Explanation
A privacy filter is a physical panel placed over a monitor screen that uses micro-louver technology to drastically narrow the viewing angle. Only the user sitting directly in front of the screen can see the content; anyone viewing from the side sees a blank or darkened screen. This directly prevents visual eavesdropping (shoulder surfing). Anti-virus software (A) protects against malware, not visual observation. A key fob (B) is a two-factor authentication token for system access. A biometric device (C) is used for identity authentication-none of these prevent someone from looking at the screen.
