Computer system 800 also includes a main memory 806, such as a random access memory (RAM) or other dynamic storage device, coupled to bus 802 for storing information and instructions to be executed by processor 804. Computer system 800 includes a bus 802 or other communication mechanism for communicating information, and a processor 804 coupled with bus 802 for processing information. 8 is a block diagram that illustrates a computer system 800 upon which the procedures discussed herein may be implemented. When positioning one or more visual watermarks on a screen image, it is generally desirable to position the visual watermarks in an unobtrusive manner so as not to interfere with the information being displayed in the main portion of the screen 208.įIG. In a particular embodiment, one or more visual watermarks may be positioned within the scroll bars 204 and/or 206. Displaying multiple copies of the same visual watermark can be useful if a portion of one or more visual watermarks is blocked by the information displayed in the main portion of the screen 208.

The three visual watermarks 212, 214 and 216 may represent three copies of the same visual watermark. Three other visual watermarks 212, 214 and 216 are positioned horizontally just above horizontal scroll bar 204. A first visual watermark 210 is positioned vertically along the side of vertical scroll bar 206. A pair of scroll bars 204 and 206 allow the user to change the information displayed in a main portion of the screen 208 by scrolling the information horizontally and/or vertically. Screen image 200 includes a menu bar 202 that may contains any number of menu options, menu icons, or other information. 2 illustrates an example screen image 200 containing visual watermarks in different locations.
