A European Union (EU) regulator imposed a fine of 345 million euros on TikTok this Friday for failing to comply with data protection rules for minors, the latest in a series of sanctions against the technology giants.   Chinese-owned TikTok Technology Limited will have to pay "administrative fines totaling 345 million euros" (about $368 million) and adjust its operations to comply with the rules within three months, the Protection Commission announced. of Irish Data (CPD) in a statement replicated by the AFP news agency.   This Irish regulatory body - which has a central role in ensuring compliance with EU rules - opened an investigation in September 2021 into the practices of this social network, a subsidiary of the Chinese giant ByteDance.   TikTok has 134 million users in the EU and this investigation includes practices between July 31 and December 31, 2020. The regulator explained that the registration of minors under 18 years of age on the social network was done in a way that defined By default the accounts are public.   Another problem detected by the agency is that a TikTok feature called "family connection", which allows a teenager's account to be linked to that of their parent, did not include adequate verification of affiliation.   The regulatory authority analyzed the social network's verification steps to prevent the registration of minors under 13 years of age and did not find any violations, but noted that the platform does not adequately evaluate the risks faced by children.
