Meta has been ordered to stop training its AI on Brazilian personal data.

Brazilian Data Protection Authority (ANPD) Meta banned from training its AI models on Brazilian personal data, citing “risks of serious harm and hardship to users.” The decision follows Meta privacy policy update in May in which the social media giant granted itself permission to exploit public Facebook, Messenger and Instagram data from Brazil — including posts, images and captions — to train artificial intelligence.

This decision is a consequence a report published by Human Rights Watch last month, in which LAION-5B — one of the largest photo caption datasets used to train AI models — was discovered to contain personal, identifiable photos of Brazilian children, putting them at risk for being used in deepfakes and other forms of exploitation.

As reported Press AssociationThe ANPD told the country’s official newspaper that the policy carries an “imminent risk of serious and irreversible or difficult-to-repair damage to the fundamental rights” of Brazilian users. The region is one of Meta’s largest markets, with 102 million Brazilian user accounts found on Facebook alone, according to the ANPD. notification published by the agency on Tuesday gives Meta five business days to comply with the order or face a daily fine of 50,000 reais (about $8,808).

Meta said in a statement to AP that the updated policy “is in line with Brazilian privacy laws and regulations” and that the ruling is “a step back for innovation, competition in AI development, and further delays in delivering AI benefits to people in Brazil.” While Meta says users can opt out of having their data used to train AI, ANPD says there are “excessive and unjustified barriers” that make it arduous to do so.

Meta has faced similar pushback from regulators in the EU, which has caused the company to halt plans to train its AI models on European Facebook and Instagram posts. Meta’s updated data collection rules are already in force in the USAwhich, however, lacks comparable protection for user privacy.
