Wireless Signal Strength Based Access Control for Image Processors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing apparatuses require cumbersome authentication processes for remote access, which can be inconvenient, especially in scenarios where users need to access the apparatus from within a specific area without external authentication.
Innovation Solution
An image processing apparatus with a wireless communication unit and a controller that establishes a connection based on wireless signal reception intensity, allowing operations from devices within a predetermined area without authentication but preventing operations from outside devices, and displaying warnings for external devices not within the area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication process is required to ensure security, then security level is improved, but user convenience deteriorates due to troublesome login process
Solution Approach 1:
The system changes the parameter of authentication from binary (authenticated/not authenticated) to continuous (signal strength level). By evaluating wireless signal reception intensity as a parameter, the system determines access permissions based on the strength of the signal, eliminating the need for traditional authentication while maintaining security through physical proximity requirements.
2Ease of operation
If authentication process is eliminated for convenience, then user convenience is improved, but security level deteriorates as apparatus may be accessed from outside designated area
Solution Approach 1:
The wireless signal strength serves as an intermediary mechanism between the user and the apparatus. Instead of direct authentication or complete open access, the system uses signal intensity as a mediator to indirectly verify that the user is within the designated area, thus maintaining security while enabling convenient access.
3Speed
If wireless connection is established without authentication, then connection speed is improved, but risk of unauthorized access increases
Solution Approach 1:
The system performs self-service authentication by automatically evaluating the wireless signal strength and making access decisions based on predetermined thresholds. This eliminates the need for manual authentication processes while maintaining security, allowing the system to quickly determine whether to permit access without external intervention.

AI summary
An image processing apparatus including a wireless communication unit, an image processing unit, and a controller configured to establish a wireless connection to perform wireless signal communication between the wireless communication unit and an external device, acquire a reception intensity of a wireless signal received from the external device via the wireless communication unit, determine whether the reception intensity is more than a threshold value, when determining that the reception intensity is more than the threshold value, control the image processing unit to execute an image processing instruction received from the external device via the wireless communication unit, and when determining that the reception intensity is not more than the threshold value, transmit an instruction to display a warning on the external device, to the external device via the wireless communication unit, without controlling the image processing unit to execute the image processing instruction.
