 The pcProx-Sonar solves security risks and privacy concerns with unattended computers without requiring additional software or user action. This solution is a presence detector, not a badge reader. When a user steps away from the computer, the product automatically locks the computer. It detects a user’s presence so the computer will not lock until the user physically steps away, avoiding awkward time-out settings.<br /><br />The Sonar easily attaches to the PC via a USB port and is configured as a keyboard. The keyboard allows individual keystrokes and delays to be defined by the user. For example, a Windows® XP equipped system would send a sequence such as Windows “GUI” + “L” to lock the computer when the user walks away.<br /><br /> Applications<br /><br />    * Automatic computer locking, presence detection<br />    * Inactivity monitoring<br />    * HIPAA compliance by protecting sensitive data
