TY - Generic T1 - A Generalisation-based Approach to Anonymising Movement Data T2 - 13th AGILE conference on Geographic Information Science Y1 - 2010 A1 - Gennady Andrienko A1 - Natalia Andrienko A1 - Fosca Giannotti A1 - Anna Monreale A1 - Dino Pedreschi A1 - S Rinzivillo AB - The possibility to collect, store, disseminate, and analyze data about movements of people raises very serious privacy concerns, given the sensitivity of the information about personal positions. In particular, sensitive information about individuals can be uncovered with the use of data mining and visual analytics methods. In this paper we present a method for the generalization of trajectory data that can be adopted as the first step of a process to obtain k-anonymity in spatio-temporal datasets. We ran a preliminary set of experiments on a real-world trajectory dataset, demonstrating that this method of generalization of trajectories preserves the clustering analysis results.
