BBC reporter Angus Crawford offers insight into the “deep web,” which used to be a completely secure way for the consumers of child pornography to hide their online activity. However, many international agencies are now investigating methods to track down the perpetrators. This is an excerpt from a recent article published by BBC News.

One site receives as many as 500 page views per second, its founder says.[…]
Britain’s National Crime Agency warned in its 2014 threat assessment that abusers were turning to anonymous sites and encryption technology.
The dark net is the term used to refer to parts of the internet that are hidden and can be hard to access without special software.
One of the most popular products used to access such areas is called the TorBrowser.
It allows people to use Tor, an “onion-routing” system which makes a PC’s net address untraceable by bouncing the encrypted data it sends through several randomly selected computer servers on a volunteer network – each of which removes a level of encryption – before it reaches its destination.
There are also many hidden sites on the network ending in the .onion suffix, which cannot be found using Google or other regular search engines.
Tor was first created by the US military but is now also used by pro-democracy campaigners, whistleblowers and journalists operating under repressive regimes.
It was used by activists during the Arab Spring to avoid detection.
But criminals are also taking advantage of its anonymity.[…] The threat posed by these kinds of sites has been recognised by governments around the world.
In November, the British prime minister, David Cameron, held a summit at Downing Street on online safety.
He said he expected the spy agencies and GCHQ to lend their skills to the police.
“That expertise is going to be brought to bear, to go after these revolting people sharing these images on the dark net,” he said.[…]
Several countries’ police forces are working together, under the banner of The Virtual Global Taskforce, to tackle online child exploitation worldwide.
The body’s chairman, Ian Quinn, said Tor was an emerging threat.
“It’s certainly a challenge, I’m hesitant to describe law enforcement techniques but it’s something we’re definitely keeping an eye on.”[…]
Greg Virgin runs software company Redjack and is helping the human rights group International Justice Mission, which campaigns against child abuse.
He uses complex algorithms to mine dark net chat rooms for data.
“The typical law enforcement approaches to finding out what computers are being used are no longer available,” he said.
But by analysing the traffic on one particular site, he says he’s able to find out much more about its users.
Of more than 10,000 users, he said 2,000 were “producers of content”, meaning child abusers who post pictures of that abuse on the site.
Of these, 20% were from the UK, he said.
In several postings users refer to living in particular parts of the UK and ask to arrange meetings.
“They actually divide themselves up into regions – the South West, South East, North East and London,” Mr Virgin observed.
He added the site was actually encouraging abuse.“It’s a guide for paedophiles and a support system for paedophiles to get more extreme.”
Dark net disgust
The website DeepDotWeb.com reports on dark net developments.
“On Tor I know about probably 20 to 50 sites from looking at public directories but I guess there are more that are not as public,” said its founder, who wanted to remain anonymous.
He added that most deep net users were “disgusted” by the paedophile sites.
“The ‘deep web’ is still, just an open reflection of the real world thanks to its anonymous conduct, so this problem needs to be tackled in the real world.
“The ‘deep web’ is nothing more than a peep hole into this unfortunate reality.”
