Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transmitting information using wireless hidden signals face challenges in security, as they either increase the likelihood of detection due to continuous signal generation or are easily recognizable as abnormal when using non-standard signals.
Innovation Solution
A module and method that generate a transmission data frame structure, encode it into a hidden encoded bit stream, and convert it into a wireless signal, using a hidden formatting unit, encoding unit, and modulation unit to minimize detection by distributing bit values and using only one frequency or normal beacon intervals, ensuring the signal is only detectable by intended parties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless hidden signals are continuously generated to transmit information, then information transmission reliability is improved, but the possibility of the signal being discovered increases
Solution Approach 1:
The patent applies periodic action by generating wireless hidden signals only during specific beacon intervals rather than continuously. The transmitting device embeds hidden information in selected beacon intervals based on predetermined conditions, creating periodic transmission patterns that maintain reliability while reducing continuous signal presence that could lead to detection
Solution Approach 2:
The patent applies local quality by making different beacon intervals have different functions - some intervals contain hidden information while others do not. This selective embedding approach means only specific local instances of beacon intervals carry the hidden signal, reducing overall detectability while maintaining transmission capability when needed
2Reliability
If non-communication wireless signals are used for hidden information transmission, then security is improved, but the signals are easily recognizable as abnormal
Solution Approach 1:
The patent applies universality by using beacon signals that serve multiple functions - both as standard communication beacons and as carriers for hidden information. This multi-functionality allows the same signal structure to perform normal beacon operations while simultaneously embedding hidden data, making the signal appear normal to conventional systems while still conveying secret information
Solution Approach 2:
The patent uses beacon signals as an intermediary carrier for hidden information. Rather than using dedicated hidden communication channels that would be easily identified, the beacon signals act as a mediator that naturally occurs in the wireless environment, allowing hidden data to be concealed within a signal that is already expected and accepted by wireless devices
3Reliability
If channel encoding is used for error verification, then transmission reliability is improved, but transmission speed decreases due to additional bits
Solution Approach 1:
The patent extracts the error verification function from traditional channel encoding and implements it through selective repetition of beacon intervals instead of adding redundant bits to every data transmission. This approach separates error handling from the main data stream, maintaining speed while providing reliability through periodic verification opportunities
