Google Helps Police With Child Porn WebCrawler (siliconbeat.com)

The San Jose Mercury News is reporting that the Internet Watch Foundation, "an organization that works with police worldwide to remove images of child sexual abuse from the Internet, has credited Google with helping it develop a 'Web crawler' that finds child pornography." The pilot project makes it easier to identify and remove every copy of specific images online, and the group says "We look forward to the next phase of the Googler in Residence project in 2016." Last year Google also had an engineer working directly with the foundation, and the group's annual report says "This was just one part of the engineering support Google gave us in 2015." [PDF] Their report adds that the new technology "should block thousands of their illegal images from being viewed on the Internet."

      Ironically, the possession laws are the sole reason why it isn't millions or billions. IMO, if you really want to get tough on harm to children, it has to be legal for people to A. submit photos that they think might be child porn, so that authorities can investigate them, and B. submit photos and metadata to a server to determine whether it is known child porn, with a guarantee that nobody will try to track you down and send you to jail or confiscate your equipment merely for checking a photo that you have questions about (or even a million photos that you have questions about).

      But to make that possible, short of hiding it in some sort of onion routing nightmare, the existing possession law likely would have to be either drastically scaled back or eliminated. Why? Suppose somebody posts child porn on an Internet forum that I own/maintain. There are basically three likely outcomes:

      • A user flags it for review. A moderator looks at it and decides to delete it. Odds are, nothing bad happens.
      • A user flags it for review. A moderator contacts law enforcement for advice. The server is now part of an active investigation, and gets taken offline for forensics. In the best-case scenario, I get my hardware back in a couple of months. In the worst-case scenario, I lose the hardware, my backups, and the domain name through civil forfeiture.
      • I add software to scan the file and ask some server whether it is child porn. That request is logged. Law enforcement now knows that this image is on the server, and begins digging through other parts of the server. They find some image that wasn't in the database yet when it was originally submitted, but that is, in fact, child porn. Again, I lose the site for at least a couple of months, and maybe forever, thanks to civil forfeiture laws.

      Each of those scenarios other than the first one is basically a death sentence for a website. So right now, with the law as written, the safest thing a site owner can do is to avoid looking for child porn, and if they discover child porn inadvertently, destroy all evidence that it was ever there. This is the polar opposite of the behavior that the law should be encouraging, and the sole reason for that is that possession laws invariably cause more harm than good, no matter how heinous the thing you're trying to ban.

      I wonder exactly what they use for matching. It's not like most pictures of a kid in a swimsuit are CP,

      It is probably as simple as an MD5 sum, but could include simple image matching. From TFA:

      The project, which a foundation spokeswoman described as a pilot, facilitates removal of all circulating copies of particular abuse images.

      In other words, they have an image that is already known to be CP, and they're looking for other places where it is available on the web. It's not a hard problem to do a checksum and then visually examine anything that matches. It won't catch your "picture of your kid in a swimsuit" or "mom in the bathtub with baby Susie" unless you've been distributing it as CP already.

      You would be surprised what is considered CP sometimes.

      I'd imagine that it has to be a bit more complicated than that though, otherwise a single pixel of difference is all that breaks the checksum. I suppose it might be "reduce the image to a simple form" (reduced color depth, size, etc) and then checksum, but that would consume an awful lot of computing resources.

      A single pixel change is unlikely, but that's why I also said it probably included some image matching. There are simple ways of comparing images that would give good results.

    A 25 year old woman is an adult and cartoons are only vaguely similar to real people (and indeed are not real at all). What the hell are you talking about?

    That in Australia, a 25 year old woman can make what Australia defines as "child porn".

    And in the US, a person has been convicted of possessing "child porn" from his collections of cartoons (Japanese Manga that contained some tentacle scenes).

    Child porn prosecutions that don't involve children at all. That's why they aren't the same issue.

    Not being able to distribute child porn is now "oppression"? Is it also oppression that you aren't allowed to rape and murder?

    Is a picture of a rape illegal? No (unless child porn). Is a picture of a murder illegal? No. Those are separate legal issues. So why is it that the depiction of the crime is linked to the crime for one and only one crime?

  22. Hiding evidence of a crime by FeelGood314 · · Score: 1

    My biggest issue with groups or governments doing this is they are hiding evidence of a crime. This allows groups to sound outraged, pretend they are doing something about a problem and claim that they have reduced CP while safely ignoring that fact that they have done nothing to prevent child abuse and have quite possible made it worse.

    Why does this sound like the same approach used for issues like prostitution vs rape and human trafficking or drug use vs mental health?

    So my daughter might be taking nude selfies of herself on her phone, which Google flags as child porn. But its not a pedo, its a selfie. So the engineers should carefully review those selfies, decide the phone belongs to a child, and the pictures are likely her own.

    Except it is pedo, she's guilty of manufacturing CP, distributing CP if it's been sent to her BF, and exploitation of a minor (herself).. and the authorities should handle it since criminal charges will teach her not to ruin her life, by ruining her life. At least that's what some police officers and prosecutors think, and judges don't seem to mind either. It's not theoretical either, kids have actually been hit with those charges, most commonly for sharing, but for possessing too-- that's right, a prosecutor in NC actually had the gall to charge a 17 year old and his gf with exploitation of a minor for possessing naked pictures of themselves (distinct from the various other charges for sending and having their partners pics), in just one example of this obscene abuse of the law. If you think that's crazy, the insanity didn't even stop there: the boy was charged as an adult!
    This country has completely lost its shit over teenage sexuality since it's been combined with technology. Probably because childhood has been extended so far that people don't recognize the difference between 17 and 7, so are equally freaked out by sex with the two ages.
