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 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 “copy-in,” and “replace and restore.”
A method in a computer system for providing a secure display area on a video display device of a video display system, the video display system having video display memory for storing data to be displayed on the video display device, comprising:
A non-transitory computer-readable medium for providing a secure display area on a video display device of a video display system, the video display system having video display memory for storing data to be displayed on the video display device, the computer-readable medium containing instructions that, if executed, will cause a computer system to implement:
