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
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
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.
歸因報表
廣告主和廣告技術供應商可透過 Attribution Reporting API 評估廣告點擊和瀏覽、第三方 iframe 中的廣告，以及第一方環境中的廣告轉換次數。在本示範中，廣告主會使用廣告技術供應商，在發布商網站上放送廣告。
示範模式
Noise Lab
當收集器批次處理可匯總報表，並由匯總服務處理時，系統會在產生的摘要報表中加入隨機資料，以保護使用者隱私。使用 Noise Lab 實驗不同的值，瞭解雜訊的影響。
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.
使用者代理程式縮減
縮減使用者代理程式可盡量減少使用者代理程式字串分享的識別資訊，以免遭人用於被動式數位指紋採集。資源要求的 User-Agent 標頭現在會縮減，特定 Navigator 介面的傳回值也會縮減。您可以在這個示範中實驗新的 UA 字串值。
Private State Token API
網站可透過 Private State Token API，向信任的使用者核發加密權杖，供日後在其他地方使用。權杖會由使用者的瀏覽器安全儲存，然後在其他情境中兌換，以確認使用者的真實性。請參閱這個示範中的 API。
Privacy Sandbox Demos Framework
Privacy Sandbox Demos 架構提供以 Privacy Sandbox API 為基礎的食譜、程式碼範例和示範應用程式。這些指南旨在協助商家和開發人員調整應用程式，並支援商家適應沒有第三方 Cookie 的網路生態系統。
