Creating Invisible Sheets w/ Password

[Lunnmb]

Scenario: Project is in evaluation stage, Excel Workbook is posted to shared drive. There are 4 Sheets in the workbook, each of which is an evaluator's marking layout. To keep evaluator's from seeing each others scores I would like to make each sheet invisible. Each evaluator will be given a password and they can then unlock only their own worksheet and edit it. When the document is saved the sheet will return to being invisible again.

Is it possible to create this with a Macro/ VBA code?
