Unique in the Shopping Mall: On the reidentifiability of credit card metadata

In a new study published in Science, a group of researchers from the Human Dynamics group led by student Yves-Alexandre de Montjoye, found that "anonymized" credit card users could be reidentified with just a few pieces of information. The researchers analyzed transactions made by 1.1 million people in 10,000 stores over three months. Although the information had been “anonymized” by removing names and account numbers, each purchase made by the same credit card was tagged with the same random identification number.  more ›
