Recent research has highlighted the significant usage of social media among children in Australia. 80% of children aged 8-12, equating to approximately 1.3 million youngsters, use one or more social media platforms. This underscores the potential for widespread breaches of current minimum age policies. Age-assurance technologies, which verify, estimate, or infer users' ages, are considered vital tools for regulators and digital platforms seeking to safeguard online environments. Incode Technologies utilises a biometric solution where a user's age is estimated from a selfie within seconds, without storing personal information, achieving a 99.87% true positive rate. The entire verification process is completed in approximately three seconds on average and has shown high accuracy in estimating the age of minors between 6 and 17 years old.
