Browser Fingerprinting: Privacy's Silent Killer?

Researchers developed FPTrace, a framework assessing fingerprinting-based user tracking by analyzing ad system responses to browser fingerprint changes. The study revealed tracking persists even after cookie deletion, with fingerprint alterations impacting ad bidding and HTTP records. Worrisomely, users opting out of tracking may still be tracked via fingerprinting. Researchers advocate for stronger browser defenses and regulation, hoping FPTrace helps audit websites and providers engaging in such practices without consent.
