Browser fingerprinting aims to identify users or their devices, through scripts that execute in the users' browser and collect information on software or hardware characteristics.It is used to track users or as an additional means of identification to improve security.Fingerprinting techniques have one significant limitation: they are unable to track individual users for an extended duration.This happens because browser fingerprints evolve over time, and these evolutions ultimately cause a fingerprint to be confused with those from other devices sharing similar hardware and software.* Both authors are considered co-first authors.identical GPUs and the first to exploit these differences in a privacy context.On the practical front, it demonstrates a robust technique for distinguishing between machines with identical hardware and software configurations, a technique that delivers practical accuracy gains in a realistic setting.
