Identificare un PC via Internet grazie al time drift del clock

Time-drift technique fingers PCs | The Register

Bruce Schneier, the noted cryptographer, described the approach as "nice work"; but the technique has already generated a fierce debate about its reliability. Mostly, the cryptographic community is discussing the ability of remote device fingerprinting to yield evidence good enough for a court of law - are clock skews stable on a particular PC? But there are wider concerns about device fingerprinting: taken at face value, the technology could end anonymous net access, a cause for celebration for repressive governments everywhere.
