A privacy preserved model for medical data sharing in telemedicine

Abstract

In the converged Information and Communication Technology (ICT) era, medical data sharing has emerged as an important element in the healthcare industry. Hospitals within a Telemedicine system would like to share their private local databases with other hospitals. However, they do not agree to keep a copy of their database into a central server. The central repository (data warehouse) model is not secure because too much control will be granted to the central site. In order to fully utilize the distributed and heterogeneous resources, a secure and privacy preserved model should be used to reach the balance between knowledge discovery and data privacy protection at the same time. We proposed a privacy preserved model to securely share the data for Telemedicine system. © 2009 Springer-Verlag Berlin Heidelberg.
