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
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
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
- 标题演示：建议采用这种效果更好的方法。
- JavaScript 演示：如果您无法修改标头，请使用 JavaScript Topics 方法。
- Topics API Colab：使用 Chrome 用于从主机名推断主题的 TensorFlow Lite 模型进行实验。
- 面向 Web 的 Topics 文档：详细了解 Topics 的运作方式以及如何实现 Topics。
Android Topics 的资源
- 示例应用：请参阅 Kotlin 示例应用或 Java 示例应用，以指导您完成集成。
- Topics API Colab：针对主题分类器模型测试不同的应用信息组合。
- Android 版 Topics 文档：了解 Topics 在 Android 上的运作方式。
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、第三方 iframe 中的广告以及第一方情境中的广告的转化情况。在此演示中，广告客户使用广告技术提供商在发布商网站上投放广告。
演示
Noise Lab
当收集器批量处理可汇总的报告并由汇总服务进行处理时，系统会在生成的摘要报告中添加随机数据，以保护用户隐私。使用 Noise Lab 尝试不同的值，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的报告中收集的数据，添加噪声，并返回最终的摘要报告。所有这些操作都在可信执行环境 (TEE) 中完成。
Colab
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 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.

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.
