YouTube is rolling out age-estimation technology in the U.S. to identify teen users in order to provide a more age-appropriate experience. TechCrunch reports: When YouTube identifies a user as a teen, it introduces new protections and experiences, which include disabling personalized advertising, safeguards that limit repetitive viewing of certain types of content, and enabling digital well-being tools such as screen time and bedtime reminders, among others. These protections already exist on YouTube, but have only been applied to those who verified themselves as teens, not those who may have withheld their real age. [...] If the new system incorrectly identifies a user as under 18 when they are not, YouTube says the user will be given the option to verify their age with a credit card, government ID, or selfie. Only users who have been directly verified through this method or whose age has been inferred to be over 18 will be able to view the age-restricted content on the platform. The machine learning-powered technology will begin to roll out over the next few weeks to a small set of U.S. users and will then be monitored before rolling out more widely, the company says. [...] YouTube isn't sharing specifics about the signals it's using to infer a user's age, but notes that it will look at some data like the YouTube activity and the longevity of a user's account to make a determination if the user is under 18. The new system will apply only to signed-in users, as signed-out users already cannot access age-restricted content, and will be available across platforms, including web, mobile, and connected TV.Read more of this story at Slashdot.
