The privacy system apparatus and method of the present invention allow users of a publicly accessible terminal to privately access information displayed on a visual monitor of the terminal. In one embodiment, the privacy system 10 is implemented with a terminal 20 having a visual monitor 22 being disposed within a user area 50. The user area 50 provides a space for users 2 to privately access the terminal 20 and is at least partially separated from an external area 30 by a barrier assembly 40. A first filter 60 receives radiation 24 from the visual monitor 22 and transmits linearly polarized radiation 62 into the user area 50. A second filter 44 disposed between the user area 50 and the external area 30 transmits linearly polarized radiation 46. By selecting first and second filters, 60 and 44, respectively, with orthogonal transmission axes, radiation 24 emitted by the visual monitor 22 is substantially blocked from transmission to the external area 30.
