This is all correspondence between junior minister at the Department of Health Jim Daly and other organisations about his plan to link social media accounts to official forms of identity like passports or public services cards.
The plan has already been rejected by Taoiseach Leo Varadkar but Mr Daly does not appear to have given up on it.
The documents show that Minister Daly wrote personally to Mark Zuckerberg of Facebook about his idea for an “online verification code” and subsequently received a response from the company.
Facebook said it would raise “some very difficult privacy and data protection-related issues” but were happy to meet with him. That meeting took place on February 14, but the minutes of it would not have been subject to this FOI request.
