Optical communication mounting frame in support of secure optical data exchange with stand alone certificate authority

A method comprising:

• placing a first side of an optical communication mounting frame (OCMF) onto a surface of a first device, wherein at least a portion of a first display and a first digital camera that are included in the first device are hidden from view from outside of the OCMF;
• receiving a surface of a second device at a second side of the OCMF, wherein at least a portion of a second display and a second digital camera that are included in the second device are hidden from view from outside of the OCMF, and wherein the portion of the first display is viewable from the second digital camera through a body of the OCMF and wherein the portion of the second display is viewable from the first digital camera through the body of the OCMF;
• while the OCMF is detected as being present between the first and second devices, allowing optical communications between the first and second devices by displaying a first set of data on the first display and reading the first set of data using the second digital camera and displaying a second set of data on the second display and reading the second set of data using the first digital camera;
• and
• inhibiting the communication between the first and second devices in response to detection that the OCMF is absent from a space between the first and second devices.
