Using Anonymized Data for Classification

In recent years, anonymization methods have emerged as an important tool to preserve individual privacy when releasing privacy sensitive data sets. This interest in anonymization techniques has resulted in a plethora of methods for anonymizing data under different privacy and utility assumptions. At the same time, there has been little research addressing how to effectively use the anonymized data for data mining in general and for distributed data mining in particular. In this paper, the authors propose a new approach for building classifiers using anonymized data by modeling anonymized data as uncertain data. In their method, they do not assume any probability distribution over the data. Instead, they propose collecting all necessary statistics during anonymization and releasing these together with the anonymized data.
