How Canvas Fingerprint Blockers Make You Easily Trackable

Thought your canvas fingerprint blocker made you incognito? Think again.

As many know, canvas fingerprinting is the most recent development in web tracking. In the past, the easiest way to prevent web tracking was to block out the method of tracking entirely. For example, to prevent cookie tracking, you simply disable cookies in your browser.

But when it comes to canvas fingerprinting, things are not so cut-and-dry. In fact, believe it or not, using a canvas fingerprint blocker can actually make you more trackable than if you weren’t using one. That statement defies common sense, but it’s true.

To understand why this is, we must first explore canvas fingerprinting as a whole and how it works, then tackle canvas fingerprint blockers and why they don’t work. To conclude, we’ll cover the only current viable method that does work to stop canvas fingerprint tracking.

If you value your privacy and are currently using a canvas fingerprint blocker, this is must-know information for 2016.
The essence of fingerprinting

Fingerprinting is taking your browser’s attributes and using them to create a tracking profile for you (technically, your computer).

As an example, imagine we start with a group of 1,000,000 visitors.

Imagine 60% of these visitors use Chrome and 40% use Firefox. Our audience is now split into two groups.

From those groups, each visitor will be using a different version of his or her respective browser. That’s another fingerprint. If we exist in an alternate universe where there are only three versions of Firefox, our 40% group is now split into three groups of 13.3% each.
