Selective Display Security System for Multi-User Environments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information handling systems face challenges in protecting sensitive display screen content from unauthorized users, particularly in multi-user environments where sensitive information may be inadvertently exposed.
Innovation Solution
A selective display information security system that utilizes user presence detection sensors to identify multiple users within a field of view and applies security management actions based on predefined display security policies to protect sensitive content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user presence detection sensors are used to detect multiple users, then data security is improved, but device complexity increases
Solution Approach 1:
The user presence detection sensor serves multiple functions: detecting user presence, determining user count, and triggering security actions. This multi-functionality reduces the need for separate components for each function, thereby managing device complexity while improving data security through comprehensive monitoring.
Solution Approach 2:
A security manager component acts as an intermediary between the sensor and the display output. It receives sensor data, processes security policies, and determines appropriate actions. This intermediary layer simplifies the overall system architecture by centralizing security logic rather than distributing complex decision-making across multiple components.
2Reliability
If security management actions are applied to protect sensitive content, then data security is improved, but ease of operation deteriorates
Solution Approach 1:
The system automatically detects user presence and applies security actions without requiring manual user intervention. The security manager autonomously processes sensor data, evaluates policies, and executes appropriate actions such as obscuring sensitive content. This self-service approach improves data security while maintaining ease of operation by eliminating the need for users to manually configure or manage security settings.
Solution Approach 2:
The system changes display parameters (such as obscuring or blurring sensitive content) based on detected conditions. These parameter changes are applied dynamically and automatically, improving security without requiring users to manually adjust settings. The changes are transparent to the user and occur in response to environmental conditions rather than user actions.
3Reliability
If sensitive content is obscured or blurred when unauthorized users are detected, then data security is improved, but visibility and usability of display content deteriorates
Solution Approach 1:
The system applies different treatments to different portions of the display. Instead of obscuring the entire display, only sensitive content areas are obscured or blurred while non-sensitive content remains visible. This local quality approach maintains data security by protecting sensitive information while preserving visibility and usability of non-sensitive display content.
Solution Approach 2:
The display characteristics are dynamically adjusted based on real-time detection of user presence and sensitivity of displayed content. When unauthorized users are detected and sensitive content is identified, the system dynamically applies obscuring or blurring effects. When authorized users are present or no sensitive content is displayed, the display returns to its normal high-visibility state. This dynamic adjustment ensures data security without compromising visibility during normal operation.

AI summary
A system for selective protection of display screen content, wherein the system may be configured to receive input data that includes sensor data from a user presence detection sensor to detect presence of at least two users within a field of view of a display screen. The system also may determine whether an application includes sensitive content is on display. In addition, the system may determine a security management action as defined by a display security policy based on the presence of the at least two users within the field of view of the display screen and determine whether the application sensitive content is on display at the display screen. In response to a determination to apply the security management action, the system may perform the security management action to protect the sensitive content at the display screen.
