A healthcare provider would like to data mine information for research purposes; however, the Chief Privacy Officer is concerned medical data of individuals may be disclosed. To overcome the concern, which is the preferred technique for protecting such data while still allowing for analysis?
To protect medical data while still allowing for analysis, perturbation is the preferred technique. Perturbation involves making small changes to the data to prevent the identification of individuals, thereby ensuring privacy. Access control and encryption secure data access and transmission, respectively, but do not inherently allow for anonymous data analysis. Isolation simply separates data, which might not protect privacy during analysis.
