A browser fingerprint,
also known as a device fingerprint or browser fingerprinting,
is a technique used to collect and identify information about a user's web browser and device. This information can be used to uniquely identify and track individual users across websites and online services. Browser fingerprinting relies on the fact that each user' s combination of browser settings,
plugins,
fonts,
screen resolution,
and other attributes is often unique or distinctive enough to create a digital fingerprint for that user.
