Systems and methods for providing a visible watermark in a remote session

Abstract:

Systems and methods for providing a visible watermark in a remote session. The methods comprise: determining if a graphic update needs to be made at a client computing device during the remote session; generating a first graphic update message in response to a determination that a graphic update is needed; identifying pixels of the graphic which would be affected by at least one watermark if the graphic and watermark were both displayed on a screen of the client computing device; constructing a second string of commands specifying a new color value for each of the pixels that were previously identified; converting the first graphic update message to a second graphic update message by inserting the second string of commands in between a first string of commands and an End-Of-Frame ("EOF") command; and communicating the second graphic update message from the sever to the client computing device.
