DuckDuckGo is using the Canvas DOMRect API on their search engine. Canvas is used to make unique geometry measurements on target browsers, and DOMRect API uses rectangles. This can be verified with the CanvasBlocker Firefox add-on by Korbinian Kapsner. DDG has recently been redirecting some website navigations to cute pictures with remarks about their privacy promises. The organization is now seeking to expand their Internet presence. DDG are without question data brokers, and commercial websites that make promises like DDG does will not survive for long if they actually keep them.
While I’m at it, Whonix forums also use Canvas identification. Hmm…
Those interested may find a bit more certainty (for now) with the searx and YaCy projects. Searx is a customizable meta-search engine whose source code is available at Github. Anyone can create a searx-instance for public or private use, and some are onion services. YaCy is a P2P search engine that can be accessed via a client proxy or websites offered by volunteers who allow access to their own installation.
