MFD Authentication via Heartbeat Signal and Network Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for securing multi-functional devices (MFDs) connected to secure networks require expensive and cumbersome physical repositioning in restricted areas, which is not always feasible or cost-effective.
Innovation Solution
A system and method for authenticating users over a secure network that allows MFDs to remain in unsecured areas by using a user input/output assembly to receive credentials, which are verified by a secure server, and a heartbeat signal mechanism to control access, ensuring only authorized users can access the device's functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If MFDs are physically repositioned into restricted areas to ensure security, then security is improved, but renovation costs and implementation complexity increase substantially
Solution Approach 1:
The patent replaces the mechanical/physical security system (restricting MFDs to secured rooms or vaults) with an electronic authentication system. The access control system uses electronic credentials, password verification, and control signals to secure MFDs, eliminating the need for physical repositioning and associated renovation work while maintaining security.
2Reliability
If MFDs are placed in secured areas to limit access, then unauthorized access is prevented, but access convenience for authorized users deteriorates
Solution Approach 1:
The patent introduces an intermediary access control system that mediates between authorized users and MFDs. This system includes credential verification, password authentication, and control signal generation that automatically grants access to authorized users without requiring them to physically access secured areas, thus maintaining security while improving convenience.
3Reliability
If physical security measures are implemented to protect MFDs, then security is improved, but cost increases substantially
Solution Approach 1:
The patent substitutes expensive physical security infrastructure (secured rooms, vaults, access control hardware) with a software-based authentication system. The access control system uses electronic credentials, password verification, and network communication to provide security at a fraction of the cost of physical renovations.
4Ease of operation
If MFDs remain in unsecured areas to maintain operational flexibility, then ease of operation is improved, but security deteriorates
Solution Approach 1:
The patent introduces an access control intermediary that enables MFDs to remain in unsecured areas while maintaining security. The system monitors authentication status through heartbeat signals and control signals, allowing operational flexibility while preventing unauthorized access through electronic verification mechanisms.
Data Source
AI summary
A multi-functional device is attached to a secure network and includes a control circuit. The control circuit receives indications as to whether a user is authenticated to use the multi-functional device and in response, generates and sends a control signal to the multi-functional device. As long as the multi-functional device continues to receive the control signal, the multi-functional device remains in an operational mode to allow the authenticated user to access the multi-functional device functions. If the multi-functional device ceases to receive the control signal, the multi-functional device deactivates itself.
