What is AmIUnique?
AmIUnique is a research website that collects your browser fingerprint and shows how identifiable your device is on the Internet. Once you start a check, it gathers attributes such as browser and operating system version, screen resolution, architecture, fonts, plugins and media devices. It then compares them with fingerprints sent in by other users around the world.
The project studies how varied browser fingerprints are and gives developers data to help them build defenses against tracking. Visitors can view their current fingerprint, see their own history and timeline, and look at global statistics. They can also add data through a Chrome extension and an Android app that scans mobile device fingerprints.
The site is run from the University of Lille in France and is available in English and French. It fits privacy-minded users who want to see how trackable they are, as well as researchers and developers working on anti-fingerprinting.
