Why the collision of big data and privacy will require a new realpolitik
By David Meyer
People’s movements are highly predictable, researchers say, making it easy to identify most individuals from supposedly anonymized location datasets. As these datasets have valid uses, this is yet another reason why we need better regulation.
More information and SOME commentary from BBC:
Scientists say it is remarkably easy to identify a mobile phone user from just a few pieces of location information.
Whenever a phone is switched on, its connection to the network means its position and movement can be plotted.
This data is given anonymously to third parties, both to drive services for the user and to target advertisements.
But a study in Scientific Reports warns that human mobility patterns are so predictable it is possible to identify a user from only four data points.
