Microdots have a long and storied history in the transfer of information over obscured channels. In the same family of invisible inks and stenganography, microdots were the OG side channel attack and were used to great effect throughout the cold war.
But the advent of more modern methods of data storage and transfer have rendered film microdots obsolete. In this talk, I discuss the technical concepts behind how I made the microdot, and a modern twist on microdot methodology to bridge the gap between analog and digital microdot creation and use.
