- [Host] As part of their study,
the researchers looked at 15 months of human mobility data
for 1.5 million individuals.
Here's their key finding.
Human mobility traces are highly unique.
Again, human mobility traces are highly unique.
Your spatial temporal data is highly identifying.
By spatial temporal data, I mean where you are and when.
In fact, in a dataset where the location
of an individual was specified hourly
and with a spatial resolution
equal to that given by the carriers antennas,
four spatial temporal points were enough
to uniquely identify roughly 95%
of the individuals in that dataset.
In short,
your digital fingerprint is about three times,
I repeat three times,
more identifiable than your human fingerprint.
