ID Document Pattern-Code Authentication Against Text Tampering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing document authentication methods are vulnerable to fraud and require complex, costly digital solutions that lack interoperability and privacy, making them susceptible to cyberattacks and difficult to integrate into existing systems.
Innovation Solution
A method for manufacturing identification documents that includes printing a background pattern with contrasting patterns over text fields, encoding a selected pattern portion into a machine-readable code, and using computer vision analysis for authentication, which enhances fraud detection by ensuring unique pattern matching for each document.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional security features (watermarks, holograms, specialized inks) are used for document authentication, then authentication capability is provided, but the documents become vulnerable to fraud because fake presentations can inherit these characteristics
Solution Approach 1:
The document is divided into two independent parts: identification information (name, number) and background pattern. The background pattern is further segmented into multiple contrasting patterns that are independently positioned. This segmentation allows the background pattern to serve as a unique security feature that cannot be easily copied, while the identification information can be changed without affecting the background pattern's authenticity.
Solution Approach 2:
Different regions of the document have different properties: the background pattern contains contrasting patterns with specific spatial frequencies and orientations that are unique to each document. The identification information is positioned in specific regions with defined contrast requirements. This local differentiation ensures that each document has unique security characteristics while maintaining readability of identification information.
2Reliability
If digital authentication technologies (digital signatures, blockchain, biometric verification) are introduced, then security and fraud resistance are improved, but implementation becomes complex and costly
Solution Approach 1:
Instead of using complex digital authentication systems, the patent creates a physical copy of the background pattern that serves as the authentication mechanism. The background pattern with its contrasting patterns is printed directly on the document in a way that creates a unique physical signature. This physical copy approach eliminates the need for digital signatures, blockchain, or biometric verification while providing equivalent security.
Solution Approach 2:
The patent uses simple, inexpensive printing techniques to create the background pattern rather than relying on expensive digital authentication infrastructure. The background pattern can be generated using standard printing equipment, making the system cost-effective and easily implementable without requiring complex digital systems.
3Reliability
If digital authentication technologies are integrated into existing systems, then authentication capability is enhanced, but compatibility and interoperability become challenging
Solution Approach 1:
The background pattern serves multiple functions simultaneously: it provides security authentication, serves as a visual design element, and can be detected by various imaging systems. The pattern's contrasting characteristics make it detectable by different types of imaging devices and analysis methods, ensuring compatibility across various authentication systems without requiring specialized digital infrastructure.
4Ease of operation
If generic authentication characteristics are used for a document type, then authentication process is simplified, but fake documents can inherit these characteristics making fraud detection difficult
Solution Approach 1:
The background pattern employs asymmetric contrasting patterns with specific spatial frequencies and orientations that are not uniform across the document. The patterns are positioned and oriented in non-repeating configurations that create a unique signature for each document. This asymmetry prevents fake documents from successfully copying the authentication characteristics while maintaining a simple authentication process.

AI summary
A method for manufacturing an identification document (1), comprising the following steps: • printing on the identification document (1) a background pattern (S1), the background pattern (10a, 10b) comprising contrasting patterns covering at least partially a text field (Tf1) of the identification document; • printing identification information (S2) in the text field (Tf1), the identification information comprising one or more characters; • selecting a part of a pattern (S3) from an image of the identification document (1), the part of the pattern (11a, 11b) comprising at least one character of the identification information and an overlapping part of the background pattern; • encoding the selected part of the pattern (11a, 12a) into a machine-readable code (S4); • printing (S5) the machine-readable code (13a) on the identification document (1).
