Browser Fingerprinting Privcay and Security Issues

What is Browser Fingerprinting?

You have various fingerprints and comprise devices, computer fingerprint, or the browser fingerprints. All these offer chances to harvest information about remote computing devices for the strict purpose of identifying users.

While the data points appear harmless, there is hardly any chance you can have the same browser information as another user.

In the basic form, these fingerprinting techniques give a site the capacity of identifying or being able to re-identifying users who go to the site. Just some of the gatherable information is the operating system, language, time zone, screen resolution and many more.

Add to this a user agent or device through the configuration settings or a few other characteristics.

What makes matters worse is that these fingerprints can fully or partially identify individuals or their devices even if they disable the use of cookies. It is a threat to online privacy and security, so it is good that you can do something about it.

Canvas Fingerprinting

Canvas fingerprinting is one of the newer methods used to gather personal data from a browser. Websites, which are written in HTML5, can contain small snippets of code.

Programmers use the element inside called the ‘canvas,’ and which they initially used to contain graphics on web pages.

Now, it can be used to harvest data and pose a threat to any user’s security and privacy. The canvas element, stores font size, and background color settings. It takes this from the visiting web browsers, and thus using them for fingerprinting.

Unlike cookies, no information is stored on your device and will be stored elsewhere.

The Difference Between Browser Fingerprinting vs. Your IP Address
