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
Topics API 让浏览器无需使用第三方 Cookie 即可与第三方分享用户兴趣信息。它允许在不跟踪用户访问网站的情况下针对用户兴趣投放广告 (IBA)。本演示展示的是 API 的实际应用示例。
演示
Colab
通过此 Colab，您可以轻松加载 Chrome 用于根据主机名推断主题的 TensorFlow Lite 模型。
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
共享存储空间
Shared Storage API 提供可跨网站使用的存储空间，也就是说，您可以在一个域上存储值，然后从另一个域读取该值。您可以自由设置数据，但从存储中取出数据的方式会受到限制。此演示展示了其工作原理。
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 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.
