Pornographic images of children circulate on the Internet at an alarming rate. Since 2002, the National Center for Missing & Exploited Children (NCMEC) have reviewed and analyzed nearly 49 million photos and videos of child pornography--more than 13 million in 2010 alone--according to Ernie Allen, NCMEC president and CEO.
PhotoDNA is a technology developed by Microsoft that helps find and remove some of the “worst of the worst” images on the Internet. Microsoft donated the PhotoDNA technology to the NCMEC who developed a PhotoDNA-based program for Internet companies. Recently, Facebook announced that they would be using the service on their site.
