It works by monitoring the pro itselfof browsing, and not the tracking of a beacon placed on περιήγησής σας, όπως κάποιο , ένα Flash LSO (τοπικό κοινόχρηστο αντικείμενο) ή μια DOM storage.

Browser fingerprints

Fingerprinting uses information passively collected by your browser, such as version number, operating system, browser resolution, ς σας, τη γλώσσα, τη λίστα με τα plugins του προγράμματος περιήγησης και τη λίστα γραμματοσειρών που έχετε εγκαταστήσει.

There are many different ingredients that can be used to create a doctor footprint, and the more ingredients included, the easier it is to track you down.

To Canvas fingerprinting is a surface that a browser can "paint."
Your browser gets instructions from websites to do something. Let's say an image extracted from the canvas goes through a fragmentation function that produces an identifier.

Different graphics cards and operating systems work slightly differently, which means that if you give two different web visitors identical (and same instructions), will produce different identifiers.

Complex instructions can produce several ID variants, which makes it Canvas fingerprinting a powerful data collection tool.

The more complex the instructions, the easier it is to understand the differences between the browsers, and of course the identification of the end user.
