David Brin's "Kiln People" is set in a highly transparent world, and I think it started me thinking about how I shouldn't trust the future to keep anything private
Synopsis on Wikipedia:
In the near future, a journalist observes how the world, his daughter, and he himself are affected by "Remem", a form of lifelogging whose advanced search algorithms effectively grant its users eidetic memory of everything that ever happened to them, and the ability to perfectly and objectively share those memories. In a parallel narrative strand, a Tiv man is one of the first of his people to learn to read and write, and discovers that this may not be compatible with oral tradition.
It's more of a backdrop than a key focus, but the Culture series by Iain Banks features a civilisation where AI minds can monitor everything on their spaceships and habitats to near perfection. The only thing they choose not to monitor (usually), despite being able to is the thoughts of biological lifeforms.
