Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile computing devices face issues with volatile memory leading to data loss, lack of authentication and encryption functions, and costly customization processes, which result in inefficient configuration and security management.
Innovation Solution
A system comprising a mobile computing device connected to an external storage medium with preconfigured security and user information, utilizing a card customization server and device security verification modules to manage authentication, encryption, and configuration, ensuring secure network access and automatic device wiping if conditions are not met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If volatile memory is used as persistent storage in mobile computing devices, then the device can operate with simpler storage architecture, but data loss occurs when device power is lost
Solution Approach 1:
The patent divides the storage system into two distinct segments: volatile memory for active operations and a separate non-volatile storage medium (such as a removable memory card) for persistent data storage. This segmentation allows the device to maintain simplicity in the main storage architecture while ensuring data persistence through the separate non-volatile component that retains data without power.
2Device complexity
If authentication and encryption functions are programmed at the application layer, then the operating system can remain simple, but these functions are expensive to implement and may be lost when power is lost
Solution Approach 1:
The patent implements authentication and encryption functions in advance by programming them directly into the operating system kernel rather than at the application layer. This preliminary action ensures that these critical security functions are permanently embedded in the system, cannot be lost when power is lost, and are always available before any application executes.
3Adaptability or versatility
If customization and configuration are performed through provisioning and re-provisioning, then the device can be adapted to different uses, but the process is time-consuming and requires frequent interventions
Solution Approach 1:
The patent enables the mobile computing device to perform self-configuration by automatically detecting the type of removable storage medium inserted and loading the appropriate configuration parameters and authentication data from the medium itself. This self-service approach eliminates the need for manual provisioning and re-provisioning, allowing the device to adapt to different uses automatically without user intervention or time-consuming configuration processes.
