透過示範和 Colab 逐步說明 Privacy Sandbox API。
我們提供多個 Privacy Sandbox API 的示範。大多數的示範都需要您熟悉 API，因此如果您尚未閱讀說明文件，請查看我們提供的示範連結。
示範和 Colab
Protected Audience API
此示範會使用 Protected Audience API，彙整兩個廣告客戶網站上的廣告群組興趣群組，然後展開裝置端競價，選擇在發布商網站上顯示的廣告。
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
廣告客戶和廣告技術供應商可利用 Attribution Reporting API 評估轉換，包括廣告點擊和觀看、第三方 iframe 中的廣告，以及第一方情境中的廣告。在本示範中，廣告客戶透過廣告技術供應商在發布商網站上放送廣告。
示範模式
噪音研究室
如果可匯總報表由收集器批次處理，並由匯總服務處理，產生的摘要報表就會隨機加入資料，以保護使用者隱私。使用噪音研究室測試不同值，瞭解雜訊造成的影響。
Aggregation Service
匯總服務負責解密及合併從可匯總報表收集到的資料、加入雜訊，並傳回最終摘要報告。所有操作都是在受信任的執行環境 (TEE) 中完成。

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.

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.
Private State Token API
有了 Private State Token API，網站就能核發加密編譯權杖給所信任的使用者，供之後用於其他地方。使用者的瀏覽器會安全地儲存這類權杖，並可用於在其他情況下兌換，以確認使用者的真實性。查看這個示範中的 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.
