Everyone remember Baron Ryoval's signet ring?

"An engineer has rigged up several devices that enable a touch
interface to respond to nuances such as pressure."
.....
"F. Signet Ring
Capacitive touch screens can also accept input from multiple
simultaneous touches. That's the basis of a low-level security feature
Knuepfel designed. He made rings that use conductive material to
create several electrical pathways from the user's fingers to the
screen. These pathways are arranged in a distinct pattern; software on
a tablet could look for a user's pattern before allowing access to
private content."
