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
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.
Resources for Topics on the Web
- Headers demo: This is a recommended, more performant approach.
- JavaScript demo: Use JavaScript Topics methods if you can't modify headers.
- Topics API colab: Experiment with the TensorFlow Lite model used by Chrome to infer topics from hostnames.
- Topics documentation for the Web: Learn more about how Topics work and how to implement it.
Resources for Topics on Android
- Sample apps: Refer to Kotlin sample app or Java sample app to guide your integration.
- Topics API colab: Test different combinations of app info against the topics classifier model.
- Topics documentation for Android: Learn how Topics works on Android.
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。

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 Set
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。
- 演示
- 提交 JSON 生成器。此工具可生成提交相关网站集 (RWS) 所需的 JSON 资源。
- 文档
用户代理缩减
用户代理缩减旨在尽量减少用户代理字符串中共享的可用于被动式数字“指纹”收集的身份信息。资源请求现在具有缩短的用户代理标头，并且某些 Navigator 接口的返回值已缩短。此演示版应用可让您试用新的 UA 字符串值。
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.
