Locked Screen Device ID Display for Anti-Theft Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current anti-theft measures, such as the 'Kill Switch', render it difficult for law enforcement to identify the status of a stolen mobile device, as they become inaccessible and block ordinary methods of obtaining device identifiers.
Innovation Solution
A method and apparatus for displaying device identifications, such as IMEI, IMSI, MAC ID, MSISDN, or MIN, on the locked screen of a mobile device via a paging message, allowing law enforcement to easily identify the device's status during theft investigations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the Kill Switch anti-theft measure is activated, then device security is improved, but the ability to identify the device status by law enforcement deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-configuring the mobile device with a locked screen that displays device identification information (IMEI, IMSI, MAC address, etc.) before any theft occurs. When law enforcement needs to identify a stolen device, they can directly access this pre-prepared identification display without needing to bypass security measures or access network databases, thus resolving the contradiction between security and identifiability.
2Reliability
If the device is locked to prevent unauthorized access, then security is improved, but the ease of obtaining device identifiers by authorized personnel deteriorates
Solution Approach 1:
The patent introduces an intermediary element - the locked screen itself - that serves as a bridge between security requirements and law enforcement needs. The locked screen acts as a mediator by displaying device identification information in a visible manner while maintaining the locked state that prevents unauthorized access to the device's internal systems. This resolves the contradiction by providing authorized personnel with easy access to identifiers without compromising security.
3Reliability
If ordinary methods of obtaining device identifiers are blocked, then unauthorized access is prevented, but law enforcement investigation efficiency deteriorates
