Browser fingerprints and online privacy.  We know who you are!


We’ve written about online privacy and tools that require complete privacy: proxies, VPNs, and similar software. But we didn’t think about it, the sites already know who you are! The method is known as Device Fingerprinting or Browser Fingerprinting… In this post we will talk about what is Browser Fingerprint and then see if we have any methods to avoid tracking or tracking you.

Browser fingerprints

The collection of your data by websites you visit using any browser and identifying you based on this data is called Bowser Fingerprinting. Almost every Internet user has different settings for their browser. Not only browser information, but websites can run JavaScript or Flash to find out your computer’s screen type, system fonts, Cookies etc.

But if you are using a proxy and VPN, does it matter? A Proxy just changes your location. It does not add or remove extensions from your browser or change its settings. Similar VPN will also not change the screen resolution and pixel depth. None of these can prevent a website from asking for the fonts installed on your computer, or hide their sequence so that it looks like another computer.

In other words, they cannot change or erase your Browser Footprints… While there are options now, most browsers have the option to ask websites not to track you, but websites may or may not accept the request. You can also use some third party tools to help you cut, track and track you. They work, but they cannot block requests from websites.

Going back to what Browser Fingerprinting is, there are third-party companies that take it upon themselves to identify you among the millions of other people visiting a particular site. Most of the data is obtained by requesting your browser: the number of extensions, installed extensions, browser settings, cookies that you have allowed to store on your computer, and similar data. Some companies add a script to find out your system configuration. In short, they first identify you and then track you, usually for profit!

Now that you know that websites can identify you through various methods, you might want to know how to avoid this kind of surveillance.

Avoid, disable browser fingerprints

While there are some plugins for Chrome and Firefox that claim to accomplish the task by accidentally enabling and disabling add-ons, I don’t think that can actually work. In addition, with the help of these specific plugins, it will inform websites about your browser. In addition, they only enable or disable other plugins, so websites can always read which plugins and extensions are present, even if they are disabled.

You can manually add some plugins before starting your browsing session. And every time you can remove them and add other plugins. This is also not a reliable answer to preventing or disabling browser fingerprints.

The main problem is that they can query your computer using Javascript or Flash code… Flash code can provide good information about your system.

I’m not sure, but I think I read somewhere that you can disable system requests by disabling Flash on your computer as websites use Flash scripts to query your computer. If any of you have information on this, please share.

Some might think that using InCognito or InPrivate mode may I help. But without extensions, it still makes your browser unique. “Hey this is the guy who always uses InCognito mode … but I can read the extensions he has in his browser … wait, I can also see his browser settings“.

Among several steps you can take to prevent or disable browser fingerprints, you can also try the following:

  1. Disable JavaScript. Disabling JavaScript is powerful protection against browser fingerprints because it strips off the code that websites use to detect plugins, fonts, super-cookies, and more, but it can affect your browsing experience.
  2. Use TorButton… It standardizes most of the characteristics and strings of the browser, and can also block JavaScript in the browser. Plugins are available for browsers as well.
  3. Learn how to block canvas fingerprints in Chrome and Firefox.
  4. The CoverYourTracks website shows you how trackers see your browser, giving you an overview of your most unique and identifying characteristics.

Here’s what I was able to learn about in-browser fingerprints. The only good news is that not many sites use this technique – yet!
