A partnership between Microsoft, Facebook, and the National Center for Missing and Exploited Children
Today marks a significant milestone in the ongoing fight against the abuse of Internet technology for the heinous sexual victimization of the most innocent in our society. As you may have read in the New York Times, Facebook is joining Microsoft in the National Center for Missing and Exploited Children’s PhotoDNA program to combat child pornography. NCMEC’s program, using image-matching technology created by Microsoft Research in collaboration with Dartmouth College, gives online service providers an effective tool to take more proactive action to stop the distribution of known images of child sexual abuse online.
In partnership with NCMEC, Dartmouth College, Microsoft Research, Windows Live, Bing and many others, Microsoft’s Digital Crimes Unit has long worked to advance innovations and strong partnerships to combat child exploitation. In 2009, Microsoft, working with digital imaging expert Dr. Hany Farid of Dartmouth College, developed PhotoDNA and freely licensed it to NCMEC for use in a program to disrupt the online distribution of the worst known images of child pornography known to NCMEC.
Microsoft began implementing PhotoDNA technology in Bing and SkyDrive, including images posted to SkyDrive through Hotmail, in a thoughtful and gradual process in order to assess the capabilities of the technology and we are seeing strong results. PhotoDNA identified horrific images on our services that we would have never found otherwise. To date, we have evaluated more than two billion images on our services using the PhotoDNA signatures provided by NCMEC, leading to the identification of more than 1,000 matches on SkyDrive and 1,500 matches through Bing’s image search indexing.
