Publication number: 20110167477Abstract: A hardware-software user connectivity control method and apparatus which provides a secure controlled access arrangement that enables only authorized users to obtain access to stored proprietary information and processing tools/applications on a computer-implemented global monitoring system/network (GMS) used to monitor and diagnose steam turbine power generator equipment and plants. An authentication challenging application (ACA) in the GMS sends a challenge sequence of code/numbers via a non-secure communications link/channel to an authentication response application (ARA) resident on a user/customer computer system. The ARA must respond via the same communications link/channel with an expected response code/number sequence to enable the user's access to the GMS otherwise the communications link/session is terminated. The ARA may optionally be stored on a portable flash memory dongle gaining direct access to the GMS locally.Type: ApplicationFiled: January 7, 2010Publication date: July 7, 2011Inventors: NICOLA PICCIRILLO, GANESH KUMAR
