Query: Mobile phone data for public health: towards data-sharing solutions that
  protect individual privacy and national security   We outline the constraints faced by operators when deciding to share
de-identified data with researchers or policy makers. We describe a
conservative approach that we have taken to harness the value of CDRs for
infectious disease epidemiology while ensuring that identification of
individuals is impossible. We believe this approach serves as a useful and
highly conservative model for productive partnerships between mobile operators,
researchers, and public health practitioners.
