Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current handwritten signature authentication systems face challenges in accurately distinguishing genuine signatures from copied ones, particularly in behavioral characteristics data comparison methods, leading to potential security breaches when third parties mimic signature patterns.
Innovation Solution
A time-division segment block-based handwritten signature authentication system that divides handwritten signatures into segments by a predetermined time slice, extracting and comparing characteristics information from these segments to enhance authentication accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If behavioral characteristics data comparison method is used for handwritten signature authentication, then authentication capability is provided, but security is compromised when third parties copy signature patterns
Solution Approach 1:
The handwritten signature is divided into multiple segments based on time-division, where each segment corresponds to a specific time slice during the signing process. This segmentation allows the system to analyze temporal characteristics of different parts of the signature separately, making it difficult for copyists to replicate the precise temporal patterns of each segment, thereby enhancing security while maintaining authentication capability.
2Measurement precision
If traditional handwritten signature authentication is used, then authentication process is simple, but recognition accuracy is insufficient to distinguish genuine signatures from imitated ones
Solution Approach 1:
The signature is segmented into multiple time-based segments, and correlation information is calculated between adjacent segments to capture temporal dynamics. This approach enhances recognition accuracy by analyzing the temporal relationships within the signature without requiring complex additional hardware, as the segmentation is performed on existing signature data.
Solution Approach 2:
The system extracts multiple parameters including spatial coordinates, pressure, and temporal characteristics from each segment. By changing the parameters analyzed from simple image matching to multi-dimensional behavioral characteristics (position, pressure, time correlations), the system achieves higher recognition accuracy while maintaining reasonable system complexity.
3Reliability
If image comparison method is used for handwritten signature authentication, then authentication is straightforward, but security is compromised when signature images are copied
Solution Approach 1:
Instead of comparing the entire signature image at once, the system segments the signature based on time-division and compares correlation information between segments. This makes image copying ineffective because the temporal relationships between segments cannot be replicated by static image copying, thereby enhancing security while keeping the process relatively simple.
Solution Approach 2:
The system extracts specific behavioral characteristics (temporal correlations, pressure patterns, segment relationships) from the signature process, separating these critical security-related features from the visual appearance of the signature. This extraction allows the system to ignore the visual image that can be copied while focusing on the behavioral patterns that are difficult to replicate.
