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
该演示使用 Protected Audience API 加入两个广告客户网站上的广告兴趣群体，然后发起设备端竞价，以选择要在发布商网站上展示的广告。
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
借助 Attribution Reporting API，广告客户和广告技术提供商可以衡量广告点击和观看转化、第三方 iframe 中的广告以及第一方环境中的广告。在此演示中，一位广告客户通过一家广告技术提供商在发布商网站上投放广告。
演示
噪声实验室
当可汇总报告由收集器批量处理并由汇总服务处理时，系统会将随机数据添加到生成的摘要报告中，以保护用户隐私。使用 Noise Lab 尝试使用不同的值，看看噪声的影响。
汇总服务
汇总服务负责解密和合并从可汇总报告中收集的数据、添加噪声，以及返回最终摘要报告。这一切都是在可信执行环境 (TEE) 中完成的。
Colab
共享存储空间
Shared Storage API 提供可跨网站使用的存储空间，也就是说，您可以在一个域上存储值，然后从另一个域读取该值。您可以自由设置数据，但从存储中取出数据的方式会受到限制。此演示展示了其工作原理。
条状标签
借助具有独立分区状态 (CHIPS) 的 Cookie，开发者可以选择将 Cookie 加入分区存储中，每个顶级网站采用单独的 Cookie JAR，从而加强用户隐私保护和安全性。此演示展示了其工作原理。
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。

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.
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.
