Secure Mobile Device Control Module for Unauthorized Communication Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current secure communication technologies lack mechanisms to supervise unauthorized calls between users from different institutions or with different duties within the same institution, and fail to remotely control the deletion of confidential information from lost or maliciously accessed mobile devices, leading to potential misuse of messages sent unintentionally or by malicious individuals.
Innovation Solution
A system that includes a secure mobile device with a control module to manage incoming and outgoing calls and messages based on digital signature verification, a database for subscriber information, and a management center to send urgent deletion messages and update lists, ensuring only authorized communications occur, and transferring the device's last location information after information deletion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If remote deletion of information is enabled without verification, then device security is improved, but risk of unauthorized deletion by malicious users increases
Solution Approach 1:
A management center acts as an intermediary between users and the remote deletion process. The management center receives deletion requests, verifies user authorization status, and only then executes the deletion command on the target device. This intermediary mechanism ensures that only authenticated users can delete information while preventing malicious unauthorized deletion attempts.
Solution Approach 2:
The system implements a feedback mechanism where the management center communicates with both the user initiating deletion and the target device. The management center provides feedback on whether the deletion request is authorized, and the device provides feedback on the deletion status. This closed-loop feedback ensures proper authorization verification before execution.
2Adaptability or versatility
If all secure mobile devices can communicate freely, then communication flexibility is improved, but inability to supervise unauthorized calls between different institutions increases
Solution Approach 1:
The communication network is segmented into different institutions or organizational units, each with its own identification. The management center maintains separation between these segments while allowing controlled interaction. This segmentation enables supervision of calls between different institutions without compromising the flexibility of communication within each segment.
Solution Approach 2:
The management center serves multiple functions: it manages device registrations, handles information deletion requests, supervises communication patterns, and enforces institutional boundaries. This universal management system provides comprehensive control without requiring separate mechanisms for each function, reducing overall system complexity.
3Reliability
If banned list distribution continues after device loss, then communication control is maintained, but unauthorized operations using banned subscriber numbers persist
Solution Approach 1:
When a device is reported lost or stolen, the management center immediately executes preliminary actions: it bans the subscriber number, deletes any stored confidential information, and prevents further communication using that device. This preliminary banning occurs before any potential unauthorized operations can take place, blocking malicious use at the source.
Solution Approach 2:
The system extracts and removes confidential information from the lost device remotely through the management center. By taking out the sensitive data before the device falls into malicious hands, the system prevents information exposure even if the physical device is compromised. The banned list mechanism then extracts and blocks the device's communication capability.
