Several of Internet's top websites use device fingerprinting technology to track users without their knowledge, a new study has revealed.
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 user's browsers.
The device fingerprinting or browser fingerprinting circumvents legal restrictions imposed on the use of cookies and ignores the Do Not Track HTTP header.
