Solution Overview
Problem
Computing devices face challenges in securing proprietary information and ensuring authorized access, particularly in mobile devices that can be lost or stolen, while also needing to control communication and customize user interfaces for different user levels.
Innovation Solution
A secure computing device system with a processor, memory, and input/display components that provides a customizable user interface for granting and restricting access based on verified user identification, allowing for secure storage and communication, and customizable access levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a computing device stores valuable proprietary information and software, then competitive advantage and value are provided, but the risk of unauthorized access and loss increases
Solution Approach 1:
The user interface is segmented into multiple display modes (locked mode, unlocked mode, secure mode) that are presented based on user authorization levels. This segmentation allows the system to protect proprietary information by displaying different interface states to different users, thereby preventing unauthorized access while maintaining information security.
Solution Approach 2:
A processor acts as an intermediary between the user input and the displayed information. The processor receives user input, determines authorization status, and selectively displays appropriate interface modes. This intermediary mechanism controls access to proprietary information by filtering what information is presented to unauthorized versus authorized users.
2Reliability
If access controls are implemented to secure proprietary information, then security is improved, but user interface complexity increases
Solution Approach 1:
The user interface dynamically transitions between different display modes (locked, unlocked, secure) based on real-time user authorization status. This dynamic adaptation allows the system to maintain security while presenting a simplified interface to authorized users, as the interface complexity only increases when needed for authentication purposes.
Solution Approach 2:
The same user interface hardware and software infrastructure serves multiple functions: it displays both simple unlocked mode for authorized users and complex locked mode with security prompts for unauthorized users. This multi-functionality allows the system to maintain security without requiring separate interface systems, thereby limiting the increase in overall complexity.
3Adaptability or versatility
If multiple access levels are implemented for different users, then customized security control is improved, but system complexity increases
Solution Approach 1:
Different authorization levels and interface modes are applied locally to specific users based on their individual authorization status. The system evaluates each user's authorization level and presents the appropriate display mode (locked, unlocked, or secure) tailored to that user. This localized approach allows customized security control without requiring complex global access control mechanisms.
Data Source
AI summary
An apparatus and system for providing a secure user interface restricting the access of users to selected functions, files, and communications by implementing a customizable secure graphical user interface. The degree to which the user's access is restricted may depended on levels of authorization granted to the user. The secure user interface may be implemented on a device and employed to aid a user in executing diagnostic, service, maintenance, and data gathering tasks. The secure computing device may be connectable to other computing devices of like of different kind. The secure computing device may provide security against non-authorized users by requiring user identification and disabling the device when proper identification is not given or the device is deemed missing.
