Perhaps understanding the former East German Stasi can also help non-European countries in their effort to understand GDPR - at least, that's what Rob Pegoraro - writing at The Parallax would suggest, whilst cautioning us on government overreach.
"East Germany’s Ministerium für Staatssicherheit—”Ministry for State Security” in English, “Stasi” for short—employed a network of civilian informers to spy on the communications and even inside the residences of its subjects, to enforce conformity with that communist regime. The Stasi Museum, housed in the agency’s former headquarters in the onetime East Berlin, reveals its methods to anyone willing to pay that admission fee." - via Rob Pegoraro - writing at **The Parallax
via Wikipedia: :The Ministry for State Security (German: Ministerium für Staatssicherheit, MfS) or State Security Service (Staatssicherheitsdienst, SSD), commonly known as the Stasi was the official state security service of the German Democratic Republic (East Germany). It has been described as one of the most effective and repressive intelligence and secret police agencies to have ever existed.
And, of course, via Wikipedia, defining the GDPR: The General Data Protection Regulation (EU) 2016/679 ("GDPR") is a regulation in EU law on data protection and privacy for all individuals within the European Union (EU) and the European Economic Area (EEA). It also addresses the export of personal data outside the EU and EEA areas. The GDPR aims primarily to give control to individuals over their personal data and to simplify the regulatory environment for international business by unifying the regulation within the EU.5
