Microsoft is giving law enforcement PhotoDNA, a digital tool that sifts through massive amounts of online images to help identify instances of child pornography and rescue victims.
The software giant announced overnight that it, along with NetClean, a Swedish maker of technology to combat the spread of child porn, will give away the image-matching software to help law enforcement agencies detect new images of child abuse online. That then helps those agencies focus their efforts on tracking down abusers.
