Abstract
Demonstration (demo) application software and various utility software programs are configured as a novel 'protected demonstration environment' having layered security mechanisms for protecting the integrity of software executing on a computer. The security mechanisms include an underlying activity timer for ensuring that the demo program is periodically running in the absence of user input activity. When the demo program is not running, additional security mechanisms, such as message filters and icon disablers, are provided to reduce the vulnerability of the system. These security mechanisms cooperate to provide users access to certain innocuous features of the software through a graphical desktop interface on a computer screen, while preventing access to potentially destructive features.
