Virtual Identity Module for Lost Terminal Data Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handsets, due to their increased functionality and portability, are prone to being lost or stolen, and existing methods struggle to effectively retrieve information from stolen devices without relying on physical identity modules.
Innovation Solution
Implementing a method that uses a virtual identity module to communicate with a server, allowing information from a lost terminal to be acquired without a physical identity module, enabling the transmission of current position, target data, or control instructions to protect sensitive information and increase the chances of recovering the stolen device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a physical identity module is used for communication, then communication can be established, but the terminal is vulnerable to information loss when lost or stolen
Solution Approach 1:
The patent creates a virtual identity module that replicates the functionality of a physical identity module. The virtual module stores the same communication credentials and can establish connections independently, serving as a digital copy that remains secure in the cloud rather than being physically vulnerable in the device.
Solution Approach 2:
The patent introduces a server as an intermediary between the terminal and the network. The server hosts the virtual identity module and manages communication authentication, acting as a mediator that enables secure communication without requiring the physical identity module to be present in the terminal.
2Reliability
If communication relies on physical identity module connection, then authentication is straightforward, but communication fails when the module is disconnected or unavailable
Solution Approach 1:
The terminal automatically detects the connection status of the physical identity module and autonomously switches to using the virtual identity module when the physical module is unavailable. This self-service mechanism ensures continuous communication availability without requiring manual user intervention or complex authentication procedures.
Solution Approach 2:
The virtual identity module is pre-configured and stored on the server before any loss or disconnection occurs. This preliminary preparation ensures that when the physical identity module becomes unavailable, the terminal can immediately use the pre-existing virtual module for authentication and communication without delay.
3Reliability
If data is stored in the terminal, then quick access is possible, but data is vulnerable to theft when the terminal is stolen
Solution Approach 1:
The patent moves data storage from the physical dimension (local terminal storage) to the virtual dimension (cloud-based server storage). The virtual identity module and associated data exist in a different dimensional space accessible through network communication, making them inaccessible to physical theft while maintaining quick access through digital connectivity.

AI summary
The present invention relates to a method and apparatus for acquiring information from a terminal, a computer program and a recording medium. The method comprises: detecting (S11) a state of a first terminal; and in response to the detected state indicating that the first terminal is lost, communicating (S12) with a server via a virtual identity module such that the server acquires information from the first terminal.
