Authorities post his face publicly and receive a torrent of replies

A man suspected of sexually abusing children was publicly unmasked last Monday when Interpol successfully unscrambled images of his face. Crops of the scrambled and unscrambled images were posted to Interpol’s website, along with a public plea for help, as all police efforts at identifying him thus far have failed.
 
Working from the original images found on the internet, specialists from the Bundeskriminalamt, or Germany’s Federal Criminal Police Office were able to successfully reverse what appears to be Photoshop’s twirl distortion tool, using unspecified methods. “Techniques are always developing. What is impossible today is possible tomorrow,” said Anders Persson, the Swedish police officer in charge of overseeing Interpol’s child abuse image database.
 
The images, which were taken in Cambodia and Vietnam sometime during 2002 and 2003, have been making the rounds around the internet underground in a series of about 200 images depicting the abuse of 12 young boys, whose ages range from six to the early teens.
 
Persson was initially hesitant to release the photos publicly, as it would signal to criminals that police forces were capable of unblurring images. Outweighing that consideration, however, was his interest in protecting other children from predators. “It was a long discussion,” said Persson, “… we have exhausted all possibilities within [the] police to find this man … this was the last step.”
 
For decades the scrambling of images – usually with a mosaic or blur filter – has been common practice in protecting private information and safeguarding the identities of publicly pictured individuals. In an article titled “Why Blurring Sensitive Information is a Bad Idea,” Dheera Venkatraman outlines the method for a possible attack against scrambled images using a technique similar to rainbow table attacks that are used against one-way scrambled hashes frequently used for storing passwords. His conclusion: “don’t blur your images!”
 
Interpol received over 200 messages in the first 12 hours after releasing images of the man’s face. “We have a lot of responses and they are coming from all over the world,” said Persson, with some messages including detailed information that includes names and addresses.

Huh, and here I thought the lesson was "Don't be a child molesting piece of human waste".

Who are you calling a child molester?

Unless it's the dude whose face got unswirled, you need to STFU.

And for the love of god, please leave FR flame wars at FR. Nobody else gives a damn what you do over there.

Seriously, what's with these people? Obviously they didn't get my point, which was this is the one and only time they'll be able to use a modified photo to catch a criminal. I figured intelligent people were the sort who read dailytech, but apparently I was mistaken, and should have spelled it out for them.

But you just did what I predicted you would; come up with a explanation on your poor choice of sarcasim and try to blame others for their "misinterpetation."

Its not a personal attack on you, but there are some things in life that are off limits when it comes to sarcasm... one of them is child molestation.

We all know that your statement is not true "Obviously they didn't get my point, which was this is the one and only time they'll be able to use a modified photo to catch a criminal." The good guys are getting better at every day at catching the child molesters. Even the good guys are catching the assumed good guys in that case of the Federal Prosecutor who just off'd himself.

I feel his sarcasm was not pointed toward child molestation directly. It was pointed more towards dumb criminals who post pics of themselves doing illegal activities(he generalized this situation). Besides I do not consider this article really that great overall for law enforcement. You are telling me Interpool just now thought about this??? Makes me go "WTF Mate!" Seriously lets drop this bs. Bad guy caught being stupid, cheers!

Looks like mcmilljb got it right:

You said:

It doesn't seem that mcmilljb misinterpreted my point.

Well, since naturally the only person on the internet using the alias Polynikes is me, everything bad said by "Polynikes" on any forum or website must, therefore, be me.

When you assume, you make and ass out of you. (Not me, though.)
