Stop cellphone theft?

Excerpts from http://www.newscientist.com/article.ns?id=dn8161


Researchers in Finland have developed a prototype of a cell phone that
uses motion sensors to record a user's walking pattern of movement, or
gait. The device periodically checks to see that it is still in the
possession of its legitimate owner, by measuring the current stride
and comparing it against that stored in its memory. If the phone
suspects it has fallen into the wrong hands, it will prompt the user
for a password.
