A new study has uncovered that 145 of the Internet’s 10,000 top websites track users without their knowledge or consent. The websites use hidden scripts to extract a device fingerprint from users’ browsers. Device fingerprinting circumvents legal restrictions imposed on the use of cookies and ignores the Do Not Track HTTP header. The findings suggest that secret tracking is more widespread than previously thought.
