Human Body Communication Multi-User Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming apparatuses using individual person authentication methods, such as fingerprint or card authentication, can only manage one user at a time, leading to cumbersome user switching and security issues, as operations by other users are incorrectly attributed to the authenticated user, and the configuration becomes complex and costly with multiple operation members.
Innovation Solution
An information equipment apparatus that uses human body communication to identify operators by correlating control operations with the operator through a communication section and control section, allowing for simultaneous management of multiple users without special operations, and simplifying the interface by using a communication path through the operator's body to authenticate and control operations based on identification data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional individual person authentication methods (fingerprint, card) are used, then security is improved, but the apparatus can only manage one user at a time and user switching becomes cumbersome
Solution Approach 1:
The system automatically detects multiple operators through human body communication and performs identification without requiring manual authentication operations from each user. The apparatus self-manages multiple user sessions by detecting presence and exchanging identification data automatically, eliminating the need for users to perform switching operations.
Solution Approach 2:
The patent replaces manual authentication mechanisms (fingerprint scanners, card readers) with human body communication technology. Instead of mechanical or electronic authentication devices, the system uses the human body itself as a communication path to exchange identification data, enabling automatic multi-user detection and management.
2Reliability
If conventional authentication methods are used, then security is improved, but operations by other users are incorrectly attributed to the authenticated user
Solution Approach 1:
Each operator automatically provides their identification data through human body communication when they approach or interact with the apparatus. The system autonomously detects multiple operators and associates operations with the correct identified operator without requiring manual authentication, ensuring accurate operator attribution.
Solution Approach 2:
The system continuously monitors for the presence of multiple operators through human body communication and dynamically adjusts operation attribution based on real-time identification data exchange. When an operation is detected, the system feedbacks to verify which identified operator should be credited with the operation, preventing misattribution.
3Adaptability or versatility
If multiple operation members are provided for different users, then multi-user management is improved, but the configuration becomes complex and costly
Solution Approach 1:
The patent uses a single operation section that can serve multiple users simultaneously through human body communication. Instead of providing separate operation members for each user, the apparatus universally accepts operations from any detected operator and automatically identifies them through communication with their terminal apparatuses, eliminating the need for multiple dedicated interfaces.
Solution Approach 2:
The system merges the functionality of multiple user-specific operation sections into a single operation section. By combining user detection, identification data exchange, and operation processing into one unified interface, the apparatus achieves multi-user management capability without the complexity and cost of multiple separate operation members.
