An intelligent agent (42) and its client (10) communicate using a selector known by both parties to generate and interpret messages and thereby effectively disguise confidential information transmitted in the messages from third parties. Moreover, a neural network is used to implement the decision logic and/or the message disguising functions of an agent (42) such that the logic employed in such functions is not readily reverse compiled or scanned by third parties.

Why it's free to use
- Filed March 12, 1998 and granted May 29, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 12, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 12, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
