WebGl and Canvas Fingerprinting Explainer: Sneak Peek on Noise Algorithms

In our latest release, Orbita 112, we’ve made a major update of WebGL and Canvas fingerprinting noises.

This technology is (almost) impossible to see with your naked eye, but it’s critical for your data protection. Let’s take a closer look and explain in simple words how this technology improves the safety of your data online.

Read on – or watch this short explainer video:

With the help of WebGL and Canvas your browser is able to draw 3D and 2D graphics directly on web pages. These features are very useful, but they expose information about your graphics hardware to website trackers.

Every device existing out there will render one image in a unique way (on code level). These differences, however, are invisible to your eye. Because the image rendering information is unique for every computer, it’s useful for generating and tracking your digital fingerprint.

This is how canvas fingerprinting works, and it’s quite hard to deal with. You can’t just throw in random noise parameters: remember that normal users with regular web browsers don’t even know about these. Modern websites are able to instantly determine you from others.

Here’s how the noise works as your Canvas fingerprinting defender. Using custom mathematical algorithms, Gologin adds “noise” to your WebGL and Canvas image code. After that, the same web page image is made completely unique in every browser profile you run in Gologin. That’s why website sees these profiles as separate regular users.

However, not all noises are actually helpful. As we’ve said before, websites are able to determine if the noises are simply generated at random, which is not normal.

This is an extremely difficult task, but that’s exactly what Gologin does well. Our custom noise algorithms keep all your profiles safe and sound.

This makes the image drawn by your computer look both unique and normal in every browser profile you run in Gologin. That’s how your profiles are protected from tracking.

Again, these changes can’t be seen (as shown on GIFs), but the image hash will be different.

Modern website tracking engines lfearn and evolve all the time as well. To keep you protected from WebGL and Canvas fingerprinting, we constantly update these algorithms for your best private browsing experience.

All points green: this is what you should expect from an antidetect browser.
