Within the ambit of Meta’s landmark legal settlement concerning child safety, no single category imposes more exacting stipulations than its undertakings on age assurance — and this is entirely justified.

However efficacious those protective measures may prove, they remain fundamentally ineffectual if Meta cannot ascertain which of its users are minors.

Ascertaining which accounts belong to minors constitutes the pivotal cornerstone of the child-safety protocols that corporations such as Google, TikTok, and Roblox are intensifying, as public and regulatory opprobrium mounts against them across the United States and beyond.

The Meta settlement — with protections the company says could become industry standards — will afford the social media giant a twelvemonth to refine its methodology.

Yet the available avenues remain circumscribed, and enhancing age-verification technology poses formidable hurdles, not least navigating the privacy ramifications not solely for minors but also for adults who may be compelled to demonstrate their majority.

The $18 billion settlement resolves claims brought by state attorneys general that the company deliberately engineered its Instagram and Facebook platforms to captivate young users’ attention, thereby harming their mental health.

The agreement, announced last week with the Menlo Park, California-based firm, encompasses 48 states, the District of Columbia, and U.S. territories.

In the offline world, individuals rely on government-issued identification to substantiate their age—whether exceeding 18 or 21—for entry into establishments such as clubs or the purchase of tobacco products.

Although this mechanism functions in principle within the digital realm, a considerable number of people harbor reservations about entrusting a major technology corporation, such as Meta or Google, with access to their driver’s license or passport.

Meta accepts government-issued identification to ascertain users’ ages, with a commitment to expunge such data within a 30-day window.

Beyond reliance on official documents, however, an increasing cohort of technology enterprises is deploying artificial intelligence in an attempt to infer users’ ages.

This practice does not constitute genuine age verification.

Although AI can estimate an individual’s age—frequently with considerable accuracy—it remains incapable of substantiating a person’s actual date of birth.

In the preceding year, Google instituted an age-assurance framework for YouTube that leverages artificial intelligence to discern between adults and minors based on their viewing patterns; Meta has likewise adopted a comparable strategy.

AI-driven age verification systems infer an individual's age from behavioral and contextual indicators.

On Instagram, this encompasses "contextual clues" such as posts pertaining to birthday festivities or scholastic milestones, alongside engagement patterns—including which content users like, comment on, or dwell upon—their social networks, and the temporal rhythms of their login activity.

For example, an individual who remains offline during conventional school hours would likely be classified as of school age.

In a blog post published last year, Meta articulated that its artificial intelligence also scrutinizes photographs uploaded by users for visual indicators, including “height or bone structure, to estimate someone’s general age; it does not identify the specific person in the image.”

By synthesizing these visual insights with our examination of textual content and user interactions, we can substantially augment the volume of underage accounts we detect and subsequently expunge, the company elaborated.

Pursuant to the settlement, Meta has committed to augmenting its age-verification mechanisms through a combination of proprietary and third-party technologies, subject to periodic independent audits assessing their efficacy.

The accord further delineates explicit benchmarks concerning false-positive rates—namely, instances in which minors are erroneously classified as adults.

Moreover, should a user be identified as under the age of thirteen and consequently be expelled from any of its platforms, Meta is obligated to undertake age-verification procedures for that individual's network of associates as well.

Identity verification enterprises such as Yoti and Persona, which collaborate with technology conglomerates including Meta and Roblox, employ the video selfies that users upload in order to ascertain their ages.

The gaming platform Roblox, which, in contradistinction to social media platforms, permits children under the age of thirteen to register, mandates that players submit a video selfie for the purpose of age estimation.

Roblox asserts that these videos are expunged upon completion of the age verification process.

Users are not compelled to undergo a facial scan to access the platform; such a requirement applies solely to those wishing to engage in chat functions with fellow users.

A subset of users have documented discrepancies, while certain experts have voiced reservations regarding the dependability of facial age estimation technologies, particularly when applied to women or specific racial and ethnic demographics.

Nevertheless, Matt Kaufman, chief safety officer at Roblox, asserted last year that for individuals aged approximately five to twenty-five, the system is capable of estimating their age with a margin of error of one to two years.

Certain websites and social media conglomerates, notably Meta, have contended that age verification ought to fall within the purview of app store operators, such as Apple and Google, rather than individual platforms.

This arrangement would necessitate that app stores authenticate the ages of their users prior to granting them access to application downloads.

Unsurprisingly, Apple and Google hold a contrary position.

Lauded by its proponents, including Meta, as ostensibly ‘simple,’ this proposal conspicuously omits coverage for desktop computers and other devices typically shared within households.

Moreover, it may prove ineffectual against pre-installed applications,” Google asserted in a blog post last year.

Age verification protocols are ostensibly designed to preclude minors from accessing online environments deemed unsafe or unsuitable for their developmental stage, whether these constitute social media platforms or adult-oriented websites.

Yet detractors of such digital age-gating discern an alarming trajectory toward an internet characterized by diminished security, eroded privacy, and curtailed liberty—one in which individuals may find themselves barred not merely from pornographic content, but also from news, health-related information, and the capacity for candid, anonymous discourse.

The determination of what constitutes harm to minors is inherently subjective, and it is precisely this ambiguity that legal scholars contend renders age-verification mandates susceptible to conflict with the First Amendment.

Such a requirement could conceivably compel individuals to authenticate their age before accessing virtually any digital content, from streaming platforms like Netflix to hyper-local community forums.

The digital rights advocacy group Electronic Frontier Foundation has, for years, persistently cautioned against the practice of "age-gating the internet."

“Irrespective of the methodology employed, every system necessitates that users divulge sensitive and immutable personal data, thereby inextricably linking their offline identity to their online conduct,” the EFF asserts in a blog post.

“Once such invaluable information has been amassed, it remains perpetually susceptible to exfiltration, cyber intrusion, or nefarious exploitation.”
