E-epidemiology also refers to the large-scale epidemiological studies that are increasingly conducted through distributed global collaborations enabled by the Internet.
Efficient number crunching computing, using modern analytical tools and simulation based inference procedures allow knowledge to be extracted from the resulting large and complex data-structures.
Web portals directly connected to the studies enables instant feedback and information to the participants.
[citation needed] Important aspects of e-epidemiology include the development of security and confidentiality preserving solutions to protect individual integrity and research data ownership.
Accurate security programmes and firewalls are a critical condition for handling personal records over the Internet.
