Technology to filter photos in Web searches may help the Justice Department curb online trafficking in child pornography. The department has thus far focused its efforts on prosecution, non prevention.

The Justice Department says there’s been an “explosion” in the trafficking of child pornography, and information technology’s pledged to step up investigations of people who download the illegal images.

But the government has inappreciably been neglecting the trouble: Since 2000, the number of federal prosecutions has virtually tripled. This has caused some people to ask whether more couldn’t be washed to prevent people from downloading the illegal images to begin with.

Microsoft is voluntarily developing technology that makes it harder to stumble upon child pornography on Internet searches, merely officials question whether or non it will actually curb corruption of the children used in the photos.

Serving Fourth dimension

In September 2004, a family unit in Northern California became the subject of a child pornography investigation, prompting a visit from the FBI.

“I become a call from my wife, she’due south crying and upset, and and then I went home, and there were several agents going through my house, who stated that in that location was … child porn on one of the computers,” says Dave, who asked to have his terminal proper noun withheld to prevent jeopardizing his job.

In this instance, the images were on a computer used by his 20-year-old son. His son is now in prison, serving a 3-twelvemonth judgement for one count of possessing child pornography. Dave notwithstanding tin’t get over how much damage was done by some computer files.

“You have a young kid that has no criminal history … is not a pedophile, is non a child molester, and he’south going to exist labeled as a sexual activity offender and have to register as such every twelvemonth, on his altogether, for the residuum of his life,” he says.

Of form, these aren’t merely any computer files. Jeff Fischbach, a forensic annotator who works with this kind of material, says he’south seen what happens when these images are shown to juries.

“You tin watch the expressions change. I saw ane admirer in the front row of the jury, I think information technology was number three, and I saw him lurch forwards toward the defendant,” Fischbach says.

Defendants most never risk going to trial; lawyers ordinarily recommend they accept a plea bargain. It’s Fischbach’s task to analyze the hard drives in these cases, and when he does, he follows strict protocols — as if the hard drives contained plutonium.

“It is handled similar it’s radioactive,” Fischbach says.

Filtering The Photos

He keeps the drives in special locked boxes, and never connects them to the Net or other computers, for fright of cantankerous-contamination. He knows the legal jeopardy that tin be caused by fifty-fifty one stray thumbnail image. And yet, he says, the very same files can be establish on the open Net quite hands.

“Right now, anybody is just ane search term and a click on Google away from about of the same files that I take seen as part of my work,” he says.

Fischbach believes the easy-to-notice images are a kind of public hazard.

He worked for i defendant who went to prison because of one nighttime of ill-advised Web surfing. The easy-to-find images are likewise tempting weapons in messy custody battles and divorces — he’south convinced that in some of the cases he’south worked on, i spouse has been framed by some other. All of this makes Fischbach wonder why more isn’t washed to cake some of the more than obvious sources of these “radioactive” files.

“It’s the same affair equally any other public nuisance. Part of the regime’south job is not simply to become out at that place and stop people from doing bad things, but to stop good people from having to fall victim to that,” he says.

It’due south probably non constitutional for the authorities to block offending Web sites outright, but Fischbach says Internet service providers and search engines could volunteer to filter the images that reach their customers, just every bit e-mail providers filter out known viruses.

He’s been suggesting this idea for years, and at present somebody is trying it.

John Scarrow is general manager for Prophylactic Services at Microsoft, which is developing technology chosen PhotoDNA.

In a contempo demonstration at the Microsoft campus in Redmond, Wash., Scarrow uploaded a dummy child porn photograph to Microsoft’s cloud computing service chosen SkyDrive. The numeric value of that photo — something called a “hash value” — is checked confronting a master list of known child porn photos maintained by the National Center for Missing and Exploited Children. If the photograph matches one of those, the account is disabled and an error message appears.

Microsoft is using a more flexible version of traditional hash values, so it can ID an image even if it’s been cropped or resized. This flexibility takes some heavy math — and that means information technology can’t exist used to filter the whole Internet because it would accept likewise much computing power.

But Scarrow says filtering everything was never the point.

“Somebody that’due south smart enough that really wants to traffic in the material will figure out how to circumvent these. But … the person that is getting a hold of information technology because it’s pretty like shooting fish in a barrel to get a agree of, you know, is just looking effectually, whatever … we believe, this will take a pretty substantial bear upon on them,” he says.

The filtering organization is already running on the Bing search engine — if someone’due south search finds a site with known child pornography, those links are suppressed.

‘Part Of An Reply’

Microsoft is planning to aggrandize the filter to its other online services, and it’due south offer to share PhotoDNA with other online portals for gratuitous. And the project has the tentative support of the Justice Section.

Drew Oosterbaan, who runs the Criminal Division’s Child Exploitation and Obscenity Section, says the filtering isn’t the last solution.

“I think it’s off-white to say that it may be part of an answer,” he says.

Oosterbaan says file-blocking could become, in his words, “another front in the battle,” just he says there could as well be unforeseen consequences. One possibility, he says, is that the filtering could piece of work too well.

If child pornography became besides hard to find, he says, it might create demand for new images and cause more children to exist driveling.

“That’south why this is a very, very challenging expanse of law enforcement, where, in the by 10 years, I’ve never found any real simple solutions,” Oosterbaan says.

For now, filtering images with PhotoDNA is a airplane pilot project — and it’s purely voluntary. One affair its developers insist on is that they don’t want to run across it evolve into a filtering system that’south mandated past the government.
