http://techcrunch.com/2016/05/19/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. The new technique unearthed by the study is based on fingerprinting a machineâs audio stack via the AudioContext API. So itâs not collecting sound played or recorded on a machine but rather harvesting the audio signature of the individual machine and using that as an identifier to track a web user. I understand that these methods are not possible without javascript, are they? The example provided in the webpage: https://audiofingerprint.openwpm.com/ uses fingerprintjs2 library. Any thoughts?
