Is there a program similar to SETI@home to help fight terrorism?  I
have heard of one that searches for anthrax prevention but I am
wondering about one that catches encryption of text or images.  Which
government agancy could this be suggested to if this doesn't exist?

Thank you for your question.

You're already aware of the Anthrax Research Project:

Clearly yours in an idea that's already getting attention.  There's an
interesting ABC News article related to your inquiry, called
"Digital Warriors--Artificial intelligence could help spot future
terrorism attacks." (copyrighted)

Also, work now being done at a company called Applied Systems
Intelligence,
< www.asinc.com/ASINCMainProducts.htm >
is described on their webpage as follows:
"The parallel problem of detecting related events, that appear to be
random and seemingly unrelated, is a critical capability that is
needed, but to this date has not been developed. (An example of
detecting these types of critical events is the early detection and
alerting of terrorist activities leading to an attack on a government
facility.) ASI’s approach to solving this problem is an event
retrieval mechanism concept called Knowledge-Aided Retrieval iN
Activity Context (KARNAC)."

The Company doesn't appear to be using a SETI-type distributed
computing approach to the problem, however.

There have been distributed approaches to code-breaking.  The
best-known of these are the RSA and CSC contests:

< www.distributed.net/csc/index.html.en >

Combining these approaches would constitute the anti-terror program
that you envision.

I hope you find this information useful, and thanks for using Google
Answers!

I still need clarification on the last part of the question.  Who in
the government would be interested in this line of problem solving? 
Thanks for your help.
