Amid lawsuits alleging child safety concerns, online gaming service Roblox is expanding its age-estimation technology to all users and partnering with the International Age Rating Coalition (IARC) to provide age and content ratings for the games and apps on its platform. This involves scanning users’ selfies and analyzing facial features to estimate age. This age-estimation tech is combined with other systems, including ID age verification and verified parental consent, to provide a more accurate measure of a user’s age, Roblox says — especially when compared with simply having kids type in a birth year when they create an account. The company notes that it’s also planning to launch systems that will further limit communications between adults and minors on its platform. Meanwhile, the company’s partnership with IARC will see Roblox replacing its own content and maturity labels with those used by rating agencies worldwide. That means users in the U.S. will see ratings from the ESRB, while other countries will see those used by their own ratings authorities. Players in the Republic of Korea will see ratings from GRAC; players in Germany will see ratings from the USK; and players elsewhere in Europe and the United Kingdom will see ratings from the PEGI, for instance. This system is meant to help parents better understand what sort of games their kids are playing, based on factors that could raise concerns. Among its tools is Roblox Sentinel, an open source AI system designed to detect early signals of child endangerment. The company also offers parental controls, tools to restrict communications, and technology that detects when there are servers where a large number of users are breaking its rules, so it can take them down.
