Mobile location data ‘present anonymity risk’

Eine Studie zeigt: es ist relative einfach aus den Bewegungsprofilen von Handydaten den Benutzer zu ermitteln.

Recent work has increasingly shown that humans’ patterns of movement, however random and unpredictable they seem to be, are actually very limited in scope and can in fact act as a kind of fingerprint for who is doing the moving.
The fairly predictable nature of human movement makes location data more unique to a given user Researchers at the Massachusetts Institute of Technology (MIT) and the Catholic University of Louvain studied 15 months’ worth of anonymised mobile phone records for 1.5 million individuals.

They found from the “mobility traces” – the evident paths of each mobile phone – that only four locations and times were enough to identify a particular user.
