Tog is a name I had forgotten. Their metaphor for personal privacy and security has stuck with me for a long time. Not to say that I think this metaphor is perfect, just that it has stuck with me. They described a medieval city as your personal information. Untrusted traders have to hawk their wares outside the city walls. More trustworthy apps and services are allowed inside the city walls, but have no access to the castle keep. Family and highly trusted entities are permitted entry to the castle keep. I've always liked the way that fairly neatly illustrated layers of security and privacy.
