1. A system for providing secure access to a server management system comprising:
- a workstation including a video monitor, a keyboard, and a cursor control device for receiving keyboard or cursor control device commands from an authorized workstation user;
a switch for coupling said workstation to one or more remote servers, the workstation taking control of at least one of the remote servers when logged on the system via the received keyboard or cursor control commands; and
a RFID detection circuit coupled to said workstation for detecting RFID signals from a card associated with the authorized workstation user, the RFID signals being indicative of that authorized user'"'"'s accessibility to one or more of said remote servers, andthe system automatically logging a workstation into one of the remote servers when the authorized user'"'"'s card RFID signals are in the vicinity of the detection circuit and are detected by the detection circuit and the authorized workstation user enters keyboard or cursor control device command indicative of the authorized workstation user'"'"'s access and, wherein the system automatically logs a workstation off the remote server-when the authorized workstation user'"'"'s card RFID signals are no longer in the vicinity of the detection circuit despite the presence of keyboard or cursor control device commandswherein keyboard, mouse and video signals are transmitted to said workstation from at least one of said remote devices when said user has access to said workstation;
wherein the authorized user'"'"'s accessibility is periodically confirmed by detecting signals indicative of the authorized user'"'"'s presence after an initial login;
wherein said RFID signal includes a unique identification number.

Abstract
A secure switching system that utilizes radio frequency identification (RFID) technology to allow only authorized users to access a remote management or keyboard, video, mouse (KVM) switching system. The system includes a plurality of user workstations that allow a user to select, monitor, and operate remote devices using a local keyboard, video monitor, and cursor control device. Coupled to or integrated with the system is an RFID transceiver that detects the presence of RFID tags that are within range of communications. A user workstation is only operable if the RFID transceiver detects a valid RFID tag.

11. A secure, remote device management system comprising:
-
a remote management unit for coupling one or more user interface devices to one or more remote devices; and a radio frequency identification (RFID) transceiver coupled to said one or more user interface devices for detecting RFID signals, said signals indicative of an authorized user'"'"'s accessibility to said system, wherein the one or more user interface devices takes control of the one of more remote devices when logged on the system, the user interface device being logged on the system when RFID signals are detected and the user enters information via the user interface device indicative of the user'"'"'s access, and the authorized user interface device being logged off the system when the authorized user'"'"'s RFID signals are no longer detected within a pre-defined range of the RFID transceiver despite the presence of a user input signal to the user interface device wherein keyboard, mouse and video signals are transmitted to at least one said user interface device from at least one of said remote devices when said user has access to said at least one said user interface device; wherein the authorized user'"'"'s accessibility is periodically confirmed by detecting signals indicative of the authorized user'"'"'s presence after an initial login; wherein said RFID transceiver communicates with an RFID transponder within the pre-defined range; and wherein said transponder transmits radio frequency signals containing a unique identification number. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A switching system comprising:
-
a workstation including a keyboard, a video monitor and a cursor control device; a switch for coupling said workstation to one or more remote devices; a radio frequency identification (RFID) transponder; and a radio frequency identification (RFID) transceiver, wherein said transceiver communicates with said workstation to verify an authorized user, further wherein the workstation is logged on the system and takes control of the one or more remote devices when the authorized user is verified and the workstation is logged off the system and denied access to the one or more remote devices when the transceiver does not detect the authorized user'"'"'s RFID signals within a pre-defined range of the transponder despite workstation user input signals to the keyboard or cursor control device; wherein keyboard, mouse and video signals are transmitted to said workstation from at least one of said remote devices when said user has access to said workstation; and wherein the authorized user'"'"'s accessibility is periodically confirmed by detecting signals from said transponder in response to activation signals from said transceiver after an initial login; wherein said transceiver sends activation signals; wherein said transponder receives said activation signals from said transceiver when said transponder and said transceiver are within the pre-defined range; wherein said transponder transmits radio frequency signals to said transceiver within the same frequency range as said activation signals from said transceiver; wherein said transceiver receives said radio frequency signals from said transponder; and wherein said radio frequency signals contain a unique identification number. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27)
