Jason Palmer reports on a new study, “Unique in the Crowd: The privacy bounds of human mobility:”
Individuals can be uniquely identified with just four points of location data, a study of mobile phone records shows.
Countless mobile applications make use of location data, and such information is increasingly used to tailor both services for users and advertisements.
But a study in Scientific Reports warns that human mobility patterns are unique identifiers, even when data are scarce.
