Privacy-preserving data cube for electronic medical records: An experimental evaluation

Highlights • An EMR data cube is a complex of EMR statistics and has great potential for medical researches. • There is a need to anonymize EMRs because they may lead to privacy violations. • Various anonymization methods perform differently in terms of the efficiency and effectiveness of the data cube. • This study assesses privacy-preserving EMR data cubes anonymized by the various methods. • Our findings help to adopt the best anonymization method with consideration for the EMR analysis environment and goal of the EMR analysis.
