Intelligent Tracking Prevention (ITP)

Intelligent Tracking Prevention is a feature developed by WebKit, an engine used in Safari and other browsers, that reduces cross-site tracking by further limiting cookies and other website data. It was designed to recognize and prevent domains with tracking capabilities from following users across the web using first-party cookies.

How does it work?

  • Intelligent tracking prevention incorporates a machine-learning model (machine learning classifier) based on statistics collected by the browser to evaluate which domains can track users’ actions across different websites.
  • If the machine learning classifier identifies that a particular first-party cookie can be used for tracking. Then, the cookie will be blocked unless you use the storage access API to ask users if they allow using your cookie.
