Apple refuses to unlock the encryption on a phone used by a terrorist. A hospital pays a bitcoin ransom to get its computer system returned by cyber-hijackers. I understand the concept of encryption, but I couldn’t tell you how it works. Not only can’t I tell you how bitcoins work, I can’t even explain the concept. What I do know is that these new technologies have been co-opted by terrorists and criminals, allowing them to operate in a virtual world that is invisible to governments. So, how much is your privacy worth? The cost seems to go up every day.
