Entrepreneurs and investors already know it: it's time for big changes in healthcare. Technology can make care a lot cheaper and simpler, but a person's privacy should not be compromised. The growing number of healthcare apps, data services and electronic records therefore make the issue of privacy and information security an extremely hot topic.

Moreover, health data is perhaps a person's most sensitive data; the General Data Protection Regulation (AVG) classifies it as special data for a reason. Health data must be handled with extreme care and restraint, but in a world where technology is taking on an ever-increasing role and companies are stepping en masse into healthcare with innovative ideas, is this still possible? How can a person's privacy remain central when healthcare is flooded with innovations, home diagnostic tools and big data commerce?

Central to collaboration around a patient is professional confidentiality. Can this be maintained in a world of computerization and data sharing? Through the healthcare infrastructure of the National Switch Point (LSP, formerly Electronic Patient Record), healthcare providers can share medical data with other healthcare providers in their region. But what if two healthcare providers treating the same patient want to share some information quickly and a simple WhatsApp is the most efficient way?
