[RISKS] Risks Digest 24.01
------------------------------

Subject: Hermann Chinery-Hesse and software in Ghana

There is an interesting article in the August 2005 issue of IEEE Spectrum
on the above subject.  Mr. Chinery-Hesse runs a very successful software
business in Ghana.  Some of the high points:

* Software that is lean and efficient, so it runs well on old PCs such as
   386/486.  These are affordable in Ghana.
* Software design for robustness under third-world conditions.  For example,
   frequent writes to disk to minimize work lost of the power goes off, as it
   frequently does.
* Rather extreme measures to protect proprietary software, such as updates
   installed in personal visits by software company employees.  This to cope
   with conditions in a country where any sense of ethics is practically
   nonexistent.
* Shunning of open source software, on the grounds that having the source
   makes it too easy for unscrupulous users to modify the code so as to line
   their own pockets.

This last item could well be criticized as security through obscurity.
Surely the incentives are there for users to make a considerable effort to
tamper with closed source proprietary software.  One could argue that open
source software would be easier to audit for unauthorized modifications.
But then who audits the auditors?  And how can they be sure that the code
actually running in the machine is accurately represented by the source code
they can see.

This suggests a larger research topic: how can we make computer systems that
are guaranteed to "work right" when they are to be installed in a den of
thieves?  Seems like this has applicability to the problem of electronic
voting systems in the U.S.
