Abstract

Our aim is to generate a privacy preserving micro data table for release, from the original table. A Privacy Preserving Transformation (APPT) tool developed, transforms both the numerical and nominal sensitive attributes to preserve privacy while maintaining the information and hence the utility. Any type of mining tasks can be performed on the released Micro data table (transformed table) without any modification in the algorithms. The data mining results obtained do not disclose sensitive information but the data owners and authorized persons can be allowed to interpret the actual sensitive values. The tool can be used to merge the partitioned data, whether it is horizontally and vertically partitioned. Experiments performed using Real Adult dataset prove that the Released table preserves privacy which is as good as any other popular anonymization techniques but reducing information loss. The tool does not require any domain expert. But the cost we pay for the privacy is the high security for the centralized server.
