Timed Password Example

This is example shows how control access to a CD within a range of dates.

Before a start date, access is prohibited. In the first time period after the start date, access is controlled by a initial password. The initial password expires at the end of the first period and the user is instructed to ask for an extension password from their supplier. At the end of the second period, all access is prohibited.

The possibility of the user cheating by modifying the dates on their computer is also caught.

The page "secured.htm" is password protected. To view this page, you need an appropriate password. If you view the page without the password, it is unintelligible - to prove the point, try viewing it here : secured.htm

Enter your password :
