There have been a couple plugins which try to address this question: Chameleon (https://github.com/ghostwords/chameleon), which is still in early stages, and FireGloves (https://fingerprint.pet-portal.eu/?menu=6), which was built by a research group (not sure it's still supported).

Also a great paper on this topic: http://research.microsoft.com/pubs/209989/tr1.pdf
