Supervised access computer network router
First Claim
1. A network management system connected to a client computer via a first network, said client computer having an associated client activity monitor, said network management system comprising:
- (a) a router-switch connected to said first network and to a second network;
(b) a network server comprising a computer hardware platform having a processor and a computer-readable storage medium in communication with said router-switch;
(c) a status monitor which receives status messages from each of said client activity monitor; and
(d) a network activity monitor which receives activity information from said client activity monitor and stores said activity information for subsequent retrieval, said activity information comprising captured screen images from computers connected to said first network;
(e) a display module operable to display said activity information stored by said network activity monitor on a computer display after a period of user inactivity;
said network server causing said router-switch to restrict said client computer'"'"'s access to said second network if the time between receiving of consecutive said status messages by said network server from said client computer exceeds a predetermined amount of time.

Abstract
A system for monitoring and regulating computer usage on a local network is disclosed. Computers on a network are configured with a client activity monitoring module that collects activity information including screen captures, keyboard activity, and/or information relating to network communications and sends the collected activity information to a network activity monitor for storage and later retrieval. Each computer on the local network periodically verifies that its client activity monitor module is operable. If a computer fails to send such verification, the system restricts network access by that computer, thus enforcing compliance with the activity monitoring system. The system further provides means for automatically displaying the collected activity information, including through screen savers, automatically changing desktop background images, and pop-up or sidebar windows. The system thus enables review of computer activities for appropriateness by both supervisors or parents as well as by peer users without requiring the reviewer to take affirmative steps to retrieve the activity information.
