Terminal Verification Using Machine Parameter Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The authenticity of terminals, such as mobile phones, is difficult to verify due to the rise of imitation devices, where modified internal chip information can lead to unreliable configuration parameters, reducing the accuracy of detection methods.
Innovation Solution
A terminal verification method that reads machine verification parameters, determines if they satisfy specific conditions by matching with fake machine configuration parameters from a library, and displays the result on a user interface, thereby identifying fake terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If configuration parameters are obtained and compared with official parameters, then terminal authenticity can be verified, but misdetection occurs when internal chip information is modified
Solution Approach 1:
The patent creates a copy of the original terminal by extracting configuration parameters from the official terminal and storing them in a database. This copy is then used for verification by comparing parameters from the tested terminal against the stored copy, enabling authenticity verification without directly accessing the official terminal during detection.
Solution Approach 2:
The patent performs preliminary extraction and storage of configuration parameters from the official terminal before the actual verification process. The database is pre-populated with authentic parameters, allowing rapid comparison and detection during the verification phase without needing to access the original terminal.
2Adaptability or versatility
If internal chip information is modified to improve terminal functionality, then terminal performance can be enhanced, but parameter reliability decreases leading to detection failures
Solution Approach 1:
By creating a database copy of the original terminal's configuration parameters, the system can detect modified parameters even when the terminal has been enhanced or modified. The copy serves as a reference standard that reveals any deviations from the original configuration.
Solution Approach 2:
The patent implements a feedback mechanism where the detected parameters are compared against the stored copy, and any discrepancies are identified and reported. This feedback loop enables the system to detect modifications and provide verification results to the user.
3Measurement precision
If multiple configuration parameters are compared, then detection accuracy improves, but detection complexity increases
Solution Approach 1:
The patent segments the verification process into distinct steps: extracting parameters from the tested terminal, retrieving corresponding parameters from the database, comparing each parameter pair, and generating verification results. This segmentation makes the complex multi-parameter comparison process more manageable and systematic.
Solution Approach 2:
By storing a complete copy of the original terminal's configuration parameters in the database, the system simplifies the comparison process. Instead of manually managing multiple reference parameters, the system automatically retrieves the corresponding parameter from the stored copy for each detected parameter.
