TEMPEST aura
TEMPEST aura is a device...
Bengt Sjölén
TEMPEST aura is a device for mapping the electromagnetic emanations of any electronic device. Any transition of an electric signal between on and off, between current and no current, will also transmit a burst of electromagnetic energy that can be intercepted by a receiver and in this way all of our information processing devices also leaks the information they process for anyone to eavesdrop. TEMPEST aura takes images, much like a scanner, of an electronic device you put on it’s surface showing the aura of information and energy emanating from the device.
