Steganographic Media Embedding for Secure Video Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video conferencing technologies face significant security risks due to loopholes that allow hackers to steal user media information, compromising privacy during transmission.
Innovation Solution
A network information transmission method and system that processes and integrates media information from a first terminal device into a second media stream, hiding the sensitive information within the stream using steganography techniques, allowing secure transmission and decryption at the receiving end to prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If media information is transmitted directly through network streaming, then transmission efficiency is improved, but information security deteriorates due to vulnerabilities that allow hackers to steal user media information
Solution Approach 1:
The patent embeds the first media information within the second media information stream, creating a nested structure where the sensitive data is concealed inside the carrier stream. This allows the media information to be transmitted efficiently while maintaining security, as the embedded data remains hidden within the larger stream structure and can only be extracted by authorized parties with the proper decryption keys.
2Reliability
If media information is processed and integrated into another stream, then information security is improved through hiding, but device complexity increases due to additional processing steps
Solution Approach 1:
The patent introduces a second media information stream as an intermediary carrier that contains the first media information. This intermediary approach allows for secure transmission without requiring complex encryption of the original data, as the embedding process utilizes the structure of the carrier stream itself to protect the sensitive information.
3Reliability
If steganography techniques are used to hide media information, then information security is improved, but measurement precision of the hidden information deteriorates due to potential detection difficulties
Solution Approach 1:
The patent applies local quality modification to the media stream during the embedding process, making subtle changes to specific local characteristics of the carrier stream that accommodate the hidden data without creating obvious detection patterns. This allows the hidden information to remain securely embedded while maintaining the overall quality and natural appearance of the media stream.

AI summary
A network information transmission method, comprising the following steps: receiving a first media information by a first terminal device; processing the first media information to obtain a processed first media information; integrating the processed first media information into a second media information to generate an integrated second media information; outputting the integrated second media information to a second terminal device through the network; decompressing the integrated second media information through the second terminal device; capturing the integrated second media information through the second terminal device; obtaining the first media information based on the integrated second media information; and playing the first media information by the second terminal device.
