Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a system that prevents the misappropriation of audio signals, such as audio passwords and personal data, which are often recorded and unauthorizedly used.
Innovation Solution
A real-time audio cryptology system that uses a cryptographic device to generate and emit a dynamically varying continuous audio tone inaudible to users but audible to recording devices, mixing with audio signals to alter their characteristics and prevent unauthorized recording, and includes a frequency selection and monitoring mechanism to adapt the tone frequency over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a continuous audio tone is generated to prevent misappropriation of audio signals, then audio security is improved, but the system complexity increases
Solution Approach 1:
The patent employs parameter changes by dynamically varying the frequency of the audio tone over time. The system selects different frequencies from a predefined set and changes them at specific time intervals, making the audio signal unpredictable and difficult to capture or replay. This frequency modulation approach enhances security without requiring complex cryptographic algorithms or hardware.
2Reliability
If the audio tone frequency is dynamically varied over time, then security against replay attacks is improved, but the difficulty of detecting and measuring the signal increases
Solution Approach 1:
The system implements periodic action by cycling through a predetermined set of frequencies in a systematic manner. The audio tone frequency changes at regular time intervals, creating a periodic pattern that is predictable enough for legitimate verification but complex enough to prevent simple replay attacks. This structured frequency modulation balances security requirements with detectability.
3Reliability
If the cryptographic device continuously monitors audio signals in real-time, then audio misappropriation prevention is improved, but the energy consumption increases
Solution Approach 1:
The system applies skipping by performing continuous monitoring only during critical time windows when audio signals are being transmitted or when frequency changes occur. Rather than maintaining constant high-level monitoring, the system rapidly checks audio levels at key moments and processes changes immediately, reducing overall energy consumption while maintaining effective prevention of misappropriation.
