Browser fingerprinting is a common but controversial technique. Many websites — and their advertisers — try to track you by collecting as much information about your browser, including its plugins and extensions, and your device, such as its make, model, and screen resolution, to create a “fingerprint” that’s unique to you.
Who does it? Google. Duh. How about DuckDuckGo?
We checked the site using CanvasBlocker, a popular privacy extension used to block trackers from fingerprinting your browser
DuckDuckGo fingerprints browsers. Or, does it? DDG CEO Gabe Weinberg:
Fingerprinting-detection libraries unfortunately create false positives because they don’t anticipate good actors using some browser APIs for non-nefarious purposes for which they were designed. We know this not only because we’re falsely identified here (and have been elsewhere) but because we are building this type of detection into our mobile app and browser extension and don’t similarly want to make false claims.
An issue that should be settled is not.
