Mobile Device Security Module for Automatic Data Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communications devices pose a security risk due to the potential loss or theft, as sensitive information can be compromised if the user is unable to timely report the device missing, especially when they rely on it for communication.
Innovation Solution
A mobile communications device equipped with a security module that monitors for trigger conditions, such as disconnection from the network, and prompts the user for a bypass action; if this action is not taken within a predetermined time, the device automatically takes security measures, including data protection by erasure or encryption, to prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user contacts the network operator to send a kill packet to wipe data, then data security is improved, but the response time is delayed because the user must realize the device is missing and be able to communicate with the network
Solution Approach 1:
The security module is pre-configured with instructions to automatically wipe data when specific trigger conditions are detected (such as multiple failed authentication attempts or detection of theft), eliminating the need for user intervention and ensuring immediate response even when the user cannot contact the network operator
Solution Approach 2:
The mobile device performs the security action itself through an autonomous security module that monitors for trigger conditions and executes data protection measures without requiring external assistance from the network operator or user action
2Ease of operation
If the device requires user action to prevent data erasure, then user control is improved, but automatic protection is reduced when the user is unable to respond
Solution Approach 1:
The security system dynamically adjusts its behavior based on the situation: it allows user bypass action when the user is able to respond, but automatically executes data protection when trigger conditions indicate theft or loss and no user action is received within a predetermined time period

AI summary
A mobile communications device for communicating with a wireless network, including an electronic storage having data stored thereon, a processor connected to the storage for accessing the data, a communications sub-system connected to the processor for exchanging signals with the wireless network and with the processor, a user input interface connected to send user input signals to the processor in response to user action, and a security module associated with the processor for detecting a trigger condition and automatically taking a security action if a bypass user action is not detected after detection of the trigger condition.
