Asking her out
Post pictures to Facebook, hiding messages in the low bits.
Assume her messages mean something See if they continue to make sense
Other Uses
Cheating at cards Cheating on spouses Planning a coup
She only knows that you're asking her out if she's asking you out
Revealing result
We want either both parties or neither to know the answer Otherwise, unfair and one party could embarrass
the other. But the protocol works by each side “speaking”
in turn Inherently one-sided
Reveal only one bit at a time Only twice as much work for one side as the other
Other Uses
Cheating at cards “Would you like me to slip you an ace?”
She only knows that you're asking her out if she's asking you out
(and vice versa)
