Except that these days, even college students are able to de-cap an
IC chip and analyze the circuitry.

Hmm. That looks something I could pursue.
I started this thread asking about protection schemes for a
proprietary algorithm in the context of trading. The trading
strategy, however, is simply a way to finance what we really want
to do: use this algorithm in hardware devices to analyze other
stochastic time series data for real-world applications such as
medical monitoring devices. For that we need some sort of DSP
with the algorithm embedded in it, but the algorithm needs to be
un-extractable from the chip.
Thanks for the pointer.
