The UK Will Scan Asylum-Seekers’ Faces for Age Checks—Despite Knowing the Tech Is Flawed

Age verification is consuming the internet. From societal media bans successful Australia to porn restrictions successful fractional of US states, for galore having to beryllium their property to entree websites is becoming an mundane requirement. But 1 of the cardinal technologies underpinning galore of these property checks is astir to seep into the offline world—with perchance life-changing consequences for radical having their property predicted by AI.

Starting adjacent year, the British authorities is readying to present facial property estimation—where AI scans your look and suggests however aged you are—to assistance find the property of asylum seekers arriving astatine the United Kingdom’s border. The determination is believed to beryllium the archetypal clip that a alleged facial property estimation (FAE) strategy has been utilized successful this way. Many asylum seekers arriving successful the UK volition not person documents proving their age, and if children are incorrectly classed arsenic adults, they tin beryllium stripped of immoderate ineligible protections and placed successful adult-only detention centers.

An probe by WIRED and Lighthouse Reports, successful collaboration with The Independent, has obtained an interior UK authorities study detailing its tests of FAE technologies. It shows however the systems regularly mistake children for adults and look to incorporate superior bias problems, which straight interaction the largest radical of migrants taxable to property assessments successful 2025, according to information from the Home Office. The probe raises questions astir the effectiveness of the exertion and whether it should beryllium deployed successful specified high-stakes scenarios.

The findings besides travel arsenic the 2nd Trump medication and governments astir the satellite progressively follow anti-migrant policies portion spending billions connected surveillance exertion that is often deployed against susceptible radical who person small cognition of its use, however it works, oregon ways they tin situation it.

The leaked Home Office papers obtained by Lighthouse Reports mostly details the “best” performing of 7 facial property estimation algorithms that the section tested past year, though it does not straight sanction the companies down them. The study recovered that the strategy performed importantly worse erstwhile it was utilized to estimation the ages of Sub-Saharan Africans compared to different groups. Sub-Sarahan Africans are the largest radical of migrants entering the UK aft crossing the English Channel successful tiny boats successful caller years and had much property assessments raised successful 2025 than cohorts from different regions, according to Home Office data. For pistillate Sub-Saharan Africans, the property that the strategy guessed was disconnected by an mean of 4.6 years, meaning that a 13.5-year-old miss could beryllium assessed arsenic an 18-year-old adult.

The probe besides recovered that the Home Office, which oversees UK migration and policing, disbanded a technological committee designed to counsel it connected broader property estimation methods portion it was exploring the instauration of AI. “We were keen to item the inadequacies of facial property estimation, but this accidental was not presented to us, and past the committee was unopen down,” says Tim Cole, an emeritus prof of aesculapian statistic astatine University College London’s Institute of Child Health and erstwhile committee member. Cole describes the look scans arsenic “hideously inaccurate.”

In summation to the interior study and the technological committee members’ concerns, years of trial results from the US National Institute of Standards and Technology person shown that FAE systems’ accuracy often depends connected the contention of the idiosyncratic being analyzed and the prime of the photos taken of them.

“We person rigorous processes successful spot to verify an individual’s property and are moving to modernize these done the investigating of accelerated and effectual facial property estimation technology,” a Home Office spokesperson says successful effect to the findings. The spokesperson adds that the committee was disbanded owed to requiring “different fields of expertise.”

While the Home Office says look scanning is designed to beryllium an “additional” instrumentality for borderline officers and won’t “replace oregon overrule quality judgment,” it did not reply questions astir however it plans to usage the exertion successful real-world environments. “In cases of uncertainty,” the spokesperson says, “individuals volition ever beryllium treated arsenic children until a further appraisal is conducted.”

Expanding Estimates

The UK authorities archetypal announced its plans to usage look property estimation alongside borderline unit judgments to measure migrants successful July 2025. Since then, the Home Office has delayed the rollout of the systems until 2027, saying it volition usage the “cutting-edge AI tech” to “crack down connected fake claims” with the purpose of stopping “adults attempting to crippled the system.”

Over the past 5 years, AI look scans person emerged arsenic a cardinal constituent of arguable online property verification programs, arsenic lawmakers person mandated societal media platforms, porn websites, and immoderate retailers cheque their users’ ages. It has besides been trialled astatine immoderate bars and shops successful the UK. Face property estimation works by analyzing the features of someone’s face—with the underlying systems trained connected millions of age-labeled faces—to nutrient an estimated age. In controlled laboratory tests, the champion algorithms tin foretell a person’s property to wrong astir 2.5 years.

However, the results tin alteration wildly depending connected the algorithm, a person’s gender, demographic details, and different factors. Poor-quality images, specified arsenic those with atrocious lighting, tin drastically trim the show of the systems. (A lawsuit successful point: People person tricked immoderate systems utilizing images of characters from video games.) The Home Office appears to person been alert of imaginable problems with the exertion and inactive pushed up with its program.

The leaked Home Office study produced successful April 2025, which was completed earlier the authorities purchased face-scanning technology, details the investigating of 7 FAE algorithms against much than 2.5 cardinal images. However, the interior study says that the unnamed “best performing algorithm” had “substantial deviations” erstwhile tested connected images of Sub-Saharan Africans. On average, that strategy besides tended to foretell that a 17-year-old would beryllium implicit 18, and it performed worse connected females.

Tens of thousands of radical marque asylum claims successful the UK each year, with galore arriving successful the state aft dangerous, physically demanding journeys successful tiny boats crossing the English Channel. Currently, borderline unit who uncertainty the property of idiosyncratic claiming to beryllium nether 18 tin measure their carnal appearance, answers to interrogation questions, and wide demeanor, to marque an archetypal determination astir their age. These archetypal property estimations are made upon the “first encounter,” the Home Office says successful guidance. Since 2010, 40 percent of radical who person faced property assessments person been classed arsenic adults, according to authoritative statistics.

The leaked Home Office study says that its findings are based chiefly connected investigating that uses high-quality images taken of documented people, and that whitethorn mean that the algorithms’ accuracy rates would beryllium adjacent worse successful practice. The Home Office has indicated that FAE exertion would assistance migration officers who are making property assessments portion moving astatine the constituent of archetypal encounter.

According to the interior report, the fewer photos included successful the investigating information that were taken astatine archetypal encounters were “routinely worse” than follow-up photos of the aforesaid people. The photograph prime was seemingly truthful atrocious that the study was incapable to find if that oregon the carnal information of asylum seekers astatine accomplishment had much of an interaction connected the algorithms’ property estimation results. NIST’s ain investigating has recovered that for galore property estimation algorithms, lower-quality photos typically pb to larger errors. The interior study concluded that much needed to beryllium done to survey the impacts of accent that asylum seekers endure earlier arriving astatine their destination.

“Children seeking asylum person often suffered unimaginable trauma,” says Martha Dark, the co-executive manager of rights radical Foxglove. “They should not beryllium the trial subjects for experimental tech that has baked-in inaccuracy and racist bias.” Foxglove, on with 61 different organizations, sent an unfastened missive to the UK authorities connected Thursday asking for the Home Office to scrap its plans to usage the tool.

It is unclear if the flawed strategy mentioned successful the study was purchased by the UK government, but successful May this twelvemonth it spent much than $400,000 connected face-scanning exertion from German institution Cognitec. (The institution was 1 of the 7 algorithms tested, but it is unclear which.) A WIRED and Lighthouse Reports investigation of nationalist information astir Cognitec’s look property estimation systems recovered that Cognitec’s strategy misclassified doubly arsenic galore 16-year-olds arsenic being 18 oregon older erstwhile the strategy was tested connected a dataset of lower-quality photos taken astatine borderline crossings compared to higher-quality visa photos. The data, from the NIST look estimation scores, besides showed demographic differences successful performance, including that 16-year-olds from West Africa were much apt to beryllium classified arsenic 18 oregon older than Eastern European 16-year-olds.

A spokesperson for Cognitec says they could not remark connected their enactment with the Home Office; however, they constituent retired that “demographic differences” successful show use to each look scanning algorithms. “The reasons for bias are highly analyzable and often related to representation prime issues,” the spokesperson says.

“The bias of Cognitec algorithms is debased compared to different algorithms of akin wide accuracy, and beryllium assured that we are diligently and continuously moving connected reducing bias by processing circumstantial investigating methodologies, designing nonaccomplishment functions successful our web training, and by diversifying the grooming and investigating data,” the spokesperson says.

Stress Test

Even if accuracy tin beryllium improved, exertion is seldom operated precisely however its creators intend. Bugs, method flaws, and idiosyncratic mistake mean systems often nutrient errors. When coupled with delicate decisions that whitethorn alteration people’s lives, those risks tin beryllium exacerbated.

For years, according to erstwhile reports from the UK’s Independent Chief Inspector of Borders and Immigration, the Home Office’s human-led property estimations person included problems. There person been instances of “poor” signaling keeping, “perfunctory” ocular assessments, and astatine times a deficiency of mentation from borderline unit astir existing processes. Staff conducting property assessments were not provided with immoderate circumstantial grooming for the task until 2023, according to the past inspection report.

“Making archetypal property decisions is simply a hard and analyzable job, with migration officers moving successful challenging circumstances, often nether unit to rapidly process tons of caller arrivals,” the Home Office says successful precocious published guidance astir the imaginable usage of look property estimation AI. “It allows migration officers to trial their judgement against the technology’s estimate.”

Yet successful the leaked study from past year, the Home Office said however the look scanning exertion would beryllium utilized successful an “operational context” was inactive being explored. The report, which the authorities antecedently declined to merchandise successful records requests, besides highlights the investigating recovered that “temporary aging” relating to trauma and the “stress of travel” appeared to interaction the accuracy of look property estimation systems, raising further questions astir the usage of the exertion successful the asylum process.

WIRED, Lighthouse Reports, and the Independent asked the Home Office elaborate questions astir however already stretched borderline officers volition interact with facial property estimates, whether unit volition beryllium provided with circumstantial grooming that addresses the weaknesses successful the systems, and if determination volition beryllium circumstantial standards required astir wherever and erstwhile photographs to beryllium utilized successful the strategy volition beryllium taken. We besides asked the Home Office astir immoderate steps it is taking to trim the facial and sex disparities it identified successful the technology.

The Home Office did not straight code these questions but said the UK’s National Physical Laboratory has been commissioned to transportation retired an “independent review” of investigating the systems and looking astatine results of its trials. It has besides publically discussed utilizing a “threshold” age—such arsenic configuring the strategy to place if radical are nether 20—to trim margins of area. It is unclear if this attack volition beryllium taken oregon what immoderate thresholds whitethorn be.

Meanwhile, experts interest that immoderate usage of facial property estimation exertion astatine borders volition beryllium “dehumanizing” for the radical it impacts and could go normalized for staff. “Over clip there's a existent hazard that this volition go entrenched,” says Anna Bacciarelli, a elder researcher astatine Human Rights Watch. “There’s truthful overmuch hazard successful each constituent of this strategy that it’s truly conscionable not worthy pursuing to beryllium capable to accidental that you’re utilizing AI to tackle migration.”
