Methods and systems for enhancing the security of data during input and output on a client computer system are provided to prevent attempts by unauthorized code to access, intercept, and/or modify data. Example embodiments provide a plurality of obfuscation techniques and security enhanced drivers that use these obfuscation techniques to prohibit unauthorized viewing/receiving of valid data. When the drivers are used together with the various obfuscation techniques, the security enhanced drivers provide mechanisms for 'scheduling' the content of the storage areas used to store the data so that valid data is not available to unauthorized recipients. When unauthorized recipients attempt to access the 'data,' they perceive or receive obfuscated data. The obfuscation techniques described include &#x201c;copy-in,&#x201d; &#x201c;replace and restore,&#x201d; and &#x201c;in-place replacement&#x201d; de-obfuscation/re-obfuscation techniques. In one embodiment, a security enhanced display driver, a security enhanced mouse driver, a security enhanced keyboard driver, and a security enhanced audio driver are provided. To complement the security enhancements, the methods and systems also provide for a watchdog mechanism to ensure that the driver is functioning as it should be and various user interface techniques for denoting security on a display device.

An alternate display content controller provides a technique for controlling a video display separately from and in addition to the content displayed on the operating system display surface. Where the display is a computer monitor, the alternate display content controller interacts with the computer utility operating system and hardware drivers to control allocation of display space and create and control one or more parallel graphical user interfaces adjacent the operating system desktop. An alternate display content controller may be incorporated in either hardware or software. As software, an alternate display content controller may be an application running on the computer operating system, or may include an operating system kernel of varying complexity ranging from dependent on the utility operating system for hardware system services to a parallel system independent of the utility operating system and capable of supporting dedicated applications. The alternate display content controller may also include content and operating software delivered over the internet or any other LAN. The alternate display content controller may also be included in a television decoder/settop box to permit two or more parallel graphical user interfaces to be displayed simultaneously.

A fuzzy logic load management controller for use with a computer image generator. The load management controller is used use with a computer image generator having a plurality of inputs and a plurality of outputs, and includes an adder that couples inputs to the image generator. The load management controller comprises a fuzzy logic controller disposed in a feedback loop between the output of the image generator and the adder. The load management controller includes a fuzzy logic inference engine, a set of membership functions coupled to the inference engine, and a rules database coupled to the inference engine that includes a set of if-then rules that specify the response of the fuzzy logic controller to inputs applied thereto. The fuzzy logic controller provides for load management of the image generator that gracefully degrades a viewed scene, keeps the image update rate constant, and renders important objects in the viewed scene.
