I once had a customer who asked many questions on how to integrate a hardware random number generator to a computer application.

This is not uncommon; most customers use a hardware random number generator for a game application, a lottery, or possibly a statistical science application. This was a bit different, after a while it came out what he was trying to accomplish.

He ran security for a diamond mine. In such a mine a security issue is that a worker can find a diamond in the dirt, and then pocket it and take it home. So workers are searched when they leave work. But, for cost and convenience, they don't search all workers when they leave the mine. He was looking for a solution, where guards could not select who is to be searched. Co-operation between a worker and a guard should also be eliminated.

An additional complication -- this was in the south part of Africa -- that possibly a majority of the guards was white, while the workers was mostly black. But not all workers are black, some are also white. Some kind tricky situation emerge, of a political nature, that could be solved eliminating the thought that the white gourds never select a white worker for search.

The solution used a serial port random number generator such as the TRNG9803.
