Browser fingerprinting is one of the most accurate ways to track a particular device on the internet.
When matched with other data like email, IP Address,location, device model, CPU model, screen size, browser window size, browser position, graphics card, battery level, browser version, browser extensions, operating system, time zone, cookies, visited addresses and others, the effect is major. There is no surprise that a given user can be picked up from the crowd by Google based on browser fingerprinting data alone. For example, if an add tracker identifies a visit to lets say Y0uTube, then amazon, then other random site, it can be determined that it was the same device and then the events can be easily correlated. The add tracker will give a user an ID at first encounter, then it will use the same ID at subsequent encounters and the available data will be collected and processed. With Google, this is possible because the same add tracker will be present in multiple websites. This way, Google adds will track you all over the internet. Those trackers collect informations beyond the scope of serving adds only, as they are often presented by Google, but not exclusively. They also collect location, for example. And because it can be matched to your phone, it will be easy to observe all the places you’ve been. This is sold to data mining companies. The browser fingerprint can be matched now to an IP and an email address used to log in an website. You as the user are now associated with this fingerprint and the data will be accumulated about you. There is no easy escape from this point. Even if you change the browser, you will use the same data for login and you will visit roughly the same websites, so your identity will be easily recognisable.
One of the scariest propagators of Browser Fingerprinting is facebook.
Because the facebook L1ke button is in essence an add tracker, every website with a L1ke button has an active spyware. So after browsing the internet , the moment you log in facebook you are unmistakeably identified and all data associated with you like friends, contacts, and so on become a big database. This extreme tracking is unmatched even by the big Governmental players. They are not concerned though, they can always buy your data (and they will someday) without being accused of direct mass surveillance or other wrongdoing.
This is one of the reasons facebook is one of the biggest violator of internet privacy. If you use facebook and the associated apps, all your internet activity will be attached to your real identity.
As long as you stick with the facebook account, nothing will prevent the theft of your info.
The only good decision would be to leave facebook. There are other platforms out there.
Hard pill to swallow for many, I know that!
If you use facebook and/or other facebook owned apps on LineageOS devices you can nulify half of the effort spent for your privacy. facebook will know who you are and will sell your data to whoever wants to buy it without any remorse and, of course, without any warning or notification.
Browser fingerprinting data propagation is highly dependent on the browser, search engine and apps you have installed and use. An add blocker will make a lot of difference. Some care should be taken and awarness is advisable when deciding the utilisation patterns.
