website Set 是公司用来声明网站关系的一种方式，可让浏览器出于特定目的允许有限的第三方 Cookie 访问。Chrome 会根据这些声明的关系决定何时允许或拒绝网站在第三方环境中访问其 Cookie。

- 提交内容 JSON 生成器。此工具可生成提交 Related Website Sets (RWS) 所需的 JSON 资源。
- 文档
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.
用户代理缩减
“用户代理字符串缩短”功能可最大限度地减少用户代理字符串中可用于被动式数字“指纹”收集等的标识信息。现在，资源请求的用户代理标头也有所减少，来自某些导航器界面的返回值也有所减少。通过本演示，您可以测试新的 UA 字符串值。
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.
