Display Privacy via Fragmented Communication Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing visibility of computer screens in public places due to larger and brighter displays compromises user privacy, as sensitive information can be easily viewed by unintended individuals.
Innovation Solution
A security system that includes a sensitivity determining module to assess the sensitivity of communications, parsing them into fragments if the sensitivity value exceeds a threshold, and transmitting these fragments to ensure that sensitive information is not casually viewed by unintended recipients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If screen size and brightness are increased to improve readability, then display quality is improved, but privacy is compromised due to increased visibility to unintended viewers
Solution Approach 1:
The communication content is divided into multiple fragments that are displayed sequentially rather than all at once. This segmentation ensures that even if someone views the screen, they can only capture partial information at any given moment, thus resolving the privacy issue while maintaining readability through proper fragment design
Solution Approach 2:
The system displays fragments of the communication in a periodic sequence with controlled timing. Each fragment appears for a specified duration before transitioning to the next, creating a time-based viewing constraint that prevents unintended recipients from reading the entire message while allowing the intended recipient to read at a comfortable pace
2Ease of operation
If communication is displayed in full form for ease of reading, then readability is improved, but sensitivity protection is reduced
Solution Approach 1:
Sensitive communications are automatically segmented into multiple fragments based on their sensitivity level. The segmentation divides the complete message into discrete units that are displayed sequentially, maintaining readability for the intended recipient while preventing comprehensive viewing by unintended parties
Solution Approach 2:
The system applies different display qualities to different parts of the communication based on sensitivity analysis. Sensitive portions are fragmented and displayed with timing controls, while non-sensitive portions may be displayed in full form, creating localized protection where it is most needed while preserving overall readability
3Object-affected harmful factors
If communication is parsed into fragments for security, then privacy protection is improved, but device complexity increases
Solution Approach 1:
The system changes the parameter of message presentation from static full-display to dynamic fragmentated display with controlled timing. This parameter change enables privacy protection through fragmentation while the complexity is managed through automated algorithms that determine fragment boundaries and display timing based on message sensitivity and length
4Reliability
If sensitivity analysis is performed on communications, then privacy protection is improved, but processing time increases
Solution Approach 1:
The system performs sensitivity analysis and fragment preparation in advance before the communication needs to be displayed. By pre-processing the message to identify sensitive portions and create appropriate fragments, the system reduces real-time processing requirements while maintaining comprehensive sensitivity protection
Data Source
AI summary
A security method that includes assigning a sensitivity value for a communication with a sensitivity determining module including at least one hardware processor. Following assignment of the sensitivity value to the communication, the communication is formatted for display. When sensitivity value exceeds a security threshold, the communication is parsed into a sequence of fragments. The communication is transmitted as the sequence of fragments when said sensitivity value exceeds the security threshold.
