Font Fingerprint Blocker

code3

Requirements:
Virtually Undetectable
Has whitelist

Does anyone know of one?

@code3 , I think that Trace protect several fingerprints. Better CyDec, but it isn' OpenSource, it gives all data that the site required, but all are random fake values.
Website https://www.cydecplatform.com The extension is free, but not so the full platform, which works also with an desktop app and the browser, also free a limited desktop app to spoof and obfuse system data

code3

@Catweazle CyDec doesn't have great whitelist support; Trace is also proprietary software and I don't think it protects font fingerprints. (Does it?)

Catweazle

@code3 , no, Trace is OpenSource, but has a premium version which permit some stettings in the UI.
https://github.com/jake-cryptic/AbsoluteDoubleTrace/ , other developers use an Donation buton, these use the system with some goodies in the UI and som extra lists in premium version for a few bucks.
There also a Canvas Blocker, which protect from font fingerprint, but Trace also have a Canvas fingerprint blocker

I will look at CanvasBlocker. If Trace prevented font fingerprint that would be great but I don’t think it does.

Catweazle

@code3 , yes and it surprised me a little. Source code open but with copyright. Something like CC licence?
Anyway, its certainly one of the best extension.

@catweazle I don’t see an option to prevent font fingerprint in canvas Blocker.

Catweazle

@code3 , no problem

@catweazle I see, unfortunately that’s not what I want, scrambling the fonts is too detectable and can break sites.

Catweazle

@code3 , for what i know, you can spoof the font fingerprints, but this also give you an unique fingerprint, or you can randomize the value, what realy protected privacy.

What about uBO No remote fonts feature?

Catweazle

@stardust , I think, that is something different from Font Fingerprint

Stardust

@catweazle

but blocking remote fonts eliminates fingerprinting, right?

Catweazle

@stardust , try in Browserleaks

code3

@stardust I don’t use uBO, I use the inbuilt blocker.

While I do block some remote font sources, the thing I’m worried about is detecting fonts installed on my computer.

@stardust , I randomize the Font Fingerprints, no problems for now, only condition is, that the randomized value correspond to Fonts which are standart in the Web.
For Example, this one works very well. You can test it on Browserleaks, every reload shows other values with this.
