A newly published paper provides a detailed evaluation of age assurance technologies (AAT) used to protect minors online. The authors examine different approaches including age verification, age estimation, age inference, and parental control and consent, along with architectures such as online, offline device-based, and offline credential-based systems. They assess these combinations for effectiveness, side effects, and user acceptance, noting that all methods can be circumvented and often raise concerns around privacy, anonymity, bias, discrimination, exclusion, and censorship. The study, available at https://arxiv.org/abs/2603.25695, concludes with recommendations for which types of AAT better balance protection for minors against unwanted side effects.
