Regulators weren't happy with Facebook collecting and using facial recognition data for EU users. Back in September, Facebook announced that it would delete all existing facial recognition data of EU users. They concurrently announced that they had turned the feature off for new EU users.
The Irish Data Protection Commissioner's office has confirmed that Facebook has deleted all of the data that they said they would. "We recently reviewed the source code and execution process used in the deletion process and can confirm that we were satisfied with the processes used by Facebook to delete the templates in line with its commitment," said Ciara O'Sullivan.
The EU was upset with Facebook over the collecting of facial recognition data without a user's express permission to do so. Facebook has said that they do not currently have plans to turn facial recognition back on in the EU like it has done here in the United States.
