Abstract
Visual data transmission by an air-gapped system, including: transmitting, by an air-gapped system comprising at least one first computing device, a visual encoding of data via a display; detecting, during capture of the visual encoding of the data by a second computing device via a camera, an error; generating, by the second computing device in response to the error, and alert; and retransmitting, in response to a user input to the air-gapped system, at least a portion of the visual encoding of the data via the display.
Claims20
A method of visual data transmission by an air-gapped system, the method comprising:
- generating, in response to an error detected during capture of a visual encoding of data by a second computing device via a camera, an alert by the second computing device, wherein the visual encoding of the data was transmitted via a display by an air-gapped system comprising at least one first computing device;
- and
- retransmitting, in response to a user input to the air-gapped system, at least a portion of the visual encoding of the data via the display.
A system for visual data transmission by an air-gapped system, comprising:
- an air-gapped system comprising:
- an input device;
- a display;
- and
- at least one first computing device configured perform first steps comprising:
- transmitting a visual encoding of data via the display;
- and
- retransmitting, in response to a user input to the input device, at least a portion of the visual encoding of data;
- and
- a second computing device comprising a camera, wherein the second computing device is configured to perform second steps comprising:
- detect, during capture of the visual encoding of the data via the camera, an error;
- and
- generate, in response to the error, an alert.
