Real-Time Audio Confidentiality via Selective Stream Alteration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for securing audio and visual communications, such as natural language processing systems, are impractical due to high costs, extensive processing power requirements, and lengthy implementation times, making them unsuitable for providing real-time confidentiality in confidential communications.
Innovation Solution
Rapid confidentiality techniques (RCT) that allow for the alteration of specific portions of audio or video recordings in real-time by receiving indications to start and stop altering, using methods like masking, blurring, or removing sensitive information, without requiring expensive equipment or specialized processing, and can operate within existing communication networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If natural language processing systems are used to secure audio communications, then confidentiality protection is improved, but cost and processing power requirements increase significantly
Solution Approach 1:
The patent extracts only the essential function of confidentiality protection from complex NLP systems, implementing it through simple audio alteration techniques (masking, blurring, removing) that require minimal processing power while maintaining security effectiveness
Solution Approach 2:
The invention replaces expensive, complex NLP systems with inexpensive, simple audio alteration methods that can be implemented quickly and discarded or updated easily, eliminating the need for costly specialized processing infrastructure
2Reliability
If natural language processing systems are used to secure audio communications, then confidentiality protection is improved, but implementation time increases significantly
Solution Approach 1:
The patent extracts the core confidentiality function from complex NLP systems and implements it through straightforward audio processing techniques that can be deployed immediately without lengthy implementation cycles
Solution Approach 2:
The system performs preliminary actions by altering audio segments before storage or transmission, enabling quick implementation of security measures without requiring complex setup or training periods associated with NLP systems
3Reliability
If audio stream alteration is applied to protect confidential information, then privacy protection is improved, but the original audio content is modified
Solution Approach 1:
The patent segments the audio stream into distinct portions, applying alteration only to specific segments containing confidential information while leaving other segments unchanged, thus balancing privacy protection with audio content integrity
Solution Approach 2:
The invention applies local quality by altering only the specific portions of the audio stream that contain confidential information, rather than modifying the entire audio content, thereby maintaining the original quality and integrity of non-sensitive segments
Data Source
AI summary
A recording of an audio stream is initiated. The audio stream is a part of a communication between two or more participants. A first indication related to the audio stream is received. The first indication is that the audio stream should start being altered. A second indication related to the audio stream is received. The second indication is that the audio stream should stop being altered. A portion of the recorded audio stream between the first indication and the second indication is altered.
