Abstract: A portable computing device captures imagery from a screen of a second computer, decodes information steganographically-encoded in the screen display, and uses the decoded information to establish a secure session with the second computer. Such technology enables a help-desk staffer to interact with a client's desktop computer, without touching the keyboard of the desktop computer, and without interrupting the client's work. A great many other features and arrangements are also detailed.
