#22just inject this with your favorite JS injection plugin
let oldTanh = Math.tanh;
Math.tanh = x => oldTanh(x) + Math.random()/10000000;Re: Since Chromium 148, Math.tanh is now fingerprintable to link underlying OS
#23Can't we make fingerprinting illegal, as in, jailtime illegal? Would not solve everything but still help a lot.
I don't think it'd be possible to define fingerprinting narrowly enough to not also outlaw perfectly normal and legitimate usecases.

#24> One tanh call on the right input is a per-OS signature. Claim macOS, return Linux math bits, and you have contradicted your own User-Agent. They (or rather the LLM that wrote this) missed that this is possibly fingerprintable to browser version range, which is slightly more interesting. Most users aren't spoofing their user agent headers to be a different operating system. Most fingerprinting solutions aren't tryin…
> Most users aren't spoofing their user agent headers to be a different operating system. The people behind the LLM behind this blog post are. They're trying to pretend their robots are people to sell other websites' data to their customer. It's easier to pass bot detection gates if you pretend to be a physical machine running Windows or macOS than if you honestly admit you're using Linux on a VM.
The Internet is a cesspool of scams now

Why should it be illegal for me to recognize the way you walk into my store, even though you're wearing a mask and a trenchcoat? Some vague sense of indignation? Yeah, tracking bad, I get it, but are whatever damages that kind of legislation would prevent (probably nothing measurable) really more important than fixing the easy, in our face social problems that politicians could instead be focusing on?
Because you don't have a right to know everything about me, follow me to my home, my purchasing preferences, and so on and so forth.

#26Interesting reporting, marred by obvious llm-slop-sounding writing. "You are not building..., you are ..."
Why "slop-sounding"? It's definitely LLM slop.
Man, why the fuck don't they just make a powerpoint with bullet points if all the sentences are like that.

#27Kind of a smart move by this company: write up an AI analysis of all fingerprinting techniques in hopes they get fixed after outrage so their scraping company can make more money. If it weren't for companies like this, fingerprinting wouldn't be so ubiquitous and the internet would be a better place in general. I prefer articles like this coming from the other side of the battle (fingerprint.js and friends) because a…
I disagree, fingerprinting is necessary to track humans and it will be used regardless of scrapers being there or not.

If you have that right, the public should have the right to know you're doing this before they enter your store, so they can avoid it.
Same with the websites, they should, legally, have to say they're about to fingerprint you so that you can close your browser tab and never come back.

Why don't you ask browser developers to stop adding features helping fingerprinting? Browsers even have some API for tracking ad clicks (attribution API or something) and user interests tracking API which nobody of the users needs.

#30What I don't get is that Chrome is hundreds of megabytes of just executable code, I assumed they statically linked half the userland. Also, I though tanh isn't a function, but an intrinsic emitted by the JS JIt that uses CPU instructions - which might be fingerprintable as well, but it's weird that for a math operation, you need to branch to a 'dlsym()' function.
