             SENSITIVE INFORMATION


                                PAUL OHM*


                                ABSTRACT
     Almost  every information privacy law provides  special protection for
certain  categories of  sensitive information,  such as  health, sex, or
financial  information. Even   though  this approach   is widespread,  the
concept  of sensitive information  is woefully undertheorized.  What  is it
about  these categories that deserves special protection? This Article offers
an  extended examination  of this question. It surveys dozens of laws and
regulations to develop a multi-factor test for sensitivity.
     From   this survey, the Article concludes that sensitive information is
connected  to privacy harms  affecting individuals. Consistent with this, at
least for the case  of privacy in large databases,  it recommends   a new
threat modeling  approach   to assessing the risk of harm in privacy law,
borrowing  from the computer  security literature. Applying this approach, it
concludes  that we  should create new  laws  recognizing the sensitivity of
currently unprotected forms of information-most   importantly, geolocation
and  some  forms  of  metadata-because they present significant risk of
privacy harm.
