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
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
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.
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.
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.
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 演示框架
Privacy Sandbox 演示框架基于 Privacy Sandbox API 提供实战宝典、示例代码和演示应用。这些技术旨在帮助企业和开发者调整其应用和支持的业务，使其适应没有第三方 Cookie 的网络生态系统。
