I've heard of that idea before. It wouldn't work for many reasons, the main being "cache invalidation." i.e. it becomes obsolete as soon as somebody has another sexual partner. And at that point, you're trusting users to just update it.
That doesn't even mention the privacy issues involved.
Yes, because I'm sure tons of people will line up to have their fingerprint/eye pattern associated with contraception and their last potential hookup in a 3rd party database. What could go wrong?

Sadly, I am also sure of this.
maybe we can make a website where we "verify" if people are trustworthy before drunken hookups.
tryna take home a dude at the bar? just verifyhim
we can even call it verifyhim. scan his fingerprint on your iphone and/or use your cameraphone to scan his eyes to verify if he was using the man pill last time he hooked up.
