Padlock is an extremely robust 'application security' solution that allows pre-specified applications to be used by only those with the secure password.
Padlock enables controlled use of your computer by all. You can remain confident that any applications that might be used to access sensitive, confidential or compromising data are safe from use and/or prying eyes.

You don't need extra software get this sort of functionality from MacOS X. Simply set up restricted accounts for users and you can determine which programs they can access.
You can do this in the Accounts section of System Preferences (accessible under the apple menu)
In the Security section of the System Preferences you can also set automatic logout after a period of inactivity.
Hope someone finds this informative.
