After talking with the maintainer of sqlcipher, I'm now using the v2beta branch, which provides an sqlcipher_export function, making my life much easier. I'm exposing this function to python-sqlcipher (the bindings), and then making use of it within Zeitgeist. Basically, this allows us to attach an unencrypted db to an encrypted db with a simple subroutine call, rather than having to specify the entire schema manually. Someone could start packaging this, I believe that most of the packaging for sqlcipher has been done.

While someone may happen to use an encrypted disk, Zeitgeist may serve as the ultimate accidental spyware to an unsuspecting user. One possible mitigation is to randomly generate a reasonable key, tie it into the login keychain and then use that key with something like http://sqlcipher.net/ rather than straight sqlite. In theory, a user will never know that this encryption/decryption is happening - no underlying assumptions about the disk need to be made to maintain any security guarantees. This should prevent anyone from learning the contents of the database without also learning the login password. Modern Ubuntu machines disallow non-root ptracing ( https://wiki.ubuntu.com/SecurityTeam/Roadmap/KernelHardening#ptrace ) and if the gnome keyring is locked, an attacker would have a much harder time grabbing meaningful Zeitgeist data without interacting with the user or bruteforcing the login keychain.
