Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Handheld devices running Windows CE and other operating systems face data loss due to unsecured hard resets, which can be inadvertently or maliciously triggered, leading to catastrophic consequences for users and enterprises.

Innovation Solution

Implementing a customized hard reset service that enforces security compliance by prompting users for authentication credentials and backing up data to external locations before proceeding with the hard reset operation, ensuring that only authorized resets occur and vital data is secured.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a hard reset operation is performed on a handheld device, then the device can be restored to its original state, but all user application data is erased causing catastrophic data loss

Engineering Contradiction:

Improvedevice restoration capabilityVSAvoiduser application data

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The system performs data backup to a secure location before the hard reset operation erases user data. The backup service creates a backup of user application data to a secure location that is not affected by the hard reset, preserving data before the destructive action occurs.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

A backup service acts as an intermediary between the hard reset operation and user data. This service intercepts the hard reset command, performs the necessary data backup to a secure location, and then allows the reset to proceed, mediating between the restoration need and data preservation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If hard reset operation is made easily accessible for device restoration, then device recovery is simplified, but unauthorized or inadvertent resets can occur causing data loss

Engineering Contradiction:

Improvedevice recovery processVSAvoidunauthorized reset operations

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system implements a feedback mechanism where the backup service monitors for hard reset commands and responds by performing data backup before allowing the reset to proceed. This feedback loop ensures that every hard reset attempt triggers the protective backup action.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The backup service automatically performs data backup without requiring explicit user authorization beyond the initial hard reset command. The system serves itself by automatically protecting data when a hard reset is initiated, eliminating the need for separate authorization steps while maintaining security.

Inventive Principle:

Principle #25Self-service

AI summary

Mechanisms to secure data on a hard reset of a device are provided. A hard reset request is detected on a handheld device. Before the hard reset is permitted to process an additional security compliance check is made. Assuming, the additional security compliance check is successful and before the hard reset is processed, the data of the handheld device is backed up to a configurable location.
