Usually, when hands are wet the phone won't accept interaction. I would suggest if you tap rapidly, say the home button or maybe a link the phone would recognise that these touches are infact you.

Then surely the answer is, dry your hands.
Your suggestion of double or tripple tapping would be a real security issue.
