Graphometric Signature Recognition via Fragmented Biometric Encoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for managing digital graphometric signatures face security vulnerabilities due to the potential for unauthorized access to stored data and dependency on specific acquisition devices with varying sensor capabilities, which can compromise the safety and efficiency of signature recognition.
Innovation Solution
A system and procedure for managing digital signatures that securely registers and recognizes signatures by discretizing them into fragments with associated biometric data, translating this data into symbolic reference codes stored on a secure server, making it difficult to trace the original signature and ensuring compatibility across a range of electronic devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If digital signatures are stored on archiving servers with detailed node characteristics, then signature recognition accuracy is improved, but security against unauthorized access and hacking is worsened
Solution Approach 1:
The patent divides the digital signature into multiple discrete nodes with specific coordinates and characteristics. Each node is processed and stored separately, allowing the system to reconstruct and recognize the signature without storing the complete signature image. This segmentation enables accurate recognition while reducing security risks associated with storing complete signature data.
Solution Approach 2:
The patent extracts only the essential biometric parameters from the signature (node coordinates, arrival times, pressure values) and stores these extracted features rather than the complete signature. This extraction process removes unnecessary information that could be used for tracing or hacking while retaining sufficient data for accurate recognition.
2Reliability
If signature acquisition systems use multiple sensor types for comprehensive biometric data collection, then recognition reliability is improved, but device complexity and compatibility issues are worsened
Solution Approach 1:
The patent designs the signature acquisition system to work with multiple types of devices (smartphones, tablets, graphic tablets, computers) by identifying and utilizing biometric parameters that can be detected by various sensor types. The system accommodates different sensor capabilities while maintaining consistent recognition performance across diverse devices.
Solution Approach 2:
The patent adapts the signature recognition process to work with different sensor capabilities by adjusting which biometric parameters are collected and how they are processed. The system can operate with varying levels of sensor precision and types, changing the parameter set based on device availability while maintaining recognition reliability.
