cure identity theft
with the advent of informational sharing increasing at an exponential rate both legally _and_ illegally, i see the only way to stop identity theft and similar related crimes by not simply hiding information, but rather the opposite, make information even easier to access.
the idea here, is to make public information so publicly available to anyone on earth that people's whereabouts on earth can be known to be unique.
if a location of a particular person is unique at all times, identifying oneself would not only be near-impossible to replicate falsely, but also fast, easy, and efficient.
what other benefits/problems are there related to complete public awareness?
