title: Algorithm to determine someones age given only a drivers license number?
body: <p>I have been debating doing some work on a site which might be age restricted, one of the things have thought about is a hassle free way to confirm a user's age. I recently heard that the site with the movie trailer for the film ted asks people to enter their name and drivers license number to confirm their age. <a href="http://www.tedisreal.com/" rel="nofollow">http://www.tedisreal.com/</a> Are they using an algorithm or is there an open governmental api for this kind of data? I have done some searching on this topic and all I can find is a program written in perl from 2004 which no longer appears to be supported. </p>
  
  <p>Any knowledge about this topic would be appreciated!</p>
