If the Integritetsskyddsmyndigheten (IMY) decides on sanctions, the cost for public activities may be up to ten million kronor, reports Sveriges Radios Ekot.
For companies, it's about up to 20 million euro, or 4 percent of the global annual turnover, depending on which is greater, says Olle Pettersson, lawyer at IMY to the radio.
At the same time, IT security expert Anne-Marie Eklund Löwinder emphasizes that the heaviest cost is another.
No sanctions in the world will be able to repair the damage that many people have suffered. When it comes to public administration, I think that what will cost the most is lost confidence, she says.
