Voice Print Matching for Privacy-Safe Audio Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional voice communication systems face challenges in efficiently searching and authenticating user data due to large audio and audiovisual file sizes, which are time-consuming and risk compromising user identity and sensitive information, especially in compliance with data privacy laws.
Innovation Solution
Generating voice prints from audio features, which are used for secure data storage and efficient retrieval, allowing for decentralized storage formats like NoSQL databases, while masking personal information and enabling faster data processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If large audio and audiovisual files are stored conventionally in segments, then complete user communication data is preserved, but data storage requirements and processing time increase significantly
Solution Approach 1:
The patent extracts only the essential voice characteristics from complete audio files to create compact voice prints. Instead of storing entire audio recordings, the system extracts and stores only the unique voice identification features, which are then used to retrieve relevant communication data without requiring storage of the full audio files.
Solution Approach 2:
The patent creates simplified copies of voice data in the form of voice prints. These voice prints serve as compact representations that capture the essential identifying characteristics of user voice without requiring the original large audio files, enabling efficient storage and retrieval while maintaining the ability to identify and authenticate users.
2Ease of operation
If conventional voice communication systems store and search audio files, then user authentication and data retrieval are possible, but the process is time-consuming and inefficient
Solution Approach 1:
The patent performs preliminary processing of voice data by extracting voice prints and storing them in advance. When authentication or data retrieval is needed, the system can quickly compare the incoming voice print against pre-stored voice prints and associated metadata, eliminating the need to search through large audio files in real-time and significantly reducing processing time.
3Adaptability or versatility
If personal voice data is retained for service provision, then user service and authentication are enabled, but data privacy and security risks increase
Solution Approach 1:
The patent extracts only the necessary voice identification characteristics from personal voice data to create voice prints. These voice prints contain sufficient information for authentication and service provision but exclude unnecessary personal information, thereby reducing privacy and security risks while maintaining service functionality.
Solution Approach 2:
The patent uses voice prints as temporary, purpose-specific representations of voice data. Instead of retaining and repeatedly using sensitive personal voice recordings, the system creates disposable voice print representations that serve the authentication function without requiring long-term retention of sensitive personal data, thereby reducing security risks.
Data Source
AI summary
There are provided systems and methods for procedural pattern matching in audio and audiovisual files using voice prints. A user may utilize a computing device to interact with online service providers via voice communications. Based on audio and/or audiovisual data provided during the voice communications, voice prints may be generated, such as by determine audio signals from audio and/or audiovisual data, extracting audio features from such signals, and identifying voice and other audio dimensions in the audio and/or audiovisual data. The voice print may be generated based on an algorithmic calculation or other function that hides or obscures personal data for the corresponding user and/or masks the users voice and identity. The voice print may then be stored and used as a key for data associated with the user, which allows the data to be scrubbed or masked of the user's personal data to protect their privacy.
