Sensitive Information Filter for Display Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for maintaining display privacy of sensitive information on information handling devices, such as smartphones and laptops, are either ineffective in preventing unauthorized viewing or burdensome for authorized users, as physical privacy filters and redaction techniques fail to ensure secure visualization of sensitive information in public locations.
Innovation Solution
A method that determines if content displayed on a device contains sensitive information and filters it, transmitting the sensitive information to a secondary device for private visualization, such as an augmented reality headset or wireless headphones, while allowing non-sensitive content to be displayed on the primary device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical privacy filters or redaction techniques are used to protect sensitive information on display, then unauthorized viewing is prevented, but the user experience is degraded and secure visualization is not ensured
Solution Approach 1:
The system segments information into sensitive and non-sensitive portions, displaying non-sensitive information on the primary display while transmitting sensitive information to a secondary device. This segmentation allows the user to access all information without degradation of user experience while ensuring sensitive information is protected through separate transmission channels.
Solution Approach 2:
A secondary device acts as an intermediary for displaying sensitive information. The system transmits sensitive information to this intermediary device (such as augmented reality headset or wireless headphones) which then presents the information privately to the user, thereby maintaining both privacy protection effectiveness and user experience.
2Ease of operation
If sensitive information is displayed on the primary device, then the user can easily access it, but unauthorized individuals can also view it in public locations
Solution Approach 1:
The system extracts sensitive information from the content displayed on the primary device and transmits it separately to a secondary device. This extraction ensures that sensitive information is removed from the public display, preventing unauthorized viewing while maintaining user accessibility through the secondary device.
Solution Approach 2:
The system moves sensitive information from the visual display dimension (primary device screen) to another dimension (secondary device such as audio output or augmented reality). This dimensional change allows users to access information through a different sensory modality or device type, preventing unauthorized visual access while maintaining accessibility.
3Reliability
If all information is transmitted to a secondary device, then privacy is maximized, but the complexity of the system increases
Solution Approach 1:
The system applies partial action by transmitting only sensitive information to the secondary device while leaving non-sensitive information on the primary display. This selective transmission approach maximizes privacy protection for sensitive information while minimizing system complexity by avoiding the need to transmit all information.
