The safest way to do what you want is to create one special user account - in this example let's call it trial.

1. add the user account
2. logon as trail
3. put the script(s) and data files all in the trial home directory.
4. chmod 700 all of the file(s), including the trial home directory itself.

You now have an application that can be run only by the trial user. (or root)

Your users can get to the tiral application one of two ways
1. login as trial
2. su trial -> requires the password for trial account.

It is not that simple. Do you know about PAM or keberos. for example?
Authentication on your system can be complex. If you are creating a 'secure' app, then you need to follow system rules. If you are trying to keep your little brother off the computer then write some that uses the getpass() call.

man getpass has an example.
