Abstract
A method and apparatus prevent eavesdropping via a computer by detecting and alerting if more than one authorized driver is controlling a interface circuit that is providing audio or video input information. Further, prevention is performed by detecting and alerting if more than one authorized application programming interface is receiving audio or video input information from an authorized driver. Also, prevention is performed by detecting and alerting if more than one authorized software application is receiving audio or video input information from an authorized driver. In addition, prevention is performed by detecting and alerting upon first receipt of audio or visual information by an authorized software application via an authorized application programming interface and authorized driver.
