Abstract

Apparatuses and methods of the present invention provide improved control over the activation and deactivation of a computer program. For example, the computer program may be a screen saver program and/or a password protection program. The computer program is prevented from being activated when the user has not recently provided input to a computer system via an input-output device, but the user is still in the vicinity of the computer system. When no person is detected in the vicinity, the present invention allows the computer program's activation to be controlled using standard known methods. In one embodiment, the present invention provides enhanced screen saver activation and deactivation control without the need to modify existing computer hardware or software. Embodiments of modified computer hardware and software systems are also provided where it is desirable to integrate enhanced screen saver activation and deactivation control into a hardware or software system. Other aspects of the present invention deal with program activation control, user authentication, and methods for providing the most economical implementations.
