Discord's face scanning age checks 'start of a bigger shift'

But campaigners have said these types of checks are ineffective and could lead to privacy issues.

"Age assurance is becoming the new seatbelt for the internet," said Mr Navarra.

"Will it become the norm in the UK? Honestly, yes, probably."

He said he believed the incoming changes in online safety laws mean online platforms would beef up their age verification processes.

"The era of 'click here to confirm you're 13' is dead," he said.

"Get age verification wrong now, and you don't just lose users - you could lose a courtroom battle or incur fines."

Firms which do not comply with the Online Safety Act could be fined up to 10% of their global turnover.

Instagram previously brought in age checks using facial recognition in 2022 for users who want to change their profile settings to be over 18.

The social media company requires users to take a selfie video on their phone and uses AI to estimate the person's age.

Like Discord, they can alternatively upload a picture of their photo ID.

The US-based platform says the verification - which it describes as "an experiment" - will be a one-time check.

It will apply the first time a user comes across content which it has flagged as sensitive, or if they change their settings on viewing sensitive media.

Users can either use the face scanner or upload a photo of their ID to confirm their age.

It says information used for age checks will not be stored by Discord or the verification company.

Face scans will stay on the device and not be collected, and ID uploads will be deleted after the verification is complete, according to the company.

Content which is flagged as sensitive is already automatically blocked or blurred for teenagers.
