Patient openness to sharing data is critical for the success of big data in healthcare. However, there is a tension between privacy and disclosure. Sharing one's health information online can be a rewarding yet risky behavior. The goals of the project are twofold: 1) to understand people's mental model regarding health-related privacy online and to evaluate its relationship with trust and disclosure management, and 2) to identify design solutions for privacy protection that will facilitate online health information disclosure, featuring a visual tool to ensure consent process.
