Fortunately, for many of us, signing for packages is probably the only frequent use of our scrawl so hopefully the potential for fraud from this hack is lessened. I think a scarier prospect is that signature recognition may make it possible for someone to search for all the packages you've ever signed-for, regardless of the courier or location at which you accepted it. I'd be surprised if couriers weren't already doing this in collaboration with law enforcement.
