Hiding a Worksheet w/a Password?

Hello Friends,

I have a shared workbook and have locked down the cells that shouldn't be changed by other users but I also have sensitive data that I don't want to have to put on a separate file. Is there a way to password protect (or some other means) so that if the user clicks the tab, it tells them "you're not allowed to view this tab" (or something to that effect)?

Many thanks in advance!
