Abstract(in English) | Data mining can support effective marketing or advertisement based on user' attributes such as sex, age, and current location. However, attackers can identify specific user's attributes if they know the user's location. A lot of approaches for anonymization such as k-anonymity have been proposed to tackle this problem. Existing studies, however, do not take errors of the location information into consideration. Therefore, there is a risk that a specific user's attribute can be identified by an attacker even if their information are anonymized. Moreover, the utility measure proposed in existing studies does not consider errors of the location information. We propose a novel privacy measure and a utility measure that can treat the errors of the location information and propose a method to anonymize the information of users' locations. By simulations, we prove our proposed method can improve the utility of the anonymized information and reduce the risk of the user's attribute being identified. |
