If you need to allow others to access your Ubuntu desktop, you might consider enabling the Guest Session feature. This way, those users don't have access to your data.

Your privacy is important and nearly every Linux distribution is filled with features, tricks, and underpinnings that take the security of your information very seriously. Take, for instance, the idea of the guest session.

The concept is a special login for your operating system that allows others to use the machine, without having access to any of your data. At the same time, no information would be saved between guest sessions. In other words, anyone could use your computer, and -- once they logged out of the guest session -- any and all data collected during the session would be automatically trashed.
