Children's charity Barnado's and Microsoft have released an app to help children learn how to spot the signs of sexual exploitation.
One of the victims insists some of the abusers are still walking the streets of Rochdale and blames police for continued failings.
The search engines have stepped up to the plate - their reforms will help remove video child abuse content more quickly and comprehensively.
In total the number of cases involving Britons or the UK as country of origin rose 173% to 90; of those, 63 were children.
– Liam Vernon, Head of the NCA's UK Human Trafficking Centre.
Increased awareness, both of human trafficking in its various forms and the obligation of first responders to use the National Referral Mechanism, is a likely contributor to the increased number of referrals in 2013.
We know that this is a crime which affects some of society's most vulnerable people, and some victims will remain undetected.
Equally, some of those referred to the NRM may not ultimately be classified as victims of human trafficking.
The NCA is committed to relentlessly disrupting what is a criminal trade in human misery.
Of the number of minors identified as potential victims, 45 were classed as possible domestic servitude (up 2% on 2012), 123 as labour exploitation (up 24%) and 138 were unknown (up 9%).
Of the adults, 141 were classed as domestic servitude (up 18%), 511 labour exploitation (89% rise), 581 sexual exploitation (53% rise), and 62 unknown (up 44%).
New NCA figures on trafficking show that for children the most common nationality or country of origin was Vietnam, followed by the UK and then Albania.
The figures are the number of cases highlighted under the National Referral Mechanism (NRM), used to bring possible victims to the authorities' attention.
The NCA said that 1,746 people from 112 different countries were highlighted as as potential victims of traffickers last year, up 47% on the previous year. Nearly two thirds of those referred were female (1,122) and around a quarter (450) were children.
The number of UK-born children identified as being trafficked for sexual abuse more than doubled last year.
Data released by the National Crime Agency (NCA) showed that 56 minors who are from the UK were flagged up as potential victims of trafficking for sexual exploitation in 2013, a rise of 155% on the previous year.
It is not clear whether they were being taken out of the country or moved within the UK, the NCA said. The number of foreign children identified as being at risk also rose by 11%, to 88.
Training for education, healthcare and children protection workers in technology used to abuse children online is "an absolute must", the NSPCC have said.
Jon Brown, the NSPCC lead on tackling sexual abuse, added:

Training to protect children from online abuse is an absolute must for those in social work, health, education and law.
It won't necessarily make them experts but will help them stay in touch with a rapidly changing technological world which poses a variety of risks for the young.
The overwhelming majority of professionals who care for abused children admit they have had no training in how to help children recover from the online element, a survey revealed.
A poll of 692 school nurses, health visitors, paediatricians, social workers, child protection advisers, family and education welfare officers, teachers and learning support assistants also found:
- Of the 81% who said they had not been trained in how to help children recover from the online element of their abuse, 94% added they wanted that training.
- 70% of those stated they had not received training in online risk assessment.
- 95.5% saying they would value such training.
Professionals looking after child abuse victims cannot properly support them because they are not trained to understand the technology used by perpetrators, academics have found.
A group of University researchers revealed a black hole in the knowledge of education, health and children's services staff, as they cannot keep up with the online technology used to abuse children.
The study, carried out by researchers at Plymouth University and University Campus Suffolk for victims' charity Marie Collins Foundation, found pedophiles have become more ingenious in their use of technology to engage with vulnerable children.
However, the training available to professionals has not kept up.
Andy Phippen, professor at Plymouth University, said: "The fast pace of its development has in many cases left the authorities playing catch-up and while some now have policies in place, a huge amount of work is required to ensure those affected by online abuse receive the correct support."
Pope Benedict XVI defrocked nearly 400 priests over just two years for molesting children according to a document obtained by the Associated Press.
The statistic, which relates to 2011 and 2012, emerged in the testimony of the Vatican's UN ambassador in Geneva, Archbishop Silvano Tomasi, before a UN committee.
The Holy See has had to defend itself before the UN human rights committee this week following reports of widespread child abuse in the Catholic Church.
Previously, the Vatican has only revealed the number of alleged cases of sexual abuse it had received.
An inquiry was prompted when Northamptonshire Police visited registered sex offender Timothy Ford and began tracking the international abuse network from obscene videos they found on his computer. He was paying to view live sex abuse and planned to move to the Philippines to open an internet cafe
– National Crime Agency statement
The use of webcams to stream live abuse, particularly from the developing world, is a significant and emerging threat according to the NCA's CEOP (Child Exploitation and Online Protection) command.
Extreme poverty, the increasing availability of high-speed internet and the existence of a vast and comparatively wealthy overseas customer base has led to organised crime groups exploiting children for financial gain.
Instead was jailed for eight-and-a-half years in March last year.Another member of the paedophile network, Thomas Owen, who had nearly four million images of child abuse when he was arrested, was jailed for seven years in July last year.
The National Crime Agency said that a joint police investigation had identified "extremely dangerous child sexual offenders".
– Andy Baker from the National Crime Agency
This investigation has identified some extremely dangerous child sexual offenders who believed paying for children to be abused to order was something they could get away with.
Being thousands of miles away makes no difference to their guilt. In my mind they are just as responsible for the abuse of these children as the contact abusers overseas.
Protecting the victims of abuse is our priority and that means attacking every link in the chain, from dismantling the organised groups who are motivated by profit through to targeting their customers.
So far 15 children aged six to 15 have been rescued after being identified as victims. In some cases their own relatives sold them for abuse.
In the UK five of the 17 suspects arrested have been convicted, nine investigations are ongoing, one will face no further action and two are dead.
Police officers from Britain have joined forces with Australian and US investigators to smash a paedophile ring which streamed live child abuse from the Philippines.
The investigation, which has been going on for two years, focuses on what the UK's National Crime Agency calls "a significant and emerging threat", particularly in developing countries.
Three other investigations are taking place into live streaming of child sex abuse, with 139 Britons among the 733 suspects.
So far 17 Britons have been arrested as part of the Philippines inquiry, Operation Endeavour, which has spanned 12 countries and has seen involvement from police in the UK, Australia and the US.
