And a video demo at:
"It is important to note that it is assumed that the victim is wearing the WAD on the wrist of the preferred hand used to interact with keyboards.
In fact, in our attack scenario it would be harder, if not impossible, for the attacker to infer keystrokes if the victim is right-handed but is wearing the
WAD on the left hand for example."
A WAD is any wearable arm band device.
I think I started it to be different when I was a teen and the habit just stuck.
Yes, for right-handed people. The opposite is true for left-handed people, and left-handed versions of watches.
>The LSTM model can also successfully classify signals with an accuracy of 19% when the dataset used for training and logging are originated from two different keypads.
Still scary to think how a motivated team could extend this though.
I wrote a bit on the topic. Unfortunately, not my finest writing in terms of clarity, but I think it touches something important.
