Hospitals within a Telemedicine system would like to share their private local database 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 was granted to the central site. In order to fully utilize the distributed and heterogeneous resources, a secure and privacy preserved model should be used. We proposed a secure data sharing model to facilitate this problem.
