Firefox 58 vs canvas fingerprinting: Ο Firefox στην έκδοση 58, θα είναι ο πρώτος μεγάλος browser που θα κάνει κάτι για το fingerprinting. Η συλλογή fingerprinting μέσω canvas χρησιμοποιείται από websites για να συλλέξουν δεδομένα από στοιχεία HTML. Με τον επερχόμενο Firefox θα χρειάζεται να δώσετε την άδειά σας πριν επιτραπεί η συλλογή data, as with Tor Browser.
Fingerprinting has started timidly, but has gained prominence in recent years as an approach by Companies that collect user tracking data without having to report it to the end user. 
It works by monitoring the pro itselfletterof browsing, and not the tracking of a beacon placed on program περιήγησής σας, όπως κάποιο cookie, ένα Flash LSO (τοπικό κοινόχρηστο αντικείμενο) ή μια price DOM storage.
Beacons can be blocked or deleted, while fingerprinting is not.
Browser fingerprints
Fingerprinting uses information passively collected by your browser, such as version number, operating system, browser resolution, screenς 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 doctormaterial footprint, and the more ingredients included, the easier it is to track you down.
One of the most popular components uses HTML canvas.
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 pictures (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.
To combat the Canvas fingerprint, Firefox developers chose the Tor Browser's opt-in approach instead of an absolute rejection of the fingerprint. We will see it live on the upcoming Firefox 58.
