According to the study by KU Leuven-iMinds researchers, 145 of the Internet's 10,000 top websites use hidden scripts to extract a device fingerprint from users' browsers.
The method of tracking digital fingerprint is the practice of collecting properties of PCs, smartphones and tablets to identify and track users, and include screen size, version of installed software and plugins along with installed fonts.
Device fingerprinting can be used for various security-related tasks, including fraud detection, protection against account hijacking and anti-bot and anti-scraping services, but it is also used for analytics and marketing purposes via fingerprinting scripts hidden in advertising banners and web widgets.
The researchers have developed a tool called FPDetective to detect websites using device fingerprinting technologies.
