Coordinated Security System for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile electronic devices do not effectively prevent unauthorized use of communication functionality even after an invalid password is entered, as the SIM card remains active until network administrators deactivate it, allowing thieves to continue using communication services.
Innovation Solution
A system and method that coordinates multiple security measures by detecting an invalid access attempt, initiating a first security operation to prevent access to device applications, and triggering a second security operation to disable communication cards, such as SIM cards, ensuring comprehensive security features are activated even if an unauthorized user attempts to access the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only device application security is implemented without coordinating SIM card security, then device applications are protected but communication functionality remains vulnerable to unauthorized use
Solution Approach 1:
The patent merges device application security with SIM card security into a coordinated system. When invalid password attempts are detected on the device, the system automatically triggers SIM card deactivation through network registration failure, combining two separate security measures into a unified protection mechanism that addresses both device and communication security simultaneously.
Solution Approach 2:
The system performs preliminary security actions by pre-configuring the coordination mechanism between device security and SIM card security. Before an unauthorized access attempt occurs, the system establishes the security policy that links device password failures to SIM card deactivation, enabling automatic response without requiring real-time complex decision-making during the security event.
2Ease of operation
If SIM card remains active after invalid device password entry, then communication services can be restored easily, but unauthorized users can continue using communication functionality
Solution Approach 1:
The patent introduces network registration as an intermediary mechanism between device security and SIM card functionality. When device security is compromised, the system uses failed network registration attempts as a mediator to trigger SIM card deactivation. This intermediary approach allows automatic security response while maintaining the ability for authorized users to restore services through proper authentication channels.
Solution Approach 2:
The system implements feedback loops where network registration status provides information about SIM card security state. Failed registration attempts feed back into the security system, triggering further deactivation actions. This feedback mechanism enables automatic adaptation of security measures based on real-time system state without requiring external intervention for each security event.
3Reliability
If multiple security operations are coordinated, then comprehensive security coverage is achieved, but system response time and complexity increase
Solution Approach 1:
The system performs preliminary configuration of security coordination policies before security events occur. The mapping between device security events and SIM card responses is pre-established, allowing rapid automatic execution when security incidents happen, without requiring complex real-time decision-making that would consume time during critical security responses.
