A tool to explore optical data transmissions and covert channels

OpticSpy is Now Funding

The OpticSpy campaign is now live!

Here’s a short video demo of the original motivation behind creating the OpticSpy. I had been looking into different types of covert channels and the method of using an LED to send data really appealed to me. There’s some great prior art in this area (see the Inspiration section of the campaign page), but descriptions of how a user could build their own receivers were lacking. Hence my experiments.

Feel free to share this project with anyone you know who might enjoy learning about optoelectronics, optical data transmissions, and/or covert channels. Thanks!
