Audio Signal Analysis for Privacy Breach Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During phone conversations, participants often unknowingly expose sensitive information due to unawareness of the audio status of the other party, as they may be using external speakers or speaking from a distance, leading to unintended listeners.
Innovation Solution
A system and method that analyze audio signals to determine the audio input/output configuration of remote communication devices, providing real-time indications of potential privacy breaches, allowing participants to adjust their conversation accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audio signal analysis is performed to detect privacy breaches, then privacy protection capability is improved, but device complexity increases
Solution Approach 1:
The patent introduces an analysis application as an intermediary component that mediates between the audio processing system and the privacy detection function. This application analyzes audio signals to determine audio input/output configuration without requiring deep integration into the core device architecture, thereby improving privacy protection capability while minimizing the increase in device complexity through a modular, non-intrusive approach
2Measurement precision
If real-time audio configuration monitoring is implemented, then privacy breach detection accuracy is improved, but processing time increases
Solution Approach 1:
The system performs preliminary analysis of audio configuration status by continuously monitoring audio input/output configuration changes. By maintaining awareness of the current audio configuration state in advance, the system can quickly determine whether a privacy breach has occurred without requiring extensive processing time when a breach detection is needed, thus improving detection accuracy while minimizing time loss
Data Source
AI summary
A method of identifying a breach in privacy during a communication session, including communicating with a remote communication device using a local communication device, analyzing an audio signal from the remote communication device to identify an audio input/output configuration of the remote communication device, determining from the audio input/output configuration if a breach in privacy is signified.
