Vous pensez être tiré d’affaire en effaçant vos cookies ou en ouvrant un simple onglet en navigation privée ? Navré de vous décevoir, mais les choses sont plus complexes. Chaque navigateur laisse derrière lui une multitude de petits indices techniques qui, une fois combinés, le rendent plus ou moins

La navigation privée ne suffit pas. Découvrez AmIUnique, l'outil gratuit pour analyser l'empreinte numérique laissée par votre navigateur.

any1: > The fingerprinting data is not what is meant by this, only the entropy or probabilities when it says “x out of x” are not to be trusted Does this not make it not very useful though? Like, maybe if the sample size was 10 times higher, there would be matches, but this way I assume that I am unique and think “oh well, might as well not do anything to counter this”. What @SwampTrainer mentions is even worse though: SwampTrainer: > AmIUnique always given me “you’re unique in our database!” results - every time. Same browser, same IP, 3 minutes apart, I’m still “unique” in their database? lol, ok. @sp_rtings : Yes, I agree with this and in reality for me even more browsers are in use (like, less aggressive ad blocking, excluded from VPN etc.): sp_rtings: > There are two strategy: Blend it, or be random every time. And true, the following is also a good point: sp_rtings: > The 10-15 seconds to load is most probably just the polling to their database and compute the results. The actual exchange of data for you to them is a simple packet… like 1 millisecond to send. Data brokers most likely have computing nodes that skim through the data pretty efficiently. And do not get me wrong, my intent is not to discourage from such studies and research but to encourage to get more clarity into this. It just feels like despite so many privacy-related info is found online, they are hard to quantify or even close to useless. One example for this is turning off javascript. I mean.. yes.. but then you can just stay offline as well, as SO many pages depend on it (even this forum, and rtings page as you have shown) that this becomes useless advice. One can also reset the identity often in the Tor Browser. Does it help? Nobody clearly knows.. Beyond the “use different browsers for different things” and “do not change anything if you want to blend in” - but then again, we do not know HOW MUCH you really blend in - there are no real advices to give. Maybe I am just a bit frustrated, that I also can not give clear advice to other privacy-interested friends though, lol.

The whole point of browser leaks is manually gathering that data and analyzing if it changes somewhat or another Of course you cannot check among other devices, unfortunately when it comes to fingerprint tests like those they could only simply be taken with a grain of salt (Maybe except amIunique that one may be the most reliable we have to check among devices but yeah)

Makes sense from that perspective. And thanks for the study! However, reading online about privacy since several years now I’ve come across the whole spectrum of opinions: from “don’t change any setting as it will make you stand out” to “does not matter what you do, they identify you anyway” all the way to “don’t trust the fingerprint tests, like amiunique, as the sample size is too low and results do not mean anything”. That’s why I am wondering which fingerprints are really checked by tracking companies, as loading all the results on amiunique.org for example takes about 10-15 seconds, which seems to be too long of a check for regular pages in the web.

Try comparing AmIUnique JSON files using JSON diff/compare extensions in Firefox. It’ll work fine.

Is AmIUnique comprehensive? If so, then what’s all the other stuff available on BrowserLeaks? (it has 10 different tests to run, each with so much data!) There’s no point of comparing fingerprints unless it is comprehensive. As for running comparisons, I’m not sure how the JSON export from AmIUnique makes it any easier to run a comparison. I tried to compare two such exprts via Meld it made my PC crash (which never happens). I tried Meld with two doc files with Ctrl+A & Ctrl+C BrowserLeaks pastes, but the output made no sense. Just a two notepads full of nonsense characters with lots of highlighting came up.

amiunique reveals my real timezone for some reason im using the flatpak version of firefox could this be whats causing my problem?

There’s a whole conversation about how EFF seems to favor Brave that you and I both participated in: EFF Fingerprint Test Favors Brave? I get the same results, and I can see exactly in detail what in CreepJS what Brave gives up. Mullvad and LibreWolf both leave these areas effectively dead. Don’t you think it’s odd that EFF and AmIUnique disagree so drastically? Like, just objectively - which is right, then? It seems like EFF’s version just isn’t as up to date in the judgement of what’s “random” really is.

Check if your browser has a unique fingerprint, how identifiable you are on the Internet
