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
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.
Aggregation Service
The Aggregation Service is responsible for decrypting and combining collected data from aggregatable reports, adds noise, and returns a final summary report. This is all accomplished within a trusted execution environment (TEE).
Colabs
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.
- Docs
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 框架
Privacy Sandbox Demos 框架基于 Privacy Sandbox API 提供实用指南、示例代码和演示应用。这些指南旨在帮助企业和开发者调整其应用以及他们支持的企业，以适应不使用第三方 Cookie 的 Web 生态系统。
