Embedding Security Data in Identification Document Line Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current identification systems lack effective methods to securely embed and verify sensitive information within physical and digital identification documents, making them vulnerable to fraud and unauthorized access.
Innovation Solution
The method involves embedding security information in background line patterns of identification documents using variable line lengths and gap widths, which can be machine-readable for verification and authentication purposes, allowing secure embedding and extraction of data such as names, dates of birth, or identification numbers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensitive information is embedded in background line patterns using variable line lengths and gap widths, then security and authenticity of identification documents is enhanced, but device complexity increases due to the need for specialized encoding and decoding mechanisms
Solution Approach 1:
The patent applies parameter changes by varying line lengths and gap widths in background line patterns to encode sensitive information. Different parameters (line length, gap width) are changed to represent different data values, enabling secure information embedding within the visual pattern while maintaining the aesthetic background design.
Solution Approach 2:
The background line patterns serve as an intermediary that carries encoded sensitive information. Instead of directly displaying sensitive data, the information is embedded within the line patterns that act as a mediator between the visual design and the security function, allowing verification without exposing the actual sensitive information.
2Reliability
If sensitive information is embedded in background line patterns, then verification and authentication capabilities are improved, but manufacturing precision requirements increase due to the need for accurate line segment encoding
Solution Approach 1:
The patent segments the background line patterns into discrete line segments with varying lengths and gaps. Each segment can independently encode information, allowing the system to distribute the encoding across multiple segments rather than requiring high precision across the entire pattern, thereby reducing overall manufacturing precision requirements.
Solution Approach 2:
Different regions of the line patterns have different local qualities - some areas have longer lines, others have shorter lines or larger gaps. This local variation in quality allows encoding of different data values in different locations, enabling information embedding while maintaining flexibility in manufacturing tolerances across different regions.
3Reliability
If machine-readable encoding is implemented in line patterns, then fraud detection capability is enhanced, but ease of operation decreases due to the need for specialized reading devices
Solution Approach 1:
The background line patterns serve multiple functions simultaneously: they provide the aesthetic background design, encode sensitive information, and enable verification/authentication. This multi-functionality allows the same visual element to serve both decorative and security purposes, reducing the need for separate verification components and simplifying the overall system operation.
Data Source
AI summary
A method for producing an identification article is described. The method includes associating one or more data items with one or more line patterns, where the line patterns include one or more line segments. A particular data item is associated with at least a subset of line segments and the particular data item corresponds to an attribute of a user of the identification article. The method further includes integrating the line patterns with graphical features of the identification article. The graphical features being discernable by a human eye and the subset of line segments is indiscernible by the human eye. The method includes identifying a region of the identification article that includes the subset of line segments associated with the particular data item and associating the particular line pattern with an identifying feature of the user.
