"AI for Age Verification": A Solution or a New "Checkpoint"?—The Reality Surrounding Australia's <16 Prohibition on Social Media

The final report of the large-scale trial conducted by the Australian government (Age Assurance Technology Trial) has been released, concluding that "age assurance" (a series of mechanisms for estimating, verifying, and consenting to age) can be implemented with a certain level of effectiveness while protecting privacy. However, it is not a "panacea," and each method has its own accuracy, bias, and practical challenges—such a nuanced evaluation. The government plans to implement a policy in December 2025 to ban social media use for those under 16, and platforms must take "reasonable measures" or face fines of up to 49.5 million AUD.infrastructure.gov.auReuters


What Was Indicated: Key Points of the Report

The report evaluates a combination of multiple methods such as age verification (strict verification with official IDs), age estimation (AI estimating age from selfie images), age inference (probability estimation from behavioral data), continuous validation, and parental consent and control. The summary concludes that "there is no one-size-fits-all solution," and the privacy burden, implementation difficulty, and bias differ depending on the method. Particularly, a "gray zone" was pointed out where misjudgments increase near the threshold of 16 years old.infrastructure.gov.auABC


The Barrier of "Misjudgment" in Numbers

While selfie-based age estimation is considered fast and privacy-friendly, its instability near the threshold is a challenge. The government-commissioned evaluation reported that the probability of a 16-year-old being misjudged as "under" is about 8.5%. Additionally, another test showed that a specific provider's model overestimated 34% of 14-year-olds and 73% of 15-year-olds as "16 and over", indicating that underage users could slip through depending on the implementation design.ReutersThe Guardian


Bias and Privacy: The "Landmines" of Practice

The evaluation pointed out a tendency for larger errors among non-white, female, and older age groups. Some businesses have resorted to excessive data collection and unnecessary storage, with a tone that "privacy can be protected but constant monitoring is necessary." External technology media also reported a tendency for some providers to overinterpret regulatory requirements and fall into over-collection.ReutersTechExplore


What Happens When Implemented

  • Remedy for Misjudgment: The government promises an appeal process for users mistakenly excluded. However, there is also a view that the delay in response by large platforms is a challenge.The Guardian

  • ID Presentation or Alternative Means: Scenarios requiring official IDs like passports may disadvantage those without IDs or marginalized communities. While age inference based on behavioral data is less invasive, it poses implementation challenges for small services, risking withdrawal. Reports mentioning "withdrawal examples" in the Americas suggest that market exit of small services could narrow domestic users' choices.The Guardian

  • Pressure from Fines: The fine cap of 49.5 million AUD is a very strong incentive, potentially forcing large companies towards multi-layered defense (estimation + ID + parental consent), while small companies may face a choice between using outsourced services or withdrawing.Reuters


Reactions on Social Media are Polarized

  • Concerns from Digital Rights Advocates: Criticisms include "normalization of misjudgment, bias, and expansion of biometric data collection." Green Party Senator David Shoebridge also argues that it is "disadvantageous to women and people of color, posing significant privacy risks." Citizen group Digital Rights Watch demands ongoing transparency and oversight.X (formerly Twitter)

  • Voices of Irony and Opposition: Pirate Party Australia responds with satire, suggesting a "ban for everyone under 160 years old". Practitioners and journalists see the "trial results as rather 'unfavorable for the ban'."X (formerly Twitter)

  • Industry's Positive Outlook: Organizations like the **Age Verification Providers Association (AVPA)** emphasize that "privacy-protective implementation is possible." Academic and media circles also offer a moderate evaluation, stating that "while there is no single solution, implementation is possible."X (formerly Twitter)X (formerly Twitter)


Practical Roadmap: What to Prepare

  • Platforms: To address misjudgments near the threshold, implement multi-factor integration (AI estimation + risk-based review + parental consent/ID fallback). Regulate minimization of audit logs and shortening of retention periods.infrastructure.gov.au

  • Schools and Parents: Immediately after implementation, there may be access instability (misblocking or mispassing). Strengthen digital literacy education and share with children the appeal procedures and safe methods for presenting IDs.The Guardian

  • Policy Authorities: Publish technical specifications, transparency indicators, and audit procedures early. Regularly publish and correct misjudgment rates for minorities and KPI for complaint handling.Reuters


Timeline Overview

  • December 2024: Related amendment law (Online Safety Amendment) is enacted. Implementation is scheduled for December 2025.Wikipedia

  • September 2025: Final report of the Age Assurance Technology Trial. The government states that "effective and efficient implementation is possible," while acknowledging uncertainties around the threshold and bias.infrastructure.gov.auReuters


Conclusion: Strengthen Protection or Erode Freedom

Australia's age assurance is a "dynamic system" balancing children's safety and citizens' freedom and privacy. Technology can be either a remedy or a poison depending on its use. The keys to success are: ① a multi-layered and reversible design (recoverable from misjudgments), ② minimal data collection and short-term storage, ③ transparency in misjudgment and complaint handling, and ④ implementation support for small businesses. With little time left until implementation, the final question is whether the "technology to protect children" will infringe on the rights of both children and adults—ultimately, it's not the technology but operation and oversight that will be tested.ReutersTechExplore
