This is an Internet Watch Foundation (IWF) news release dated 8 June 2026. It welcomes the UK Government's call for nudity detection and blocking on children's devices. Independent reporting confirms the policy event itself. On 8 June 2026, at London Tech Week, Prime Minister Keir Starmer gave Apple, Google and other firms three months to detect and block nude images on children's smartphones and tablets, and the Home Office said it would legislate if they did not. Most of the statistics match the IWF's 2025 Annual Data & Insights Report and its consultation response. These include the record 311,610 confirmed reports, the 85% self-generated share, the 111,610 images and 28,666 videos, and the 25% (images) and 45% (videos) shares. Two figures could not be found in any other source: the 266,397 report count and the 18% (25,092) Category A figure. Both are arithmetically consistent with the verified totals. Named officials and their roles are confirmed. The main weaknesses are in presentation. The headline says the government is 'requiring' firms to act, when at publication this was a three-month voluntary ultimatum backed by a threat of legislation. The release also leaves out the widely reported privacy and feasibility objections from civil-liberties groups. As expected for an advocacy organisation, it speaks for its own policy position.

What checked out (8)

The UK Government publicly asked tech companies to put nudity detection and blocking on children's devices. VERIFIED: The Record (8 Jun 2026), CARE (8 Jun 2026), Holyrood and Lewis Silkin (11 Jun 2026) all report Starmer's London Tech Week announcement and the Home Office's three-month deadline, with legislation threatened if firms do not comply.
The IWF responded to the Government's national consultation on children's online safety ('Growing up in the online world'), recommending device-level nudity detection and blocking alongside other child-protection organisations. VERIFIED: IWF consultation page and response PDF (dated May 2026, including CSEA-sector recommendations). Lexology, Mishcon de Reya and Faegre Drinker confirm the consultation exists.
In 2025 the IWF acted on a record 311,610 reports confirmed as child sexual abuse material. VERIFIED: IWF 2025 Annual Data & Insights Report Executive Summary (+7% year on year) and the IWF annual report archive ('record levels'). Small nuance: the report's wording is 'confirmed as or linked to' CSAM.
85% of actioned reports contained at least one 'self-generated' image or video. VERIFIED: the IWF consultation response PDF says the share was 91% in 2024 and 85% in 2025.
111,610 images and 28,666 videos were assessed as 'self-generated' CSAM, which is 25% of all criminal images and 45% of all criminal videos. VERIFIED: IWF 2025 report, 'Self-generated imagery' page (140,276 self-generated items out of 512,980).
The IWF has been raising the alarm about self-generated material since 2012. VERIFIED: an IWF study of self-generated sexually explicit content was carried out over four weeks in September 2012.
Kerry Smith is IWF Chief Executive. VERIFIED: Wikipedia infobox and the IWF X account (May 2026). A shorter version of her quote also appears on IWF's Bluesky feed.
Ngaire Alexander is IWF Head of Hotline. VERIFIED: Cambridge Independent and inkl/Guardian syndication (Jan 2026) and The Investigator.

✕ Disputed claims 1 claim ⌄

IMPRECISE FRAMING, NOT FALSE: the headline says the government 'move requir[es] tech companies to urgently implement' nudity blocking. When the release was published (8 Jun 2026), this was a request with a three-month deadline and legislation threatened if firms did not comply, not a legal requirement already in force (The Record, Holyrood, Lewis Silkin). Later reports (MacDailyNews and IBTimes UK, Sept 2026) suggest the Government is moving towards legislation, but this happened after publication.

? Unverified claims 4 claims ⌄

266,397 reports contained at least one self-generated image or video. UNVERIFIED by any other source; the figure appears only in this release. It is internally consistent: 266,397 / 311,610 = 85.5%, which matches the verified 85%.
18% (25,092) of self-generated images and videos were Category A. UNVERIFIED by any other source. The report's self-generated imagery page only says 53% were Category C. The figure is internally consistent: 25,092 / 140,276 = 17.9%.
The IWF runs 'Europe's largest centre' for assessing and removing CSAM. PARTLY VERIFIED: this is the IWF's consistent self-description across many of its own releases, but no independent comparative ranking was found.
Enforced nudity detection would have an 'instant and positive impact' by stopping new abuse content being generated. UNVERIFIABLE: this is a forecast or opinion. Critics, including the Age Verification Providers Association, as quoted by Planet Nude, and TechRadar, question whether it is technically feasible.

⌕ Sources & how we checked Search journal, source grades, confidence ⌄

Confidence

High (about 0.85) — Four or more independent, dated sources confirm the central policy event. Most statistics match the IWF's published 2025 report and consultation response, and every figure passes arithmetic consistency checks. Named roles were confirmed by sources from 2026. Confidence is slightly reduced for three reasons. Two specific figures (266,397 and 25,092) appear only in this release. The IWF's own report is not independent. The gov.uk press release was confirmed only through outlets quoting it, not opened directly.

# On-device nudity detection has ‘powerful role to play’ in fight against child sexual abuse online

Published:Mon 8 Jun 2026

**IWF backs government move requiring tech companies to urgently implement nudity detection and blocking on children’s devices.**

The Internet Watch Foundation (IWF) has thrown its support behind the UK government’s demand for tech companies to better protect children with on-device safeguards, calling the move pivotal among a raft of much-needed measures in the battle against child sexual abuse material.

The call to implement on-device nudity detection and blocking on children’s devices is one of several measures the IWF has recommended along with other child protection organisations in [the Foundation’s response]( "Our response - Growing up in the online world: a national consultation") to the government’s recent national consultation on children’s online safety.

Enforced nudity detection on children’s devices would have an instant and positive impact by preventing the generation of new child sexual abuse content, says the IWF, an international not-for-profit organisation which operates Europe’s largest centre for assessing, grading and securing the removal of child sexual abuse material online.

Since 2012 the IWF has been [raising the alarm]( "IWF Research") about the grooming and coercion of children leading to ‘self-generated’*material, whereby a child or children appear in sexual abuse imagery without a perpetrator physically present. The consequences of the abuse and subsequent sharing of the content online can be devastating for the children and the families involved.

Last year (2025), the IWF took action on a record 311,610 reports where analysts confirmed the presence of child sexual abuse material. Of these, 266,397 reports contained at least one ‘self-generated’ image or video. This is 85% of all the reports actioned.

During the same period the IWF assessed 111,610 individual images (25% of every single image confirmed as criminal) and 28,666 videos (45% of every single video confirmed as criminal) as showing criminal ‘self-generated’ child sexual abuse.

18% (or 25,092) of these images and videos were Category A – the most extreme category of sexual abuse in the UK which can include rape, sadism or bestiality.

**Ngaire Alexander, IWF Head of Hotline**, said:_“In the Hotline we see how children are groomed and coerced online into creating and sharing nude and sexual images of themselves, which can then start a spiral of abuse._

_“These images or videos are recorded by someone, or many people who are not physically within the home, but who could be anywhere in the world._

_“Now imagine if we had a world where internet connected devices simply didn’t allow sexual images to be captured and transferred. We could save a child from so much trauma, shame and humiliation. A world of pain could be prevented.”_

The IWF’s consultation response set out urgent recommendations to tackle child sexual abuse and exploitation online, including device-level protections, and highlighted that no single intervention is enough.

**IWF CEO Kerry Smith** said: _“On-device protections are a pivotal part of coordinated, multi-layered approach to safeguarding children online. An alarming amount of child sexual abuse material, which our analysts see every day, is self-generated by children as a result of grooming, coercion or manipulation. We need device-level detection and blocking alongside platform-level protections._

_“That is why we warmly welcome the government’s announcement and see these protections as playing a powerful role in a whole-system response to the threats children face in digital spaces. With nudity blocking in place, it will make it much harder to create new images and videos of child sexual abuse and better protect children from harms on the internet.”_

*The term ‘self-generated’ child sexual abuse is an inadequate and potentially misleading term which does not fully encompass the full range of factors often present within this imagery, and which appears to place the blame with the victim themselves. Children are not responsible for their own sexual abuse. Until a better term is found, however, we will continue to use the term ‘self-generated’ as, within the online safety and law enforcement sectors, it is well recognised.
