Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing verification code technologies using randomly-generated numbers or symbols are easily cracked, resulting in low reliability for security verification.
Innovation Solution
A security verification method that uses a live view picture obtained through live view image capture based on image capture parameters and prestored street view tile information, which is difficult to crack, improving reliability by employing image matting processing and jigsaw verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If randomly-generated numbers or symbols are used as verification code information, then the verification code can be easily generated and displayed, but the security verification reliability is low and can be easily cracked
Solution Approach 1:
The patent transforms the verification code from simple numerical/symbolic data into complex image data with multiple parameters including capture time, device information, location data, and environmental factors. This parameter enrichment makes each verification code unique and difficult to replicate, directly addressing the reliability issue while maintaining systematic complexity management
Solution Approach 2:
The verification code combines multiple types of information (image data, metadata, device parameters, temporal information) into a composite verification structure. This composite approach creates a multi-layered security mechanism that is resistant to cracking while the system manages the complexity through structured integration of these diverse elements
2Reliability
If live view picture with multiple parameters is used for verification, then the security reliability is significantly enhanced, but the system complexity and processing requirements increase
Solution Approach 1:
The patent divides the verification system into distinct functional modules: image capture module, parameter extraction module, verification code generation module, and validation module. Each module handles specific tasks independently, which manages system complexity while enabling the use of complex live view pictures with multiple parameters for enhanced security
Solution Approach 2:
The patent introduces an intermediary processing layer that captures live view pictures and extracts relevant parameters (time, device info, location) before generating the final verification code. This intermediary structure manages the complexity of handling multiple parameters by systematically processing them through defined stages, making the overall system more manageable while maintaining high reliability

AI summary
A security verification method, apparatus, and system relate to the field of computer security technologies, and are used to improve reliability of the verification code technology. In the method, an image capture request carrying an image capture parameter is sent to a server end; a live view picture returned by the server end is received, where the live view picture is obtained by performing live view image capture according to the image capture parameter and prestored street view tile information; and a security verification operation is performed according to the live view picture.
