Solution Overview

Problem

The transmission of non-voice data files over VoIP channels poses security risks due to the lack of effective control mechanisms, which can compromise important data information.

Innovation Solution

A data attribute detection method and system that recognizes media streams over voice channels, determining whether they contain voice or non-voice data, and applies control modes such as disturbance control by adding noise to prevent unauthorized transmission of non-voice data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If non-voice data files are transmitted over VoIP channels for convenience, then transmission ease is improved, but data security deteriorates due to lack of control mechanisms

Engineering Contradiction:
Improvetransmission convenienceVSAvoiddata security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary voice recognition on media streams before allowing transmission. By pre-identifying whether the media stream contains voice or non-voice data, the system can proactively apply control policies to prevent unauthorized non-voice data transmission, thus maintaining security while allowing legitimate voice communications to proceed conveniently

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements a feedback mechanism where the voice switch receives recognition results from the recognition server and automatically applies control policies. The system monitors transmitted media streams, identifies non-voice data, and responds by applying disturbance control or blocking the transmission, creating a closed-loop control system that maintains security without manual intervention

Inventive Principle:
Principle #23Feedback

2Measurement precision

If voice recognition is performed on all media streams to ensure security, then detection accuracy is improved, but system complexity increases

Engineering Contradiction:
Improvedata attribute detection accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments the security control function into separate modular components: a recognition server that performs voice recognition, a voice switch that receives recognition results, and a policy control module that applies control measures. This segmentation allows each component to perform its specific function independently, improving detection accuracy while managing system complexity through modular architecture

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a recognition server as an intermediary component between the media stream source and the voice switch. This intermediary performs the complex voice recognition task, allowing the voice switch to focus on policy enforcement. The intermediary handles the computational complexity of voice recognition, enabling accurate detection without overcomplicating the core switching system

Inventive Principle:
Principle #24Intermediary (Mediator)
