A scheme of hybrid privacy protection and utility levels for medical data

Healthcare data contains sensitive information, and it is challenging to persuade healthcare data owners to share their information for research purposes without any privacy assurance. The proposed hybrid medical data privacy protection scheme explores the possibility of providing adaptive privacy protection and data utility levels. The evaluation result demonstrates that the scheme can provide adaptive privacy and data utility levels, and the data holder can choose their preferred risk level and data utility through the scheme. The evaluation results on the heart disease and diabetes data demonstrate that the scheme can provide a wide range of adaptive privacy protection and data utility levels to meet different privacy protection and data utility requirements.
