The new Google Health is such a bad idea in so many ways it’s difficult to know where to begin. One thing I noticed in the presentation is there is no granularity and no user-configurable permissions control or data sequestering. It’s a typical Google totalising info grab. You link your private data to Google, in some cases information from HIPAA-constrained hospitals or insurers, and in return Google snarfs it up and reserves the right to promulgate it throughout its promiscuously monetising network. They are doing it wrong.
