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
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。

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
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.
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。
- 演示
- 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。
私密状态令牌 API
借助 Private State Token API,网站可以向其信任的用户颁发加密令牌,此令牌稍后可在其他地方使用。用户的浏览器安全地存储令牌,之后可在其他环境中兑换这些令牌,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.
