On anonymous data publishing based on sensitive tuple cluster
Liu Ha · Journal of Hunan University of Arts and Science · 2013
During the process of data publishing, in order to protect personal privacy, data owner often has to generalize all the quasi-identifier, but in fact the tuple involving personal privacy is very few. So our method starts from the tuples, then divides the remainder into groups according to different sensitive attribute value. Finally, our method selects one tuple per group which is shortest to the tuple involving personal privacy for generalization. The rest tuples need not to be generalized. In this way, our method has improved the utilization rate of the data and reduced the loss of information effectively.
