This has been discussed several times over, but just for your sake...Lucas left that speculation open. So, either Plagueis is Anakin's 'father,' or the Force alone was his father, or Plagueis did not actually know the trick and Palpatine just said it to bait Anakin.
I prefer to think that it was the Force alone and that Plagueis didn't actually know the trick. We'll see at some point in the future, when we know more of Plagueis.
