Ooh, I never considered the rolling shutter effect.
That's amazing. The paper is called "Video-Based Cryptanalysis: Extracting Cryptographic Keys from Video Footage of a Device’s Power LED" [0].
Edit: Also, worth viewing the video [1] on the author's post [2].

- fisian 3y agoRolling shutter is quite nice and used in different scenarios to increase framerate. For example to extract sound from just a camera [1]. Additionally, while not directly related to the rolling shutter effect [2] uses a technique to increase the framerate of the Raspi Camera by 10x or more, but reducing image resolution.
