Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
