Browser fingerprinting occurs when websites employ special scripts to collect enough information about you, such as your browser, time zone, default language, and so on, to identify you among millions of other internet users uniquely.
Browser fingerprinting (also known as device fingerprinting or online fingerprinting) refers to tracking techniques used by websites to gather information about you. Modern website features necessitate the usage of scripts, which are collections of instructions that tell your browser what to perform.
Working in the background, scripts may recognize a wealth of information about your device and browser, which when combined produces your unique online “fingerprint.” This fingerprint may be linked to you via the internet and several browsing sessions.
How does Browser fingerprinting work?
APIs are built-in software functionalities in today’s web browsers that website scripts may utilize to acquire information. Websites use scripts that run in your browser’s background, allowing browser fingerprinting to work. Scripts are often created for legitimate objectives, such as producing films or images. If we blocked them, most websites would not function correctly – they would “break.”
Because fingerprinting scripts seem precisely like any other script running on a page, no one can tell when websites are gathering their personal information. These scripts collect information such as device specs, operating system, browser settings and plug-ins, user agents, audio and video capabilities, timezone, and more, which may then be assembled into a “hash” or digital fingerprint.
