Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Messages and communications over the internet are vulnerable to interception, especially when sensitive information is involved, necessitating improved methods for secure transmission and verification.
Innovation Solution
A computing platform uses tonal bits, trained with historical communication parameters, to embed secure communication validation information in audio signals, employing frequency and time domain multiplexing, and encrypts the communication, with intermediary waypoints for modification and verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication validation information is embedded using tonal bits in audio signals, then security and integrity of communications is enhanced, but device complexity increases
Solution Approach 1:
The patent introduces intermediary waypoints that act as mediators in the communication path. These waypoints embed validation information using tonal bits and perform verification without requiring the end devices to implement complex security protocols directly, thus enhancing security while managing device complexity
Solution Approach 2:
The patent replaces traditional mechanical or digital security verification mechanisms with acoustic-based tonal bit embedding. By using audio frequency modulation to encode validation information, the system achieves enhanced security through a fundamentally different physical layer approach
2Measurement precision
If validation information is embedded in audio signals, then detection of interference is improved, but loss of information increases
Solution Approach 1:
The patent changes the parameters of the audio signal by embedding validation information in specific frequency ranges (tonal bits). This allows the system to detect interference by monitoring changes in these parameters while maintaining the integrity of the original communication content
Solution Approach 2:
The validation information is embedded using periodic tonal patterns at specific frequencies. This periodic structure makes the validation information robust against random noise and interference, allowing reliable detection without losing the underlying communication information
3Reliability
If encryption is applied to secure event communication, then security is enhanced, but loss of time increases
Solution Approach 1:
The patent performs preliminary embedding of validation information using tonal bits before the main communication occurs. This pre-established validation mechanism allows for faster verification later, reducing the time penalty typically associated with encryption and decryption operations

AI summary
A computing platform may receive an event processing request. The computing platform may identify, by inputting first communication parameters of the event processing request into a secure communication model, communication validation information for the event processing request. The computing platform may embed, using one or more tonal bits of an audio communication corresponding to the event processing request, the first communication validation information, wherein embedding the first communication validation information generates a secure event communication. The computing platform may send the secure event communication to a recipient user device, where the recipient user device may be configured to verify the secure event communication based on the first communication validation information.
