Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In shared workplaces, authorized users may inadvertently expose confidential data to onlookers when accessing it on computer monitors, and there is a risk of unauthorized access when the user leaves their computer unattended.
Innovation Solution
A system utilizing a private display device with a biometric sensor that ensures only authorized users can view confidential data by performing biometric checks, preventing exposure to unauthorized viewers and maintaining data security even in insecure environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a standard computer monitor is used to display confidential data, then data accessibility and ease of operation are improved, but data security and confidentiality are compromised due to inadvertent exposure to onlookers
Solution Approach 1:
The display system is segmented into multiple independent display devices (first display device and second display device) that can simultaneously display different data sets. The first display device displays confidential data with restricted viewing, while the second display device displays non-confidential data, thereby segregating sensitive information from public view and eliminating the harmful exposure effect.
Solution Approach 2:
Different display devices are assigned different display qualities and security characteristics based on local requirements. The first display device has restricted viewing capabilities suitable for confidential data, while the second display device has open viewing characteristics for non-confidential data, allowing each part of the system to have the appropriate quality for its specific function.
2Object-affected harmful factors
If biometric verification is implemented to ensure only authorized users can view confidential data, then data security is improved, but device complexity and operational difficulty increase
Solution Approach 1:
A processing module acts as an intermediary between the biometric sensor and the display device. The processing module receives biometric information from the sensor, processes it to determine user authorization, and then controls the display device accordingly. This intermediary simplifies the overall system architecture by centralizing the authentication logic and providing a clear interface between the sensor and display components.
Solution Approach 2:
The processing module serves multiple functions: it processes biometric data from different types of sensors (fingerprint, facial recognition, iris), determines user authorization status, controls multiple display devices, and manages data routing. This multi-functionality reduces the need for separate dedicated components for each function, thereby reducing overall system complexity despite the advanced security requirements.
3Object-affected harmful factors
If a private display device with biometric sensor is used, then data security and exclusivity are improved, but ease of operation and user convenience deteriorate due to additional authentication steps
Solution Approach 1:
Biometric authentication is performed in advance before the user accesses confidential data. The system captures and verifies biometric information prior to displaying sensitive information, ensuring that only authorized users can view confidential data. This preliminary authentication action prevents unauthorized access while allowing seamless operation once authorization is confirmed.
Solution Approach 2:
The biometric sensor automatically captures and processes user authentication data without requiring manual intervention. The system self-verifies the user's identity through the biometric characteristics and automatically grants or denies access to confidential data, eliminating the need for manual authentication procedures and maintaining user convenience despite enhanced security.
4Object-affected harmful factors
If multiple display devices are used to simultaneously display different data sets, then data security is improved through physical separation, but device complexity and cost increase
Solution Approach 1:
The display system is divided into multiple independent display devices, each capable of displaying different data sets simultaneously. The first display device is dedicated to confidential data while the second display device handles non-confidential data, creating physical separation that prevents inadvertent exposure. This segmentation allows confidential information to be viewed only on the restricted display device.
Solution Approach 2:
Multiple display devices are merged into a single integrated system controlled by one processing module. The processing module manages both display devices, routing appropriate data to each device based on security requirements. This merging approach allows the system to provide enhanced security through multiple displays while maintaining manageable complexity through centralized control.

AI summary
A system for securely displaying data in an insecure environment, the system comprising: a private display device for displaying the data and configured to enable a user to exclusively view the data thereon; a biometric sensor associated with the private display device and configured to receive biometric information from the user; and a processing module configured to: determine that the user is an authorised user based at least in part on a comparison of the biometric information received at the biometric sensor with biometric information of one or more authorised users; and permit the data to be displayed to the user on the private display device if the user is determined to be an authorised user.
