| Popis: | International audience; The increasing number of published data has allowed the development of data mining, resting on the use of the data to extract knowledge. At the same time, to tackle privacy concerns, anonymization models such as k-anonymity have emerged. Because k-anonymity transforms original data, there is an impact on the utility of altered data for data mining. In this paper, we propose a new writing of the anonymous tables using an anonymization post-treatment. The proposed representation allows to keep more information on the distribution of the original values in the anonymous equivalence classes while being usable directly as input for neural networks for data mining purposes. We test our experimental protocol on two data sets from anonymization research field: Adult data set and an extract from the register of voters of Florida (USA). With these experiments, we show the superiority in data utility of our approach against classical approaches. |
