Abstract—In order to avoid the issue of privacy disclosure caused by publishing information in the location-based social network (LBSN), a method for detecting privacy disclosure is proposed in this paper. Firstly, we use the Naive Bayes classification model to classify released contents. Secondly, we extract the features of privacy disclosure in released contents according to the special categories and combine with the time and location released at the same time. Finally, we use the decision tree method to determine the possible privacy disclosure. Comparing to the Native Bayes and support vector method, the result shows that the method proposed in this paper carry out the privacy disclosure detection much effectively.
