Our society is in the midst of a vast and pervasive data revolution. Enormous amounts of data are produced and
exchanged daily and people are increasingly using all sort of digital tools in almost any aspects of their life. Health
is no exception. A 2013 survey shows that 75% of European hospitals have some type of electronic health records
(EHR) system in place.1 In 2014, six out of ten Europeans have searched for health information on the Internet2 and
the download of health and well-being applications in 2016 has reached 3 billion globally.
