What is canvas fingerprinting?
Canvas fingerprinting is a method of tracking web users that allows websites to identify and track visitors using the HTML5 canvas element.
Online advertisers and other companies use it to track web users for behavioral advertising and analytics purposes.
How does canvas fingerprinting work?
When a web user visits a website that uses canvas fingerprinting, the website loads a small piece of HTML code.
It includes the HTML5 canvas element.
This code instructs the web browser to create a unique image or fingerprint based on the user’s device and browser.
This fingerprint is then sent to the website’s server, where it can be used to identify and track the user.
Why is canvas fingerprinting controversial?
Canvas fingerprinting is controversial because it is a very effective way of tracking web users without their knowledge or consent.
It can track a user’s online activity, even if they delete cookies or use a privacy-protecting browser extension.
This makes it difficult for users to protect their privacy online.
What can users do to protect their privacy from canvas fingerprinting?
Users can do a few things to protect their privacy from canvas fingerprinting.
- Firstly, users can install a browser extension that blocks the HTML5 canvas element from loading.
- Secondly, users can disable JavaScript in their web browser, preventing the canvas fingerprinting code from running.
- Finally, users can clear their cookies regularly to ensure they are not being tracked by websites that use canvas fingerprinting.
How canvas fingerprinting works in fraud detection.
Canvas fingerprinting is a relatively new technique and is not yet widely used.
However, it can potentially be a powerful tool for fraud detection.
Canvas fingerprinting can be used to track users who are using multiple devices or browsers to commit fraud.
By tracking the unique fingerprint of each device or browser, investigators can identify patterns of behavior that may be indicative of fraud.
Additionally, it can be used to track users who are using VPNs or proxy servers to hide their real IP addresses.
This information can be used to block or investigate suspected fraudsters.
How can you protect yourself from canvas fingerprinting?
There is no foolproof way to protect yourself from canvas fingerprinting.
The best thing you can do is to keep your browser and operating system up to date and use a reputable ad blocker or privacy extension.
Canvas fingerprinting does not operate in isolation. You must combine it with browser fingerprinting, IP tracking, and cookie tracking.
Don’t let it fool you. It is difficult to prevent fingerprints from appearing on canvas. You will only be completely secure if you disable JavaScript.
You cannot view sites that follow you using canvas fingerprinting and other JavaScript techniques until you enable JavaScript rendering.
Even if you could still get into them, the experience would be poor. Websites today rely on JavaScript to enhance user experience. So, what are your other options if you can’t disable JavaScript?
An anti-fingerprinting tool is the most popular technique to avoid canvas fingerprinting and browser fingerprinting.
The Tor Browser is one of the most often used tools for preventing canvas fingerprinting. This tool is at the top of the list of privacy-protecting browsers. It conceals your IP address by using the TOR network.
It addresses the canvas fingerprinting issue. First, it informs users when someone attempts to read data from a canvas. Then, it allows them to send back blank picture data instead of providing false information.
If the Tor browser’s negative reputation prevents you from using it, you may use add-ons such as Adblock Plus, Blur, and Privacy Badger.
The difficulty with blocking canvas fingerprinting is that it tells the sites you know how they function.
As a result, the sites would stop employing canvas fingerprinting. Instead, they would attempt to get your fingerprint through other methods.
Furthermore, using any of these plugins increases the uniqueness of your browser’s fingerprint.
Because of how the web and web technologies are set up today, it is difficult to avoid tracking entirely.
That is unless you are ready to forego the user experience JavaScript provides.
Instead of attempting to prevent canvas fingerprinting, you should allow it to occur. Use the remove plugins (Adblock Plus and Blur) or the Tor browser to remove fingerprints. They will lose if they detect too many of your fingerprints.
The number one way to protect yourself from fingerprinting.
Proxies.
Proxies are like rubber gloves if you want to leave no trace or complete taste without IP bans.
Changing your IP address is the first step to avoiding digital fingerprinting.
IPBurger has top-rated, positive-reviews-through-the-roof kinds of proxies.
