Abstract: In a networked communications system comprising a client unit, a
secured host server, and a company subscriber unit, a method for providing
secured commercial transactions via the networked communications system.
The method includes the steps of providing a secured transmission path via
the networked communications system between the client unit and the secured
host server, presenting the client unit with an order form in which
commercial information is to be entered via the secured transmission path,
receiving the commercial information transmitted via the secured
transmission path by the client unit at the secured host server,
maintaining the commercial information solely in the dynamic memory of the
secured host server, encrypting the commercial information in response to
the step of receiving the commercial information, erasing the dynamic
memory of the secured host server in response to the step of encrypting the
commercial information, and forwarding the encrypted commercial information
via the communications network from the secured host server to the company
subscriber unit. Attorney, Agent, or Firm: Patnaude Videbeck & Marsh;

First Claim: Show all 8 claims
What is claimed is:
1. In a networked communications system comprising a client unit, a
secured host server, and a company subscriber unit, a method for providing
secured commercial transactions via the networked communications system
comprises the steps of:
* providing a secured transaction path via the networked communications
system between the client unit and the secured host server;
* receiving encrypted commercial information transmitted via the secured
transmission path by the client unit at the secured host server;
* reencrypting substantially all of the once encrypted commercial
information in response to the step of receiving encrypted commercial
information; and
* forwarding the reencrypted commercial information via the communications
network from the secured host server to the company subscriber unit.
