Question

Options

BCommon access card

Explanation

A privacy screen (also called a privacy filter) is a physical overlay placed on a monitor or laptop screen that uses micro-louver technology to drastically narrow the viewing angle. Only the person sitting directly in front of the screen can see the content clearly; anyone viewing from the side sees a darkened or blank screen. This directly addresses visual eavesdropping (shoulder surfing) in high-traffic areas - exactly Ann's concern. A biometric device (A) and common access card (B) control physical access authentication but do not block visual data exposure. A cable lock (C) prevents device theft but does not restrict screen visibility. A mantrap (E) is a physical access control vestibule for entry/exit control into secure areas, not a solution for screen privacy at a workstation.
