Microsoft is unveiling a new technology Wednesday aimed at tracking and removing every trace of child pornography from the Internet.

The system, called Photo DNA was developed by Microsoft and Dartmouth College.

The system converts known images of child pornography into a mathematical pattern, which can then be used to identify and remove the images from other networks.

The developers say Photo DNA can track the images to every online location they move to after their original posting.
