There's a set of science fiction novels written by Robert Sawyer, the
Neanderthal Parallax, that supposes an alternate reality where neanderthals survived instead of homo sapiens and their society developed without considerations for privacy. Every second of every day of the neanderthals' lives is recorded and kept in a public depository which is protected and cannot be tampered with. The theory the author presents is that if the everyone is monitored, from the high school dropout pumping gas all the way up to the highest ranking government or business authority, 24/7, and the recording technology is automatic and cannot be tampered with (what I find the hardest to swallow), taking advantage of what would otherwise be private information would become nearly irrelevant. In other words, it would level the lack-of-privacy playing field.
Mind you, this is all quite fantastic and clearly unrealistic, but it does make one wonder.
