Submission + - If You Clicked Anything Online, Google Probably Knows About It (softpedia.com)
An anonymous reader writes: Two Princeton academics conducted a massive research into how websites track users using various techniques. The results of the study, which they claim to be the biggest to date, shows that Google, through multiple domains, is tracking users on around 80 percent of all Top 1 Million domains. Researchers say that Google-owned domains account for the top 5 most popular trackers and 12 of the top 20 tracker domains.
Additionally, besides tracking scripts, HTML5 canvas fingerprinting, and WebRTC local IP discover, researchers discovered a new user fingerprinting technique that uses the AudioContext API. Third-party trackers use it to send low-frequency sounds to a user's PC and measure how the PC processes the data, creating an unique fingerprint based on the user's hardware and software capabilities. A demo page for this technique is available.
