Microsoft donates PhotoDNA technology to make the Internet safer for kids

As a technology vendor and industry leader, we take very seriously the responsibility of helping make the Internet safer for everyone. For schools, Microsoft supports mandatory online safety education…which safety experts say is the top way to reduce the risks children face on the Internet…and we provide resources for public officials, teachers and others. Over the past 20 years, the volume of child pornography traded online has exploded. To help combat the problem, Microsoft Research partnered with Dartmouth to develop a new technology called PhotoDNA that will help fight it.
This week, Microsoft announced the donation of the PhotoDNA technology to the National Center for Missing & Exploited Children (NCMEC) to assist in finding and removing images of child sexual exploitation from the Internet. PhotoDNA helps calculate the distinct characteristics…the “DNA”…of a digital image in order to match it to others, helping online service providers and others to better identify and stop the distribution of known images of child sexual exploitation online. Together, Microsoft and NCMEC hope to raise awareness about the global problem of child sexual exploitation and activate a larger movement on a solution by providing some new ways for consumers, online service providers, policymakers and others to get involved.
We hope this will have a tremendous impact both in the United States and around the world. The technology is currently based on images that NCMEC has identified from their CyberTipline and their role as a clearinghouse for U.S. service providers to report such images…so while many of the images are from cases in the U.S., some may be from other countries as well. Also, we anticipate that any implementation of PhotoDNA in online services from Microsoft or other service providers would likely apply wherever those services are available around the world.
