Microsoft Tackles the Child Pornography Problem
(New York imes)
The National Center for Missing and Exploited Children assists law-enforcement authorities by culling through 250,000 images a week, looking for illegal material, and sends daily alerts to 68 Internet service providers worldwide. It is difficult, labor-intensive work for all. But Microsoft is contributing new image-matching software, PhotoDNA, that promises to automate and streamline online child-pornography monitoring. The new software is the result of two years of collaboration by a team at Microsoft Research, led by Larry Zitnick, and a group at Dartmouth College. In test runs, PhotoDNA has processed images in less than five milliseconds each and accurately detected target images 98 percent of the time.
