Consider this. What if I did all the tasks for capturing my medical data? i.e. tasks that an amateur can do using consumer-affordable technology. I am thinking of the consumer profile of an owner of a mobile phone, digital camera or even a flat screen TV.
Then, could I post this medical data to a site and invite doctors or clinical technicians (or whatever they are called) — who could mine this data to propose healthcare advice. Preventive care as well and diagnoses. The power of the network of doctors, who may have treated these illnesses in other parts of the globe, could be very valuable to me (persons posting this data). I could compensate the doctor providing this service in much the same way I would compensate my regular doctor.
It should make sense if we can solve the privacy and commercial challenges associated with this service. Useful, yes! But it shakes the foundations of the societal and commercial models we are used to. Will it work?
