UK Authorities Launching Massive Child Abuse Database 150

mrspoonsi sends news that "Data taken from tens of millions of child abuse photos and videos will shortly be used as part of a new police system to aid investigations into suspected pedophiles across the UK." The Child Abuse Image Database (CAID) will be available to authorities starting December 11th. It's been populated with data seized in earlier investigations. The database assigns a hash to each photograph, so when a new drive full of illegal images is confiscated, it can immediately be plugged in and quickly scanned to see if there are any matches. It will also catalog GPS coordinates from Exif data.

The purpose of CAID is to eliminate the duplication of effort when investigating these photos. Often when storage drives are seized, they contain thousands or millions of images, and dozens of different police departments could end up unknowingly investigating the same victims. Law enforcement liaison officer Johann Hofmann said, "We're looking at 70, 80, up to 90% work load reduction. We're seeing investigations being reduced from months to days."

    For the protection of the children you see, they should have a huge government database of file hashes they deem illegal. This year it's for the children, next year it's for enemy's of the state. You wait, you will see...

    Power corrupts; absolute power corrupts absolutely.

      Just as well its not France, they would want a database of enemies of the language.

      I used to do this work, I worked for a digital forensics contractor for a number of years in the UK. I had to get out because I felt like I was beginning to be a character in a George Orwell novel, especially when the "extreme images" legislation started to be mooted. I created a central hash database for our lab using some software out of an Ontario police agency called C4P, it was most useful for eliminating what we called "ignorable" images but I was shocked at the images some of my fellow analysts deeme

All the software tools in the world won't help if you turn them away at the station or refuse to do any of the work for fear of hurting feelings. Spend less on computers and more on prosecutions for those cops who let those girls suffer.

            There is a win-win situation. Target the perps, and tell the social-justice crowd to shove it up their pie hole along with the muslims that will come screaming out of the woodwork crying that it's racist. Not rocket surgery, not by a long shot. The problem isn't so much that it happened, but that it was allowed to happen. And that it's happened more then once. Europe has a serious problem with problems like this, so does their media.

              The muslim angle is just a distraction. The real problem is that when the girls or people around them did complain the police did nothing. They seemed to feel that because many of the girls were from poor or troubled backgrounds that they were probably consenting or wouldn't be convincing as witnesses in court anyway, so just allowed the abuse to continue.

The actual number of victims that have been confirmed is ... seven ... by five different perpetrators. The scandal has a close resemblance to both the Salem witch trials, and the American satanic ritual abuse (SRA) scandal [wikipedia.org] of the 1980s. SRA was once estimated to involve "millions" of victims, but in hindsight, the number of victims is now believed to have been zero. The Rotherham sc

          The number seven comes from what the Crown Prosecution Service have chosen to prosecute and got convictions for. They have many more on file. Some will be where the victim is unwilling to give evidence in court, or the CPS believe would not make a good witness on the stand. The job of the CPS is to make sure the bastards rot in jail, this does not necessarily correspond to prosecuting all possible cases of abuse.

          It is quite clear that the abuse was wide spread in Rotherham and worse was not confined to Rotherham either. There have also been very similar cases in Derby, Oxford, Bristol and Telford. All involving gangs of majority Muslim background perpetrators sexually abusing and trafficking mainly white girls.

          Yeah, that was also my take on it, just from the bit of reading I did on it. Kept seeing that "thousands" claim but absolutely no evidence for anything even close to that number. Thanks for the confirmation.

      The cops are a symptom, not the cause of ills in our society. We have to fix what's broken in our basic social systems before this problem is going to go away. All the cops can hope to do is catch offenders after the fact.

    I have a small problem with the phrasing "suspected pedophile". It propagates the view that being a pedophile is a crime, not that child abuse is a crime.

    Would they have a database of people "suspected of having high testosterone levels" too?

    The risk of innocents being caught in a dragnet is, in my opinion, not justified by the heinousness of abuse. A pedophile (or a father, a much higher risk group) who is innocent is just as innocent as a child. And someone who is guilty is just as guilty whether they're a pedophile or not.

    A child, by the way, is a suspected future drug criminal with a quite high risk. Better register all children as suspects too.

    Anyhow, there's a technical solution to every technical problem. In this case, a viewer that changes one pixel subtly every time an image is viewed would make hashes like this useless.

    • by Anonymous Coward

      I'm more worried about the potential abuse this could cause. Someone takes a child abuse photo, attaches some EXIF data to it pointing to a person they don't like, then uploads it anonymously somewhere. Pretty soon the police are beating someone's door down, stealing all of their computers, and otherwise making their life a living hell.

        The problem is the belief that hashes or other fingerprinting techniques is a silver bullet, infallible. It isn't. You need a human to actually look at the pictures, and until the politicians who control the police understands that, redirecting resources this way is only going to harm their cause.
        They may catch more of the minor crimes, like someone looking at pics because he or she is curious and mildly titillated, but it won't stop the tech savvy distributors and technologically advanced networks.

      • by arth1 ( 260657 )

        The problem with perceptual hashes is that the false positive rate is way higher.
        That's not a good thing when dealing with something like CP, where mere allegations or investigations can ruin a person's life, even if innocent, because no-one is going to believe that there was smoke without fire.

      Being a paedophile is a crime in the UK. For example, you can produce hand drawn images or written stories about paedophilia and be convicted of a crime for doing it. There is no victim, only your own imagination was involved. Expressing certain thoughts and ideas is a crime in the UK.

      When they claim that there are "tens of millions" of images in this database, I wonder how many are of victims and how many are cartoons found on 4chan or scans of children's clothes catalogues and that sort of thing. Yes, clothes catalogues are illegal if kept for the purposes of sexual gratification.

      Also, they claim to use more than just images hashes. They say facial recognition and the ability to handle images that have been scaled, mirrored or otherwise adjusted.

        Being a paedophile is not a crime in the UK. Actions resulting from it are.

        Hand drawn images are illegal, and it's fucking insane. I'm tempted to create a website that shows you an image of a stick man and stick woman shagging, with the label "Man fucking woman". Add a button that changes the word 'woman' to '12 year old girl' and anybody clicking that button will break the law by producing what in the UK is legally defined as child pornography.

  • Some of the files in question may have been subject to change as they were moved from host to host, an analog to mutations in virii. By analyzing the 'mutations' in the image files, it may be possible to gain some insight into the paths the various iterations of the same image took before being found by law enforcement.

    OK call me old-fashioned, but I totally misread the headline.

    I thought this was about general child abuse, not just the sexual subset, which could be a just a small part of overall child abuse. What I was thinking of was things like poor treatment by parents, such as receiving beatings or insufficient food or having to live in a terribly dirty home, all that kind of abuses. The kind of abuse children have to be removed from their home for, placed with foster parents, etc.

    In other countries, mostly eliminated in the UK, there are of course also issues such as child labour (children forced to work long hours in dangerous or hazardous conditions), depriving children of access to education (particularly girls in Muslim countries), and other serious and highly widespread forms of abuse.

    Not to gloss over sexual abuse, which can be pretty bad as well of course, there's a lot more to "child abuse" than just "sexual child abuse". However equating "child abuse" to "sexual child abuse" makes us forget the other forms of abuse, which I strongly believe are far more widespread than sexual abuse. But maybe those are simply not as sexy, politically.

      In the UK, child sexual abuse has been a tabloid-driven panic-issue for many years. The government is very eager to be seen doing something about it. Not because it's any more common here than elsewhere in the world, but because every time someone gets caught after going undetected for years there's a media field day, which in turn means an investigation into why they weren't caught sooner, and someone has to bear the public's wrath.
