Abstract

Personal location information is a type of physical privacy information, and the adversary can identify true identities of users according to background knowledge. For analysis of the user privacy problem, this paper modeled the attack process where the adversary inferred true identities and devised a Bayesian inference method to measure the degree of identity leakage from personal location data. By comparing observed location data with background knowledge databases, this method could re-identify users' true identities. Using the dataset on real road networks, experiments show that an untrusted LBS can obtain true identities with high probability by collecting user queries. This study demonstrates that the disclosure of high-precision personal location information can lead to a high risk of identity privacy breach. [ABSTRACT FROM AUTHOR]
