  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.
