Voice Authentication System for Secure User Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional authentication systems require users to perform additional operations, such as inputting identification information or confirming specific processing requests, which can be burdensome for users.
Innovation Solution
An information processing system that connects with a user's communication device for voice communication, allowing users to simply utter voice information to identify themselves and confirm processing requests, using voice feature identification and speech recognition to determine permission for specific processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional authentication methods requiring additional user operations are used, then security against impersonation is improved, but user burden increases
Solution Approach 1:
The system uses the user's own voice as the authentication credential, eliminating the need for separate identification inputs. The user simply speaks their registered voice pattern, and the system automatically verifies it against stored voiceprints, making the authentication process self-contained and convenient while maintaining security
Solution Approach 2:
The patent replaces manual input operations (typing passwords, selecting options) with voice-based authentication. The acoustic field (voice) substitutes for mechanical input methods, allowing users to authenticate through natural speech rather than deliberate operational steps, thereby reducing user burden while maintaining reliability
2Reliability
If multiple authentication steps are required, then unauthorized access prevention is improved, but processing time increases
Solution Approach 1:
The patent combines identification and authentication into a single voice verification step. Instead of requiring separate steps for user identification and credential verification, the system merges these functions by using the voiceprint both to identify the user and to authenticate them simultaneously, reducing processing time while maintaining security
Solution Approach 2:
The system performs preliminary registration of voiceprints during setup, storing acoustic characteristics for future rapid comparison. This preliminary action enables quick authentication by simply comparing new voice inputs against pre-stored templates, eliminating the need for complex real-time analysis and reducing authentication processing time
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system reduces the burden on users by simplifying the authentication process through voice-based identification and confirmation, while effectively preventing unauthorized access and ensuring secure processing permissions.
Implementation Method 1
a voice communication device connected with the information processing system for the voice communication transmits voice information indicating a voice input in the voice communication device
Implementation Method 2
acquires requester voice feature information indicating a feature of a second voice of the presumed requester; determines whether a feature of a first voice indicated by received voice information and the feature of the second voice indicated by acquired requester voice feature information correspond
Data Source
AI summary
The information processing system acquires second user identification information associated with first user identification matching requester identification information included in processing information indicating details of a request for predetermined processing. The first user identification is used to identify a first user of the information processing system. The second user identification is used to identify the first user as a second user of a voice communication system enabling voice communication. Based on the acquired second user identification information, the information processing system causes the system to be connected with a user communication device of the second user identified with the second user identification information for the voice communication. The information processing system receives voice information from the user communication information. The information processing system performs speaker recognition and speech recognition on the voice information and determine whether to permit the predetermined processing.
