Microsoft, with the help of imaging experts at Dartmouth College, created PhotoDNA, an image hashing technology that helps to identify and combat the distribution of graphic child pornography online. PhotoDNA has been used by Facebook and Microsoft’s Bing, SkyDrive, and Hotmail services to combat the online redistribution of the worst images of child pornography known to NCMEC. It has also been made available to law enforcement at no cost, supported by a partnership with NetClean.
