20110145451 | ISOLATED MULTI-NETWORK COMPUTER SYSTEM AND APPARATUS - The present invention presents apparatuses and systems for operating multiple computers from a single console using a secured KVM device, while preventing information leakage between the computers. The system comprises several hosts connected through a secured KVM device to keyboard and mouse and one or more user displays. Secured KVM enables standard bi-directional communication between Secured KVM and user keyboard and mouse and between hosts peripheral ports and Secured KVM. Secured KVM physically enforces unidirectional data flow from attached keyboard and mouse to attached hosts peripheral ports to avoid potential leakages between hosts. | 06-16-2011 |
20130067534 | COMPUTER MOTHERBOARD HAVING PERIPHERAL SECURITY FUNCTIONS - A secure motherboard for a computer, wherein each user accessible peripheral port is protected by hardware based peripheral protection circuitry soldered to the motherboard. The protection circuitry provides security functions decreasing the vulnerability of the computer to data theft. User input ports such as keyboard and mouse peripheral ports are coupled to the computer through a security function that enforce unidirectional data flow only from the user input devices to the computer. Display port uses a security function which isolates the EDID in the display from the computer. Authentication device such as smart card reader is coupled to the computer via a port having a security function which enumerates the authentication device before coupling it to the computer. | 03-14-2013 |
20130219525 | SECURE AUDIO PERIPHERAL DEVICE - A secure audio peripheral device, coupled to a computer, capable of enabling a user to use audio devices such as a microphone, speakers or headset when the device is in operational state, while giving to the user a clear visual indication that the audio devices are enabled. The device simultaneously disables the microphone; and turns off the visual indication when the device is in secure state. The operational state is activated by the user by pressing a momentary push-button switch. A timer resets the device to a secure state after a short preset time. The device has anti-tempering functionality and becomes permanently disabled if tempered with. Optionally the device is coupled to the computer via a USB port that powers a USB CODEC chip and a LED used as the visual indicator. | 08-22-2013 |
20130222609 | SECURE VIDEO CAMERA DEVICE - A secure video camera device for reducing the risk of visual and audio eavesdropping has a video camera and an electromechanical shutter behind a transparent cover in a secured enclosure. The shutter optically obscures the camera lens when the device is in secure state. A visual indicator indicates when the device is in operational state. A switch controllable by the user, select the state of the device by concurrently disabling the camera turning off the visual indicator in a secure state; and setting said device in an operational state by concurrently enabling the camera and turning on said lighted indicator. The device has a built in, or auxiliary microphone, and audio outputs which are disabled in secure state of the device. The device is tempered proof by an anti-tempering circuitry. | 08-29-2013 |
20140015673 | SECURE PERIPHERAL CONNECTING DEVICE - A secure peripheral device, coupled to a computer, capable of enabling a user to use a peripheral device such as a microphone, speakers, headset or video camera when the device is in operational state, while giving to the user a clear visual indication that the device is enabled. The device simultaneously disables the user peripheral device; and turns off the visual indication when the secure peripheral device is in secure state. The operational state is activated by the user by pressing a momentary push-button switch. A timer resets the device to a secure state after a short preset time. The device has anti-tempering functionality and becomes permanently disabled if tempered with. Optionally the device is coupled to the computer via a USB port that powers it. | 01-16-2014 |
20140019652 | SECURE KM SWITCH - A system enabling a computer user to securely share a single set of keyboard and mouse (KM) among multiple isolated computers. The system enables one set of peripheral devices to independently interact with multiple coupled isolated computers through mouse position analysis on a virtual display area corresponding to multiple physical user displays of the particular installation. The system may be used to enable computer user having multiple isolated computers each with one or more coupled display to automatically switch a single set of keyboard mouse and other peripheral devices between the different computers. As isolated computers may have different security levels, the method and apparatus of the present invention prevents and potential data leakages between computers and coupled networks. | 01-16-2014 |
20140053256 | USER AUTHENTICATION DEVICE HAVING MULTIPLE ISOLATED HOST INTERFACES - Devices and methods provide for enabling a user to use a single user authentication device such as smart-card reader, such that the user is capable of securely interfacing with two or more isolated computers and enabling the user to authenticate and remain authenticated at multiple computers at the same time. Once the user removes the smart-card from the smart-card reader, the authentication session on all coupled computers is terminated at once. The user authentication device comprises: an authentication module connected via a channel selection switch to one of a plurality of channels, each interfacing with a respective coupled computer. | 02-20-2014 |
20140075535 | METHOD AND APPARATUS FOR STREAMING VIDEO SECURITY - A streaming video security device is provided that comprises an input LAN interface, at least one streaming video decoder, an output LAN interface, at least one streaming video encoder coupled at one side to said LAN interface for streaming video output and coupled at the other side to a raw video display-compatible output interface; and unidirectional data flow element coupled at the transmitting side to the streaming video decoder through the raw video display-compatible output interface and coupled at the receiving side to one or more video encoder through the raw video display-compatible input interface. | 03-13-2014 |
20140244880 | SINGLE OPTICAL FIBER KVM EXTENDER - Single Optical Fiber KVM (Keyboard Video Mouse) systems are provided that comprises of two subsystems: an electro-optical transmitter subsystem and an electro-optical receiver subsystem. The single optical fiber KVM is configured to support all required bi-directional communications. | 08-28-2014 |
20140289433 | ISOLATED MULTI-NETWORK COMPUTER SYSTEM AND APPARATUS - The present invention presents apparatuses and systems for operating multiple computers from a single keyboard and a single mouse and view composite videos generated from video output of the multiple computers on a single display, while preventing any possible information leakage between the computers. Keyboard and mouse commands detected by a host controller are used to control a video processor and a peripheral switch. The peripheral switch directs keyboard and mouse signals to one selected host and at the same time, the video processor creates an active display window showing video information from the selected host. Physical unidirectional isolators in the video, keyboard and mouse channels prevent any potential data leakages between hosts. | 09-25-2014 |
20150020189 | ELECTRO-MECHANIC USB LOCKING DEVICE - USB ports present risk of data leak from computers. The invention provides an electromechanical USB port protection device capable of mechanically block unused USB port, thus preventing the connection of any USB device to that port.
