I'm generally healthy, but lately a few illnesses have struck me down. Could data from my phone or other personal data pick up warning signs to keep me well?
IBM and Apple have massive amounts of data about all of us, from GPS movements to fitness app information. They want to analyse and use the data to predict illness or encourage healthy habits.
It sounds good, but I'm concerned. What say do I have in how my data is used? Can I control who they share it with?
