【C6】______ , credit cards use was just as【C7】______ at identifying someone as mobile phone records, the study found.
Knowing the price of a【C8】______ could boost the risk of re-identification by 22 percent.
"Even data sets that【C9】______ coarse information at any or all of the dimensions provide little anonymity(匿名)," the study, led by Yves-Alexandre de Montjoye at the Massachusetts Institute of Technology and colleagues at Aarhus University in Demark, revealed.【C10】______ some of the specifics were stripped from credit card data, such as【C11】______ the general area where a purchase was made instead of the【C12】______ shop, or expanding the time range to 15 days【C13】______ one, a person who would have believed themselves believed themselves【C14】______ could be re-identified with "just a few more【C15】______ data points", said the study.
