DETECTION OF POTENTIAL EXFILTRATION OF AUDIO DATA FROM DIGITAL ASSISTANT APPLICATIONS

摘要

The present disclosure is generally related to a data processing system to detect potential exfiltration of audio data by agent applications can include a data processing system. The data processing system can identify, from an I/O record, an input received from the digital assistant application via a microphone of a client device, an output received from the agent application after the input, and a microphone status for the microphone. The data processing system can determine that the output is terminal based on the input and the output. The data processing system can identify the microphone status as in the enabled state subsequent to the input. The data processing system can determine that the agent application is unauthorized to access audio data acquired via the microphone of the client device based on determining that the output is terminal and identifying the microphone status as enabled.
