Abstract: In one aspect, an example methodology implementing the disclosed techniques can include, by a computing device, receiving input events from a remote computing device, ones of the input events having an input event position associated with a position on a screen of the computing device being shared during a screen sharing session and, responsive to a determination that a first input event position of a first one of the input events is within a protected region of the shared screen, preventing the first one of the input events from being applied to the shared screen. The method can also include, by the computing device, responsive to a determination that a second input event position of a second one of the input events is not within the protected region of the shared screen, applying the second one of the input events to the shared screen.

Abstract: A technique for securely rendering content downloaded over a network includes parsing a downloaded web page into a DOM (Document Object Model) tree and splitting the DOM tree into multiple DOM instances, where each DOM instance is dedicated to a respective type of web content. The technique processes each DOM instance using a respective render engine, which implements the security policy on the respective type of web content by blocking or altering content, and/or by limiting functionality that may be used in connection with the content.
