Facial Recognition Output Privacy System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In uncontrolled environments, such as public spaces, it is challenging to restrict access to confidential information displayed on computer screens, as the user cannot control who views the screen.
Innovation Solution
A computer system equipped with a camera that uses facial recognition to determine access permissions for individuals in proximity to the screen, modifying the display accordingly to restrict access to unauthorized viewers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the computer is used in an uncontrolled environment (public space), then work flexibility is improved, but access control to confidential information deteriorates
Solution Approach 1:
The patent introduces an intermediary system consisting of a camera, image analysis system, and output control system that mediates between the uncontrolled environment and the confidential information. The camera captures images of people near the computer, the image analysis system identifies them and determines their permission levels, and the output control system adjusts the display accordingly. This intermediary mechanism enables both flexible computer usage in public spaces and reliable access control through automated permission verification.
2Reliability
If the user controls who can view the screen in a defined environment, then access control to information is improved, but ease of operation deteriorates
Solution Approach 1:
The system implements self-service access control where the computer automatically performs identification and permission verification without requiring manual intervention from the user. The camera continuously monitors and captures images of people near the computer, the image analysis system automatically identifies them and checks their permission levels against the information being displayed, and the output control system automatically adjusts the display based on the results. This eliminates the need for users to manually control who can view the screen while maintaining secure access control.
3Reliability
If the computer restricts locations for use, then access control to information is improved, but work flexibility deteriorates
Solution Approach 1:
The patent implements dynamic access control that adapts to different people and situations in real-time. Instead of restricting the computer to fixed locations, the system dynamically adjusts the display based on the identity and permission level of each person detected near the computer. The output control system continuously monitors changes in the environment and modifies the display accordingly, allowing the computer to be used flexibly in various locations while maintaining appropriate access control through automated permission verification.
Data Source
AI summary
A system for controlling the privacy of data output by a computing system, particularly the privacy of data displayed on a display screen of a computer. Facial recognition is utilised to identify people in proximity to the output of the computer system and to control the output of the computer system dependent upon the identities of those people.
