Wartime intellegence included learning the "hand" of various operaters to trace movements, to distinguish false transmissions, and to try to fake transmissions.

Former submarine sonar operator on youtube is always talking about when they were following a target around, they eventually learned the differences between the drivers and such on each watch just by the differences in sound they'd hear.

It's amazing the amount of information trained people can glean out of enough noise.

Now, imagine what a computer can do. Provided that they have enough text, they can be pretty sure that you and that other person on another site is pretty much the same one, just by the style and typo you make.

Yeah, but can they see why kids love the taste of Cinnamon Toast Crunch?

There was a test website that authenticated you based on the way you type your username and password. It appears to be offline though.

It's called the "fist" not the hand. Source I still use Morse Code as a Ham Radio Operator.

Do mid 20th century British writers use the same word?

I don't know. But I've been a Ham since I was a kid in 1982 and I know many hams that were licensed in the early 60's. I've always heard it was someone's "fist" that was unique. However most operators since the early 80's use what is known as a "keyer" and a set of paddles. One paddle make the dit (dot) and the other makes the Dah (dash). The keyer makes perfect spacing for each letter and therefore makes you sound less unique but better and easier to copy. Also using an electronic keyer allows you to send much faster (>60wpm in some cases) than a straight key like you see in old movies.
