Viewing-Angle Security Features for Automated Document Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual verification of documents with viewing-angle-dependent security features is time-consuming, and existing electronic assistance systems lack a user-friendly, partially automated method for detecting and verifying these features.
Innovation Solution
A document design featuring two adjacent viewing-angle-dependent security features, where one feature provides a representation from a first viewing position and the other from a second position, allowing for efficient verification using a telecommunications device with an image camera, potentially including a smartphone, by moving the device parallel to the document and comparing recorded representations with reference images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual verification of viewing-angle-dependent security features is performed, then verification accuracy is maintained, but verification time increases significantly
Solution Approach 1:
The patent replaces the manual mechanical verification process with an automated electronic assistance system using an image camera and processor. The system captures images of security features at different viewing angles and automatically compares them with reference representations, substituting human visual inspection with electronic image processing while maintaining verification accuracy.
Solution Approach 2:
The system creates digital copies (images) of the viewing-angle-dependent security features using an image camera. These captured images are then processed and compared with reference representations stored in memory, enabling automated verification without requiring manual visual comparison of the actual physical features.
2Productivity
If electronic assistance systems are introduced for automated verification, then verification time is reduced, but system complexity increases
Solution Approach 1:
The verification system is designed to be universal and multi-functional. The image camera can capture security features from various viewing angles, the processor can handle multiple comparison operations, and the system can verify different types of documents. This multi-functionality reduces the need for multiple specialized devices, thereby managing complexity while maintaining high productivity.
Solution Approach 2:
The system incorporates self-service elements through automated image capture, automatic comparison with reference representations stored in memory, and automated verification results. The processor independently performs the comparison operations without requiring continuous human intervention, reducing operational complexity while improving verification efficiency.
3Measurement precision
If multiple reference representations are required for verification, then verification accuracy is improved, but the number of comparisons and processing time increases
Solution Approach 1:
Reference representations of security features at different viewing angles are pre-captured and stored in the system's memory before actual verification occurs. When verification is needed, the system simply compares captured images against these pre-stored references, eliminating the need to create reference images during verification and reducing processing complexity while maintaining accuracy.
