New: Audio Fingerprinting of Browsers.

Post by JB28 » Thu Jun 02, 2016 0:18

I saw a news report yesterday about a new method that is being used to "fingerprint" browsers.

I imagine most readers here will know about the EFF's "Panopticlick" test.

Here is the news article in The Hacker News, about this new method of audio browser fingerprinting:

http://thehackernews.com/2016/05/audio-fingerprint.html

I quote from the article: "......the newest tracking technology unearthed by the researchers is the one based on fingerprinting a machine’s audio stack through the AudioContext API."

"The method has nothing to do with the device's microphone, as it relies on the way a signal is processed. "

When I read it, I quickly thought the people at JohnDoNym might like to know about this.

(I'm not a very "technical" person; I can't write code or scripts for instance, and I haven't been here for a long time, but I thought this information might be useful. it appears to be new information.)

If I understood the article correctly, NoScript will block audio fingerprinting. Can anyone verify that?

@frustrated you'r right

https://www.w3.org/TR/webaudio/
This specification describes a high-level JavaScript API for processing and synthesizing audio in web applications.
no js,no audio fingerprinting

test it

only if you allow js for

https://audiofingerprint.openwpm.com/

AND

ajax.googleapis.com

Don't you Remember,
The Fifth of November,
'Twas Gunpowder Treason Day,
I let off my gun,
And made'em all run.
And Stole all their Bonfire away.
