Microsoft HealthVault is a health application platform, a set of platform services, and a catalyst for creating an application ecosystem that lets consumers collect, store, and share health information online. The HealthVault platform provides a privacy-enhanced and security-enhanced foundation that can be used to store and transfer information between a variety of providers’ health services and health devices.

Solution providers can use the HealthVault SDK to build applications for the HealthVault platform, and use the HealthVault DDK to build device drivers for HealthVault-compatible devices.
