New regulations are being introduced that require platforms to create age-appropriate experiences. These include the UK’s Online Safety Act, the EU’s Better Internet for Kids strategy and country-specific Children’s Codes.

Age assurance: What makes for the maturity of a technology or an industry?

Last week, the Australian government decided against the eSafety Commissioner’s recommendation of a pilot before requiring adult sites to verify the ages of visitors. They said this was due to concerns about the privacy of people’s data and the maturity of age assurance technology. So what exactly would constitute a mature technology? Is it something comparable to NASA’s Technology Readiness level? This suggests the technology needs to have gone through a thorough process of research and prototyping, before testing in a live environment and then ultimately rolling it out. If that’s the case, we can say that Yoti and other

Effective facial age estimation: a privacy-preserving approach to age assurance

For platforms to deliver age-appropriate content, they need to know the age of their users. Age estimation technology can provide an inclusive and accessible solution.

Regulators around the world are recognising that more needs to be done to protect children from harmful content online. From the Age Appropriate Design Code and the Digital Services Act to the Online Safety Act and California Age Appropriate Design Code, businesses are being required to have age-appropriate controls in place.
