Proximity-Based Authentication Image Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional authentication systems require multiple user operations to display authentication images, leading to poor operability and potential leakage of authentication images after they are read.
Innovation Solution
An authentication system that includes a terminal apparatus with a communication unit, a determining unit to assess proximity to an information processing apparatus, and a display controller to automatically display an authentication screen containing an authentication image when within a specific communication range, ensuring secure and efficient image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal apparatus continuously displays the authentication image after it is read, then the authentication process is completed, but the authentication image may be leaked
Solution Approach 1:
The system determines the communication range in advance before displaying the authentication image. By pre-assessing whether the terminal apparatus is within the second communication range (distance ≤ threshold), the system ensures that the authentication image is only displayed when the information processing apparatus is nearby, preventing leakage scenarios where the image would be displayed without proper authentication context.
Solution Approach 2:
The system continuously monitors communication status and adjusts display behavior based on real-time feedback. The display controller checks whether the terminal apparatus remains within the second communication range and controls the display unit to stop showing the authentication image when the apparatus moves out of range or authentication is complete, dynamically responding to changing conditions to maintain security.
2Reliability
If multiple operation inputs are required to display the authentication image, then authentication control is maintained, but operability deteriorates
Solution Approach 1:
The terminal apparatus automatically determines its own communication range status and triggers the authentication image display without requiring user intervention. The first determining unit autonomously assesses whether the apparatus is within the second communication range, and the display controller automatically displays the authentication image when conditions are met, eliminating the need for multiple manual operation inputs while maintaining security through automatic range verification.

AI summary
An authentication system includes: an information processing apparatus configured to acquire, from a read result of an authentication image indicating authentication information, the authentication information; and a terminal apparatus configured to communicate with the information processing apparatus. The terminal apparatus includes: a communication unit configured to perform wireless communication with the information processing apparatus; a first determining unit configured to determine whether the terminal apparatus is positioned within a second communication range in which a distance from the information processing apparatus is a threshold or less, within a first communication range that enables wireless communication with the information processing apparatus; and a display controller configured to perform control to display an authentication screen containing the authentication image on a display unit when it is determined that the terminal apparatus is positioned within the second communication range.
