![]() ![]() ![]() The main targets of this are the numerous Web APIs such as WebGL, the Canvas API and AudioContext that make it easy for developers to add graphical and other media features to websites.īut these can also be exploited invisibly by fingerprinting collection. As Brave explains it:īy making your browser constantly appear different when browsing, websites are unable to link your browsing behaviour, and are thus unable to track you on the web. ![]() It sounds almost impossible to stop, but not according to the makers of the Brave browser, which is using its latest developer build to test a new defence against fingerprinting: confusing fingerprinting collection algorithms by randomising some of the data they collect. Having created this, advertisers track users as they browse by noticing every time that pattern pops up on sites across the web.Įven settings meant to protect privacy such as the failed DoNotTrack request can be used to aid fingerprinting collection. It works by analysing dozens of characteristics of a user’s software and hardware setup, which taken together form a unique pattern or fingerprint. It’s called browser profiling, aka the ‘cookieless monster’. More recently, however, browsers and adblockers have started clamping down on this way of profiling users, which is why a second technique dating back a decade has come to the fore. Most people assume third-party cookies are the main way they’re tracked from website to website and across different web sessions, and to a large extent that’s still true. As privacy experts constantly remind everyone, when it comes to tracking using web fingerprinting, users can run, but they simply can’t hide. ![]()
