Make sure big data doesn't land you in big trouble

Nice article.I sit on a Research Ethics Committee, and we are getting an increasing number of applications from researchers wanting to mine health-related data. So many come along with proposals that have not considered how easy it can be to reconstruct "anonymous" data so that the PII can be derived. I'll use those entropy figures the next time someone comes up and says "but there is no way our data can reveal the subject!"
