Acoustic side-channel attacks, where sensitive information like passwords is inferred from device sounds, are a growing cybersecurity threat. Research shows AI can accurately decipher typed content just by listening to keystrokes, posing risks in environments with active microphones (e.g., video calls). Current defenses are either impractical or non-existent for everyday users.
One way to address this could be a dual-pronged software solution:
The tool could run unobtrusively, require minimal interaction, and adapt to different environments (quiet offices vs. noisy cafes). Potential users include remote workers, enterprises with compliance needs, and cybersecurity professionals auditing systems.
An MVP might start with a noise-masking tool tested against known attack models, later expanding to detection features and user-friendly alerts. Key advantages over existing solutions include:
Compared to hardware like silent keyboards, this approach is cheaper, works with existing devices, and covers non-keyboard inputs (e.g., touchscreen taps).
Potential revenue streams include freemium models (basic protection free, advanced features paid) or enterprise licensing. Challenges like false alarms or call quality disruption could be addressed with adjustable masking levels and local audio processing to ensure privacy.
This approach could fill a critical gap by providing accessible, software-based defense against an underaddressed threat.
