Voice-Controlled Device Identifier Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Voice-controlled devices capture sensitive information beyond intended audio commands, such as background noise and other voices, which can be confidential and are not intended for disclosure to third-party applications, posing a security risk.
Innovation Solution
Associating unique identifiers with audio data and text corresponding to user commands, allowing third-party applications to reference this data without accessing the raw audio or text, thus maintaining confidentiality by only providing the identifiers to third-party applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If audio data and text are provided directly to third-party applications, then the applications can process and output relevant information, but confidential information including background noise and other voices is disclosed to third parties
Solution Approach 1:
The patent extracts only the necessary identifying characteristics from the audio data and associates them with unique identifiers. Third-party applications receive only these identifiers and associated text, not the raw audio data containing confidential information. This extraction approach enables information processing while removing harmful confidential content.
Solution Approach 2:
The patent introduces unique identifiers as an intermediary between the audio data and third-party applications. These identifiers serve as mediators that allow applications to reference and process information without direct access to the confidential audio content. The identifiers act as a buffer that maintains confidentiality while enabling functionality.
2Object-affected harmful factors
If unique identifiers are associated with audio data and only identifiers are provided to third-party applications, then confidential information is protected, but the applications cannot directly access the audio data for processing
Solution Approach 1:
The patent segments the audio data processing into distinct components: raw audio data retention, unique identifier generation, identifier-text association, and selective provision to third parties. This segmentation allows the system to maintain confidential audio data separately while providing only identifiers and associated text to applications, reducing data management complexity through structured organization.
Data Source
AI summary
A voice-controlled device may receive a voice command uttered by a user, where the voice command may request that the voice-controlled device perform an operation. The voice-controlled device and/or one or more remote computing resources may process an audio signal associated with the voice command to determine text corresponding to the voice command. The resulting user utterance may be associated with a unique identifier, which may be provided to a third party and/or third party application that is to provide information responsive to the user request. The information provided by the third party/third party application may be output to the user based at least partly on the unique identifier, without disclosing user data associated with the user.
