Canvas Fingerprinting

Canvas is an HTML5 API for drawing graphics and animations on a web page with JavaScript.

Being able to identify users is the first step to following them. This tracking technique is based on the fact that the same graphics and animations are rendered differently on different computers.

It monitors the features of users' devices or browsers to create users' profiles. User-specific tokens can be created when combined with information such as operating system, screen resolution, browser and browser version, language, and time, which alone will not be enough to identify people.

It is possible for users to be identified on other sites through these tokens and to display personalized advertisements to them.

There are approximately three thousand different data points in our digital footprints, which are collected by the websites that almost all of us have visited.

When all these data points are combined, users' privacy is violated without even knowing it, in a much more dangerous way compared to cookies or the methods I mentioned above.
