In 2009, Microsoft - working with Dartmouth College - developed PhotoDNA, a technology that aids in searching, finding, and removing some of the worst images of child sexual exploitations available on the internet. “PhotoDNA is a substitute for the eyeballs that saw photos going through the photoshop printing machines in the 70s”, explained Harmon.
“Back then, child sexual exploitation still went on, but a lack of technology acted as a disabler for criminals. But now, it’s easier for them. Technology, including digital photography and the internet, make it easier for paedophiles – they can also share their experiences and photographs online with likeminded criminals”, Harmon said.
Microsoft donated the PhotoDNA technology to the US National Center for Missing & Exploited Children (NCMEC), which established a PhotoDNA-based programme for online service providers to help disrupt the spread of child pornography online.
Microsoft and NCMEC implemented a gradual rollout of PhotoDNA on Bing, SkyDrive and Hotmail services. In early 2011, Facebook joined Microsoft in sublicensing the technology for use on its network. “The idea is for everyone to get on board”, Harmon explained.
“If we use technology the right way, we can find these photos just like we did in the 1970s photo shops. We can win”, he concluded.
