UK Government Urges Apple and Google to Block Nude Images on Children's Phones

On June 8, 2026, at London Tech Week, UK Prime Minister Keir Starmer issued an ultimatum to Apple and Google: make it impossible for children to take, share, or view nude images on their smartphones and tablets within three months, or face legislation that could bring fines and criminal liability for senior executives [1][2]. Home Secretary Shabana Mahmood said the government was not interested in "surveilling or policing" people's phones, insisting: "There is no reporting, no data collection, no monitoring, and no images leaving the device" [3]. Adults would retain access to explicit content through an age-verification process.

The announcement came against a backdrop of record-breaking child sexual abuse imagery online and a surge in sextortion cases targeting minors. But it also reopened a familiar fault line between child protection and digital rights — one that Apple itself walked away from in 2022 when it abandoned its own plan to scan for child sexual abuse material (CSAM) on iPhones [4].

The Scale of the Problem

The Internet Watch Foundation (IWF) confirmed a record 291,273 reports of child sexual abuse imagery in 2024, up from 275,655 in 2023 and 132,676 in 2019 [5]. Of the reports where victims' sex was recorded, 97% depicted the abuse of girls [5]. The IWF also identified a 72% increase in children and young people reporting sexual extortion between the first half of 2024 and the same period in 2025 [6]. The number of commercial child sexual abuse sites the IWF discovered in 2025 doubled since 2024, from 7,028 to 15,031 [7].

Government data cited in support of the policy indicates that 91% of online child sexual abuse reports recorded in 2024 contained self-generated content — images produced by the children themselves, often under coercion [8]. Boys aged 14-17 accounted for 98% of all reports involving sexually coerced extortion through the IWF's Report Remove helpline [6].

Meanwhile, UK children are getting smartphones at increasingly young ages. The average age a child receives their first smartphone is now 8.9 years [9]. By age 8-11, 61% of UK children own a smartphone; by 12-15, that figure reaches 82% [10].

What Is Actually Being Proposed?

The government's demand is framed broadly: tech companies should "activate nudity-detection algorithms or other technical solutions" at the device level to prevent children from taking, sharing, or viewing explicit images [1][2]. The proposal is deliberately technology-agnostic — it specifies an outcome rather than prescribing a specific mechanism.

This matters because the technical approaches vary significantly in their implications.

On-device nudity detection uses machine learning models running locally on the phone to identify images that appear to contain nudity and blur or block them before a child can view them. Apple already offers this through its Communication Safety feature, introduced in iOS 15.2 and enabled by default for children's accounts. It covers Messages, AirDrop, FaceTime, shared photo albums, and some third-party apps [11]. Google has built similar parental controls into Android's Family Link. An Apple Insider analysis of Starmer's announcement noted the irony: "The government appears unaware the technology already exists" [12].

CSAM hash-matching — the approach Apple proposed and then abandoned in 2021 — works differently. Rather than detecting nudity in general, it compares cryptographic "hashes" (digital fingerprints) of images on a device against a database of known child sexual abuse images maintained by organizations like the National Center for Missing & Exploited Children (NCMEC). Apple scrapped this plan in December 2022 after a coalition of cryptographers, the Electronic Frontier Foundation, and even some Apple employees warned it created infrastructure that could be repurposed by governments to scan for any content, not just CSAM [4][13].

Age verification is the third piece. Under the proposal, adults would need to verify their age to take or view nude images on their devices. This requires some form of identity or age-assurance mechanism, raising immediate tensions with UK GDPR principles around data minimization [8].

The government has not published technical specifications or an impact assessment for any of these approaches.

The Apple CSAM Precedent

Apple's abandoned CSAM detection system looms over this debate. In August 2021, Apple announced it would scan photos uploaded to iCloud against a database of known CSAM hashes. The system was designed so that only after a threshold number of matches would Apple be notified — below that threshold, the company would learn nothing about a user's photos [4].

The backlash was immediate and broad. Security researchers argued the system created a "backdoor" — not because Apple intended misuse, but because the scanning infrastructure, once built, could be compelled by governments to search for other types of content [13]. In December 2022, Apple quietly killed the project, with vice president Craig Federighi confirming the decision. Apple instead expanded Communication Safety, its on-device nudity detection feature that warns children but does not report to Apple or law enforcement [4][11].

Apple's chief privacy engineer Erik Neuenschwander later explained: "Scanning every user's privately stored iCloud data would create new threat vectors for data thieves to find and exploit... It would also inject the potential for a slippery slope of unintended consequences. Scanning for one type of content, for instance, opens the door for bulk surveillance and could create a desire to search other encrypted messaging systems across content types" [13].

The question facing Starmer's government is whether any device-level blocking system can avoid the same slippery slope. What specific technical and legal safeguards would prevent future governments — whether in the UK or in countries that import the technology — from expanding the scope of blocked content to include, for example, political dissent, LGBTQ+ material, or legal adult content?

Existing Frameworks and Why the Government Wants More

The UK already has substantial legislation in this space. The Online Safety Act 2023 places duties on platforms to protect children from harmful content, with Ofcom as the regulator. Ofcom can impose fines of up to £18 million or 10% of qualifying worldwide revenue, and has criminal liability provisions for executives [14]. By late 2025, Ofcom had launched five enforcement programmes and opened 21 investigations [15].

Parental controls already exist on both iOS and Android. Apple's Communication Safety feature detects and blurs nudity in messages and other apps for children's accounts [11]. Google's Family Link offers content filtering, app restrictions, and screen time controls. Neither platform makes these features mandatory for all child accounts by default in all jurisdictions.

Internationally, Australia banned social media for children under 16 in December 2025, with penalties of up to A$49.5 million for non-compliant companies [16]. France approved legislation banning children under 15 from social media [16]. The European Parliament called for an EU-wide ban on platform access for under-16s without parental consent [16].

The government's apparent rationale for going further is that existing tools are opt-in, inconsistently enabled, and do not cover the full range of scenarios — particularly the camera app itself and third-party messaging services. The proposal would make protection mandatory and device-wide rather than app-specific.

Who Is Most at Risk — and Does One Solution Fit All?

The evidence base suggests the problem is not monolithic. At least three distinct scenarios drive the statistics:

Sextortion by criminal networks. The NCMEC recorded 23,593 reports of financial sexual extortion in the first half of 2025, up from 13,842 in the same period of 2024 — a 70% increase [6]. These cases typically involve organized criminals, often operating from West Africa or Southeast Asia, who trick or coerce children into sharing explicit images and then demand payment. Boys are disproportionately targeted [6].

Peer-to-peer sexting among teenagers. Research estimates that 15-40% of UK young people have participated in sexting [17]. An ESET survey found 39% of respondents first shared explicit content while underage, with the average age of first receiving a sexual image being 14 [18]. The College of Policing and Crown Prosecution Service guidance distinguishes between "aggravated" cases involving coercion and "non-aggravated" cases where images are shared willingly between peers, recommending against routine prosecution of the latter [19].

Self-generated imagery under coercion. The IWF found that 72% of the 252,194 webpages it actioned in 2021 contained self-generated imagery [20]. This is the category most directly cited by the government.

Each scenario may require a different intervention. Device-level nudity blocking could plausibly interrupt sextortion workflows and reduce self-generated imagery. Its effect on peer-to-peer sexting is less clear — teenagers determined to share images could use devices not tied to a child account, borrow adult devices, or use platforms outside the Apple/Google ecosystem.

The Displacement Problem

Child safety advocates and critics alike acknowledge a core tension: if Apple and Google block nude images on children's devices, will abusers and determined teenagers simply move to encrypted messaging apps, burner phones, or other platforms?

"No technical solution is a silver bullet," is a common refrain among researchers. The government has not published a Home Office impact assessment quantifying expected harm reduction from the proposed measures. No peer-reviewed study directly measures whether device-level blocking reduces overall harm versus displacing it to other channels.

The National Crime Agency, however, welcomed the announcement, arguing that "device restrictions have the potential to prevent some of the most serious forms of online child sexual abuse before they begin" [3]. The logic is that friction matters — making exploitation harder at the most common access point (mainstream smartphones) reduces the total volume of abuse, even if some activity migrates elsewhere.

Academic research on the topic has grown substantially, with over 58,000 papers published on child sexual exploitation online since 2011 and a peak of 6,835 publications in 2023 [21]. But the specific question of whether device-level interventions reduce harm at scale remains understudied.

Privacy and Civil Liberties Concerns

The sharpest criticism has come from digital rights organizations. Big Brother Watch director Silkie Carlo called the proposal "a crossing of the Rubicon," warning it "would make the UK one of the most authoritarian internet regimes in the world" [3]. Carlo argued the requirement for age verification on all devices amounts to mandatory ID checks, and that on-device scanning software would inevitably be "exploited for other purposes before long" [3].

The Open Rights Group has consistently argued that age-verification measures do not protect children and create new privacy risks [22]. Their research documents how content-filtering systems routinely over-block, flagging legitimate LGBTQ+ content, sex education resources, and domestic abuse support services as "adult" material [23].

The concern is not hypothetical. Platforms including Tumblr and YouTube have been documented mis-classifying non-explicit LGBT-related content as "mature" or "adult," preventing young people from accessing content about rights, history, identity, and discrimination [23]. Some school filtering systems block access to LGBTQ+ youth organizations and alert administrators when students search for related topics [23].

The government has not published an equality impact assessment for the proposal. It has not addressed how the system would handle LGBTQ+ youth who rely on private digital communication for safety, survivors of abuse who may need to document evidence photographically, or young people accessing age-appropriate sex education content.

Commercial and Legal Exposure for Apple and Google

The legal landscape creates a complex calculus for both companies. Under the Online Safety Act, Ofcom can fine non-compliant services up to 10% of global revenue — which for Apple (2025 revenue: approximately $390 billion) could mean fines in the tens of billions [14]. Criminal liability for senior executives is a statutory backstop [8].

However, Starmer's announcement is currently an informal demand, not a statutory notice. No formal enforcement action under the Online Safety Act has been taken against either company specifically on this issue [15]. The three-month deadline is a political ultimatum backed by a threat of future legislation, not an existing legal obligation.

Apple faces an additional dilemma. It already offers Communication Safety and has positioned privacy as a core brand value. Complying with a government mandate to expand on-device scanning could undermine its privacy narrative and set a precedent that other governments — including those with poor human rights records — would seize upon. Refusing to comply risks regulatory confrontation in one of its largest markets.

Google's Android ecosystem presents different challenges. Unlike Apple's relatively controlled environment, Android's open architecture means device-level blocking must work across thousands of device manufacturers and software configurations.

Neither company has issued a formal public response to Starmer's announcement as of June 8, 2026.

What Happens Next

The three-month clock runs to approximately September 2026. If Apple and Google do not satisfy the government's demands, ministers have said they will introduce legislation mandating the changes. That legislation would need to pass through Parliament, where it would face scrutiny from both child safety advocates pushing for stronger measures and civil liberties groups warning of overreach.

The proposal also arrives as the Online Safety Act's enforcement regime enters its most active phase. Ofcom is expected to publish additional requirements for the largest service providers by summer 2026 [15]. The intersection between these existing regulatory processes and Starmer's new demand remains unclear.

Several questions remain unanswered. Will the government publish technical specifications? Will there be an equality impact assessment addressing concerns about LGBTQ+ youth and abuse survivors? Will the mandate extend beyond Apple and Google to other device manufacturers? And can any system reliably distinguish between a 17-year-old's consensual peer interaction and a criminal's coercion — or will it treat all nudity on a child's device identically?

The stakes are real on both sides. Record levels of child sexual abuse imagery and a surge in sextortion demand action. But the history of content-scanning proposals — from Apple's abandoned CSAM system to the UK's own contested age-verification efforts — suggests that the gap between political ambition and technical reality is where the hardest questions live.
