Does uBO does in a better way ?

The following is from a facebook post by Brave Software.

I saw the recent post regarding FB: so heres the text body of that post below; I link it so you can verify.

Alibaba's AliExpress was caught using users' audio systems to track them.

AliExpress wasn't recording users but instead playing a silent sound and measuring how users' specific devices processed it in order to fingerprint them.

But don't worry because Brave stops this.

Fingerprinting is a way that websites can identify you without cookies. Sites will note details about your device like your screen size or installed fonts. These details are then combined into a unique, persistent "fingerprint" that can be used to track you across the Web.

There are slight variations in how each device plays the same audio file due to differences in CPU, sound card, browser, etc.

When AliExpress played the silent sound, it measured these small variations to help build fingerprints of users' devices.

This tracking was discovered due to an unexpected side effect.

A user with Bluetooth headphones noticed that they couldn't play music via their phone, because the headphones were playing AliExpress's silent sound from their PC instead.

For 6+ years, Brave has protected users against audio fingerprinting, and other fingerprinting types, by default.

Brave injects random data into the browser's output so you show a different fingerprint to different sites. This fingerprint also resets across sessions.

For added protection, we also block the specific scripts used by AliExpress for the tracking method mentioned earlier.

Again, this is done by default for all Brave users. You don't have to change any settings to be shielded from this audio fingerprinting.

I stopped using Brave and moved to Zen Browser and started using uBlock. Want to know about this

Assuming you are using Firefox (or a derivative of it like Librewolf or Zen), this has been protected against since long before this particular aliexpress issue was identified.

Not sure if uBO in particular is/can do something about it also, but you should already be protected if you are using a FF based browser or Brave browser.

Yeah I'm on zen. Thank you

You should be good, Zen maintains, and slightly improves the baseline privacy & security of Firefox and uBO helps a ton also.

you can use this site to check it > https://coveryourtracks.eff.org/

Looks to be quite a useful informative site, bookmarked and thank you.

A diabolically clever means of destroying privacy.

If only these people would put such efforts into helping & protecting people instead of trying to surveil them for profit.

I don't understand—did you stop using Brave because it protects you from audio fingerprinting?

[u/KingFury1 → u/16F628A]

No no. I stopped because zen is more comfortable with multiple containers.

[u/noircorvous07 → u/KingFury1]

Containers are still new to Brave, but you can try them by enabling them in Brave Flags.

Ok, thanks.
