Stolen Terminal State Verification via Server Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for indicating a stolen terminal do not provide sufficient identification, leading to the risk of users buying stolen devices and facilitating wrongful theft, as only a small group knows the terminal is stolen, and the theft cannot be effectively captured.
Innovation Solution
A method and device for processing a stolen terminal that involves receiving a state modification message, verifying its legality, and updating the terminal's state information on a server to indicate it as stolen, allowing buyers to query and prevent transactions, thereby increasing recovery chances and curbing theft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal is marked as stolen by calling the police, then the terminal can be identified as stolen by authorities, but the information cannot be widely disseminated to prevent transactions
Solution Approach 1:
The patent introduces a server as an intermediary between the terminal and potential buyers. The server stores and manages the stolen terminal information, acting as a central repository that can be queried by anyone. This intermediary system allows the theft information to be widely disseminated without requiring direct communication between the police and every potential buyer, thus resolving the contradiction between reliable identification and information dissemination.
Solution Approach 2:
The system implements a feedback mechanism where the server continuously updates and maintains the status of terminals in its database. When a terminal is reported stolen, this information is fed back to the server, which then makes it available for query by potential buyers. This feedback loop ensures that the most current theft information is available to prevent transactions, addressing both the reliability and dissemination requirements.
2Productivity
If no state modification mechanism is implemented, then terminal transactions can proceed freely, but stolen terminals cannot be identified and recovered
Solution Approach 1:
The system performs preliminary actions by pre-registering and storing terminal information in the server database before any transaction occurs. This includes capturing terminal identifiers and ownership details in advance. When a transaction is attempted, the buyer can query this pre-prepared information to verify the terminal's status, thus enabling both efficient transactions and reliable verification without interfering with the transaction process itself.
Solution Approach 2:
The server acts as an intermediary verification system that does not directly interfere with transactions but provides essential verification information. Buyers can query the server to check terminal status independently, allowing transactions to proceed freely if the terminal is legitimate while preventing transactions of stolen terminals. This intermediary approach maintains transaction efficiency while adding necessary reliability.
3Ease of operation
If state modification messages are accepted without verification, then the system is simple to operate, but malicious users can falsely mark terminals as stolen or remove theft markers
Solution Approach 1:
The system implements feedback mechanisms where the server verifies the authenticity of state modification messages before applying them. The server checks whether the terminal actually exists in its database and whether the modification request is legitimate. This feedback verification process ensures that only authentic state modifications are accepted, preventing malicious users from falsely marking terminals as stolen or removing theft markers, while maintaining operational simplicity for legitimate users.

AI summary
The invention provides multiple methods and devices for processing a stolen terminal. Therein, a method for processing a stolen terminal comprises: receiving a state modification message from a sending party, wherein the state modification message carries the current state of the terminal; and in a case where the state modification message is legal, forwarding the state modification message to a server, so that the server modifies the state information of the terminal stored in the server to be the current state according to the state modification message. By employing embodiments of the invention, the state information of a terminal can be modified, which solves the problem in the prior art that other identification cannot be provided to indicate whether the terminal is stolen or not, and can achieve the beneficial effects of increasing the probability of recovering a stolen terminal and effectively curbing the stealing acts.
