Window Management for Secure Browsing on Shared Touch Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for setting security levels for content displayed on large-sized touch panels used by multiple users are costly and unrealistic, especially when application programs and publication levels are diverse and detailed, as they require individual settings for user groups, which is not feasible.
Innovation Solution
An information processing apparatus and method that includes a display section, a window management section, and a communication section to manage the display of windows on a large-sized touch panel, where the window management section determines the acceptability of browsing based on visual field ranges and browsability lists, allowing only registered users to browse certain windows by switching their display state to non-display, semi-transparent, or compressed, and transmitting non-browsable window lists to portable terminals for instruction-based changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual security levels are set for each content and user group, then security and privacy protection is improved, but device complexity and setting cost increase significantly
Solution Approach 1:
The system automatically determines browsing acceptability by detecting user positions and visual fields, eliminating the need for manual security level settings. The browsability determination is performed autonomously based on spatial relationships between users and displayed content.
Solution Approach 2:
The system changes the parameter of display visibility based on user position detection. When a user is detected to be in a position where they can view sensitive content, the system modifies the display parameters to restrict accessibility, transforming static security settings into dynamic position-based control.
2Reliability
If pre-setting acceptability for multiple users is implemented, then browsing security is improved, but ease of operation deteriorates due to complex configuration requirements
Solution Approach 1:
The system performs self-configuration by automatically detecting user positions and determining browsing acceptability without requiring operator intervention. The browsability list is dynamically generated based on real-time position detection, eliminating manual configuration needs.
Solution Approach 2:
The system performs preliminary detection of user positions and visual fields before determining browsing acceptability. By pre-establishing the relationship between user positions and content visibility, the system prepares security decisions in advance without requiring explicit user input or configuration.
3Reliability
If dynamic browsing control based on position detection is implemented, then browsing security is improved, but device complexity increases due to imaging and detection sections
Solution Approach 1:
The imaging section serves multiple functions: capturing user positions, determining visual fields, and triggering browsing control decisions. This multi-functional approach reduces the need for separate dedicated components for each function, thereby limiting complexity increase.

AI summary
There is provided an information processing apparatus including a display section which displays a window for each content including an application program used for each user, and a window management section which manages a display of the window displayed on the display section, at the time when the window is displayed on the display section in a state capable of being browsed by a user not registered in a permitter list to which a user permitted to browse the window is registered, in a state not able to be browsed or difficult to be browsed for a user not registered in the permitter list.
