The document summarizes the Safe Share project, which aims to enable the secure exchange of health data between research sites for medical research. It establishes a higher assurance network using encrypted overlays between network nodes. It also explores implementing an authentication, authorization and accounting infrastructure to allow researchers to access data and systems using their home institution credentials. Several pilot programs are underway to test the network and authentication capabilities. The overall goal is to accelerate medical research while maintaining strict security and privacy of sensitive health data.
