Data And Goliath

Surveillance technologies create assymetries, individuals trading freedom for convenience. Lots of worries in this book, take home message: minimize large transactions, use cash, turn off your cell phone, travel with borrowed/rented equipment.
Encryption can be strong, but it rests on vulnerable, exploitable platforms and weak endpoints. If everyone encrypts, surveillance becomes a lot more expensive. But so does all that encrypting, which I don't have enough time for.
Lots more in the book.
