A user-customizable information management solution, providing protection (e.g., privacy and/or security protection) for displayed information that may reduce or prevent exposure of sensitive and/or confidential information. In one aspect, a viewing aperture is controlled by the user and provides a view of a subset of the information displayed, where information not within the aperture is blocked or obscured to eliminate or reduce viewability. Optionally, simultaneous use of more than one viewing aperture may be supported. In another aspect, predefined information management instructions are used for determining how to protect a portion or portions of a document. The instructions may specify particular text and/or graphics categories defined by the user as being sensitive. Portions of the document that contain corresponding text and graphics are located, using a software-based search, and are blocked or obscured according to the predefined instructions. Dynamic tuning may be supported, whereby the user dynamically selects additional text/graphics for protecting.
