Interactive Method for Publishing Tabular Data with Privacy Preservation

Data publishing in healthcare raises major concerns due to the sensitive data involved. In this paper, we propose an interactive method for data publishing with privacy preservation between the Manager (data publisher) and the Miner (data requester), in which the Miner specifies the manipulations accepted in the data based on the privacy level defined by the Manager. The method works with structured tabular data and privacy regarding protecting records and attributes. Through a use case, we demonstrate that the use of the proposed method made it possible to prove privacy in data publication, with an impact of less than 3% on the usefulness of the data.
