| Abstract(in English) | Re-identification attacks for pseudonymized location traces have been widely studied to understand the risk of location privacy. The re-identification attack for pseudonymized traces can be regarded as biometric identification based on behavioral characteristics of users. However, no studies have evaluated the risk of re-identification by comparing it with the performance of biometric identification such as fingerprint identification and face identification, to our knowledge. In this paper, for more intuitive understanding of the risk of re-identification, we evaluate the BSE (Biometric System Entropy) of pseudonymized traces using the Foursquare dataset, and compare it with the BSE of fingerprint and face and password entropy of PINs. |
