Jim, when will you be implementing PhotoDNA into Holla Forums? Facebook, Google, Gmail, Yahoo, Twitter...

First, what makes you think it hasn't already been implemented?
Second, why would Jim have to implement it when the Feds already monitor the site in real time?
Third, why would you even care?

Not only that, but PhotoDNA is only effective for photos already in its database. It doesn't stop, or even slow down, the production and creation of new images, it only prevents the redistribution of old ones. in essence, PhotoDNA does nothing but serve to keep online pedo content as fresh as possible, which actually would have a tendency to drive up demand if what they teach in business colleges is correct.

lol feds don't monitor this site.

he should be since Holla Forums is hosted in the US, it's required by law to report illegal images to the NCMEC and any information on record about the poster.

photo dna only flags images on the database to which they are compared. this means any oc and many marginal images like laurab are not included. it wouldn't help much here because most of the stuff pedos post is legal outside of the context of a pedo site like Holla Forums. the system also costs money which jim needs for pigfeed and relies on competent, rapid moderation to take down the images and report the poster - or his vpn.

PhotoDNA is meant to catch 40 year old normies trying to trade CP on gmail and dropbox. And it's been highly effective.

PhotoDNA is meant for sites that get millions of private uploads a day. Those sites are impossible to moderate.

Global mods here are capable of dealing with illegal images and reporting them to the appropriate authorities.

Um, alarming as it is, this is correct. The more successful PhotoDNA gets, and the more widely it gets implemented, the more it will drive up demand for new (not in the database) content. How did they not take that into account???

So is driving the speed limit.
The question is, what is the penalty for not doing it, and how often is that actually enforced? The answer is "There is an insignificant and Constitutionally dubious penalty that is almost never enforced because it is next to impossible to prove intentionality in court." Especially against someone who is in the Philippines. He is already wanted for tax violations in the US, what is violating that law to him? Nothing, that's what.

Wake up and learn something about who you are talking about, FFS.

this is stupid, they'll just use something other than twitter, facebook or tumblr. in dropbox all they need to do is rar the files and put a password on it

*pats you on the head*
You are so cute. Don't ever change.

Oh look its the commies with their pedo meme again

they investigate credible reports, but actively monitoring some irrelevant chan is a waste of resources.

whoaaa. shit. so the antipedos are just making more little girls get raped.

You should also learn something about the government you are talking about. Wasting resources is what they do. And while 8ch may be irrelevant to you and me, it certainly is not irrelevant to the Federal Government of the USA, which monitors ALL major social media in real time as well as specific lesser used social media websites like the chans. How do you survive not knowing any of this stuff??? Do you even read basic publicly available documentation on how your government's public surveillance system operates?

That is the logical implication, yes.

A lot of tech literate pedos actually like PhotoDNA, it allows law enforcement to scoop up thousands of low hang fruit in one bust. The prosecutors and LEA get good press and do it all over again.

The tech pedos believe it attention away from them which requires lengthy intesive investigating.

bitch please, we don't need any Orwellian shit in here.
pedo or not, this stuff has no place on Holla Forums.

I was looking up some PhotoDNA cases

lol at how descrptive police are when describing the CP they found, seems like they get off to it

I'm 100% in favor of this, but I wouldn't expect an announcement if it was implemented. Imagine the meta butthurt and goon spam that would flood the catalog.

What the fuck. Why would they go into so much detail? AFAIK they never show CP to jurors in court rooms, so even if this was a court document there's no reason for that much detail.

I wonder how many pedos seek out these kinds of jobs. Probably #3 behind high school coach and Catholic priest.

it's a bit far fetched. the database is constantly updated and the producers jailed. this won't result in more fresh cp being posted online, especially if all the other efforts to prevent child abuse play a part.
the pdna is intended to reduce the availability of cp online and it does this. the worst offenders might be encouraged to make oc, but every new image of a serious nature is investigated by the feds, who want to catch the producers and distributors much more than than they want to catch your average wankchampion from Holla Forums.
if a lot of pedo oc was posted here, even if the mods removed it in a timely fashion as the law requires, the feds would be on the posters' asses like a swarm of bees.

Yes. This has been true for decades at least. Child abuse is primarily a result of social alienation and depression. People who hate society and have nothing left to live for are prone to do terrible things. People who have mutual respect for society and feel optimistic about their future aren't inclined to throw it all away in an act of senseless harm.

The fact that the police do everything in their power to prevent pedophiles from masturbating is just the icing on the cake of stupid, counterproductive policy.

Oh, are you claiming that demand doesn't cause more to be produced? Wouldn't that invalidate the entire argument against CP being illegal if it were true?
PhotoDNA cannot catch producers.

in a free market you could argue that rarity would cause a price rise, followed by an increase in production. cp isn't a free market at all, tho. the database is one weapon in a varied arsenal employed to restrict identify and prosecute cp makers. the database serves to deliver offending ips to the feds and alert them to the appearance of oc, so it does help catch producers and save children from this trauma. not perfect is better than not at all.

No, it cannot do this. You are either misunderstanding how it works or willfully lying.
It can give some indication of whether an image is OC after it has been discovered, but it cannot detect such images automatically.

More generally, reducing the availability of child porn does not help save children. In every instance where a society has tried to ban porn, rapes have increased immediately afterwards. The strategy is counterproductive and fundamentally unethical.

Actually, for something like photoDNA I'm not sure it would be a strictly one-way conversion. It depends on whether the number of bits of entropy in the hash is less than the number of bits of entropy which an image is reduced to by the fuzzy matching algorithm.

Given massive computing resources it's probably possible to use PhotoDNA to reverse engineer an approximation of a given image by brute force. Fuzzy hashing algorithms are inherently vulnerable to standard optimization algorithms. Adding additional filters such as a neural network trained to recognize photographs of humans could help eliminate false positives and extract a few extra bits of entropy from the hashed value.

That said, unless the hash stored by PhotoDNA is extremely long, any image you got out of such an approach would be extremely low resolution and/or noisy. You'd probably be better off just drawing your own porn with a pencil (2D>3D anyway). Then again, I doubt the evil fucks who throw people in cages for decades would care how low resolution an image was.

Actually, correction, it is always reversible given sufficient computing resources. The better PhotoDNA is at excluding false positives, the easier it would be to reconstruct the full image.
