Image Forming Apparatus Dual-Authentication Voice Biometrics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image forming apparatus authentication systems cannot prevent unauthorized access when an unauthorized user obtains and mimics an authorized user's mobile device, as they rely solely on device identification without robust biometric verification.
Innovation Solution
The implementation of a dual-authentication system that combines device identification with voice biometric authentication, where the image forming apparatus stores and verifies both user ID and voice information, enabling operations only for authenticated users and preventing 'spoofing' by third parties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mobile device authentication is used, then user identification is simplified, but security against spoofing is weakened
Solution Approach 1:
The patent combines mobile device identification with voice biometric authentication into a unified dual-factor authentication system. The control device receives both the mobile device ID and voiceprint information, and only authorizes operations when both factors match registered users, thereby maintaining ease of operation while significantly enhancing security against spoofing attacks
Solution Approach 2:
The authentication system transitions from relying solely on device identification parameters to incorporating biometric voiceprint parameters. This parameter expansion from single-factor to multi-factor authentication changes the security verification mechanism, making it resistant to mobile device spoofing while preserving user-friendly access
2Reliability
If dual authentication is implemented, then security against spoofing is improved, but system complexity increases
Solution Approach 1:
The control device serves as an intermediary that manages the dual authentication process. It receives mobile device IDs and voiceprint information, performs verification against registered user data, and controls operation authorization. This intermediary architecture consolidates the complexity within a dedicated component rather than distributing it across the entire system
Solution Approach 2:
The system creates and stores voiceprint copies (biometric templates) of authorized users during registration. During authentication, the live voiceprint is compared against these stored copies rather than requiring complex real-time analysis, thereby simplifying the verification process while maintaining high security standards

AI summary
An image forming apparatus includes a memory that stores identification information of authorized users in association with biometric information thereof, a reading device configured to read identification information from a medium, an input device through which biometric information is input, and a processor configured to, upon receipt of one of identification and biometric information, perform a first authentication by determining whether said one of identification and biometric information is stored, when said one of identification and biometric information is stored, upon receipt of the other of identification and biometric information, perform a second authentication by determining whether the other of identification and biometric information is stored in association with said one of identification and biometric information, and when the other of identification and biometric information is stored, enable a first operation that can be performed for the corresponding authorized user.
