A new technique is allowing major websites to monitor users’ online activity. Audio Steven Englehardt has nothing to do with a device’s microphone, but instead relies on the way in which the audio signal of each machine is processed. A third -party tracker uses the technique to send low-frequency sounds to a user’s device. Another widely used method to track online users is fingerprinting technique based on the HTML Canvass API and WebRTC local IP discovery. Once processed, a unique fingerprint is created based on the device’s hardware and software capabilities. This is providing a valuable new tool to a range of interested parties, including Princeton University , marketing organisations and law enforcement. Researchers at Google discovered that Google has, through a number of domains, tracked users on nearly 80 percent of all top one million domains using this and other tracking techniques.
