Unique in the Crowd: The privacy bounds of human mobility : Scientific Reports : Nature Publishing Group

Unique in the Crowd: The privacy bounds of human mobility : Scientific Reports : Nature Publishing Group: Finally, we show that one formula determines the uniqueness of mobility traces providing mathematical bounds to the privacy of mobility data. The uniqueness of traces is found to decrease according to a power function with an exponent that scales linearly with the number of known spatio-temporal points. This implies that even coarse datasets provide little anonymity.
 Remember: Your phone is a surveillance device that lets you make calls.
