Our problem is that we (at least initially) needs strong encryption that can
work in a multitude of settings, standalone or networked. We don't have the
capacity to develop, maintain and support several encryption systems.
Remember that our software is not only now used throughout South Africa -
it's been piloted in Mozambique, Malawi, India, and Nigeria, and a number of
other developing countries have expressed interest.
These confidentiality issues are one main reason for us to have exclusively
focused on Health management Information Systems using anonymised,
aggregated data up to now. The pressure for us to expand into surveillance
systems are currently very high, though, with most superusers and top
managers constantly pushing the issue (current surveillance systems are
mostly highly fragmented systems based on Epi Info for DOS, with nearly
non-existent encryption).
So my question still stands: Does anybody know of a simple-to-implement
strong encryption method that would work with a variety of standard
SQL-compliant Data Base Management Systems? I don't care if the development
environment (tool) is proprietary, as long as we can use it to develop an
encryption scheme/tool that can be distributed for free.
