通过演示和 Colab 实验,您可以详细了解 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
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
借助 Topics API,用户的设备会根据用户的活动,观察和记录用户似乎感兴趣的主题。然后,该 API 允许调用方(例如广告技术平台)访问这些主题,而无需透露与用户活动相关的其他信息。以下资源提供了该 API 实际运作的示例。
有关“Google 搜索上的主题”的资源
- 标头演示:这是推荐的、性能更出色的方法。
- JavaScript 演示:如果您无法修改标头,请使用 JavaScript Topics 方法。
- Topics API colab:试用 Chrome 用于根据主机名推断主题的 TensorFlow Lite 模型。
- 适用于网络的 Topics 文档:详细了解 Topics 的运作方式和实现方法。
Android 主题的资源
- 示例应用:请参阅 Kotlin 示例应用或 Java 示例应用,以便了解如何进行集成。
- Topics API colab:针对主题分类器模型测试不同的应用信息组合。
- 适用于 Android 的 Topics 文档:了解 Topics 在 Android 上的运作方式。
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。
演示
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。
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.
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.
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 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.
