Augmented Reality System for Security Document Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for checking security documents are inefficient due to the large amount of information they contain, often resulting in incomplete verification within the time constraints of inspections, especially in high-pressure situations like border controls or airports, and existing automatic authentication systems primarily focus on security elements while neglecting other critical information.
Innovation Solution
An augmented reality system utilizing detection devices and control units in devices like data glasses, tablets, or smartphones to capture and verify various information types from security documents, including personal data, security features, and biometric data by comparing them with a database, enabling comprehensive and rapid verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If comprehensive inspection of all information in security documents is performed, then verification reliability is improved, but inspection time requirement increases beyond available time constraints
Solution Approach 1:
The patent divides the verification process into multiple stages: initial quick capture of key information (personal data, document type), followed by selective verification of security elements, and finally comprehensive checking only when anomalies are detected. This segmentation allows the system to maintain high reliability while adhering to time constraints by not uniformly applying full inspection to all documents.
Solution Approach 2:
The system performs partial verification on all documents (capturing and checking basic information) and excessive/comprehensive verification only when needed (when security elements show anomalies or document type requires it). This selective approach ensures that most routine checks are completed quickly while maintaining the ability to perform thorough verification when necessary.
2Loss of information
If manual inspection of all security document information is performed, then verification completeness is improved, but inspection efficiency decreases
Solution Approach 1:
The patent replaces manual mechanical inspection with an automated optical system using cameras and image processing algorithms. The system automatically captures document images, extracts information, and verifies security elements, eliminating the need for manual examination of each document while maintaining comprehensive verification of all information.
Solution Approach 2:
The system introduces an intermediary image processing and analysis layer between the document and the inspector. This intermediary automatically performs information extraction, validation, and security element verification, allowing the human inspector to focus on decision-making rather than manual information gathering, thus improving both completeness and efficiency.
3Measurement precision
If detailed knowledge of all document types and their security features is required, then verification accuracy is improved, but inspector training complexity and difficulty increase
Solution Approach 1:
The system makes the verification process self-service by embedding all document-specific knowledge and security feature criteria within the automated system itself. The system automatically identifies document type, selects appropriate verification parameters, and performs checks according to stored protocols, eliminating the need for inspectors to memorize detailed knowledge about numerous document types and their specific security features.
Solution Approach 2:
The patent creates a universal verification system that can handle multiple document types (passports, ID cards, visas) with a single device. The system automatically adapts its verification criteria based on detected document type, providing accurate verification for various document formats without requiring separate specialized knowledge or equipment for each document type.

AI summary
The invention relates to a method for checking a security document (10), the use of an augmented reality system (20) for checking a security document (10), and an augmented reality system (20). One or more pieces of information from the security document (10) are captured using an augmented reality system (20), in particular smart glasses. The one or more pieces of information are then checked by comparison with a database (40). Subsequently, one or more of the results of the check of the one or more pieces of information are stored and/or one or more of the results of the check of the one or more pieces of information are displayed using the augmented reality system (20).
