Abstract
Masking JavaScript in an embedded browser of an application display identifies areas within the embedded browser that are to be masked to a screensharing client, to enable the screensharing client to redact corresponding regions of the application display when the application display is transmitted on a screenshare session. A list of CSS selectors is provided to the masking script identifying HTML elements in the DOM that are to be masked. The masking script determines the locations and sizes of the HTML elements within the embedded browser and reports the masked areas to a screensharing client. The screensharing client correlates the masked areas within the embedded browser to regions of the application display containing the embedded browser. The screensharing client redacts the correlated regions from the screensharing data and does not transmit the redacted regions to prevent information appearing in the redacted regions from being transmitted on the screenshare session.
