The current thesis compares and evaluates well-known anonymization methods that have been proposed in the literature for moving object trajectories. The comparison is conducted between the existing anonymization methods that are applied to different data sets for all their variations and different levels of anonymity. Through data anonymization and evaluation criteria application, various some results are derived that are capable to lead to the extraction of critical conclusions which give the advantages and disadvantages of anonymization methods to help defining the optimal use of them depending on the characteristics of the datasets that are going to be processed.
Initially, the problem of privacy protection and the potential threats that may arise due to malicious use of personal data are presented. Well-known techniques that have been proposed in the literature for relational but mainly for moving object data whose preservation is the goal of this work are introduced. Then, step by step the whole process that generates the assessment of the methods is presented. Finally the analysis of the results and the conclusions of the thesis are presented.
