Identity Management--In Privacy We Trust: Bridging the Trust Gap in eHealth Environments

Healthcare systems are moving to decentralized scenarios, forming a mesh of mobile services and care providers. A rapidly growing number of users aren't shy about using new services on their home computers, mobile phones, and laptops. Identity management solutions, deployed for ease of use, control the data that users provide to individual healthcare services. These solutions raise trust and privacy concerns about who owns users' data, how to control its spread, and how to build trustworthy associations between healthcare providers. Reputation systems can enhance eHealth systems by bridging the gap between strong contractual agreements and first-time domain exchanges.
