Subject: [Asrg] Not again - another challenge/response patent

This is ridiculous. Yet another bloody challenge-response patent. :(

From: Brad Templeton <brad(_at_)templetons(_dot_)com>

Here is the patent reference.
Francisco, CA 94105) Appl. No.:   921950  Filed:  August 26, 1997

I have prior art.  I proposed this exact system, to a tee, in 1996:

http://groups.google.ca/groups?hl=en&lr=&ie=UTF-8&oe=UTF-8&selm=56luge%246on%40bertrand.ccs.carleton.ca

Although Google lists the date as 17 November 1996, according to my
archive, I posted the article on Sat Nov 16 21:48:50 1996 EST.
