Audio fingerprinting being used to track web users, study finds

A wide-scale study of online trackers carried out by researchers at Princeton University has identified a new technique being used to try to strip web users of their privacy, as well as quantifying the ongoing usage of some better-known tracking techniques.

Other tracking techniques they looked at include WebRTC IP, canvas fingerprinting, canvas font fingerprinting and battery API15.
While privacy tools such as Ghostery and Firefox’s third-party cookie blocker were rated as effective by the researchers, they found “obscure trackers” pose more of a challenge, concluding that: “The long tail of fingerprinting scripts are largely unblocked by current privacy tools.”
