United Kingdom, April 15 -- Roblox has defended a major overhaul of its child safety systems.

It comes after parents raised concerns that its age-estimation technology could misclassify children and expose them to less restricted versions of the service.

The platform, which says it has 144 million daily users worldwide, is introducing age-specific account types - Roblox Kids and Roblox Select - designed to tailor content, communication features and access based on a user's estimated age.

Its system, which includes facial analysis, is already used by more than half of users.

Parents, however, told BBC News children have been incorrectly identified as adults during checks, reducing parental controls and safeguards.
