Speaking of which, there was
recently on how people aren't learning cursive writing anymore and
this makes (physical) signature verification more difficult. My signature is
a semi-readable cursive "Jerome Baum" (read: "Jer~~~ B~~~" ;) ) so I should
be safe, but I'm wondering how secure it actually is? Anybody know a good
article on physical signature security? I know the analyses are all about
writing speed and pressure but it would be good to see this "dumbed down"
for casual reading.
