Electronic Security Image Generation for Document Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for creating secure documents are slow, expensive, and unsuitable for electronic production, as they require specialized printers and are not effective for generating security images that are invisible to the naked eye but visible upon copying.
Innovation Solution
A method and system for electronically generating a security image using sets of parallel lines at specific angles and densities, allowing alphanumeric characters to be converted into invisible-on-normal-view security elements that become visible upon copying or with a specialized viewer, suitable for standard printers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If specialized printers and imprinted paper are used to create secure documents, then document security is improved, but production speed and cost-effectiveness deteriorate
Solution Approach 1:
The patent replaces the mechanical imprinted paper system with an electronic security image generation system. Instead of using specialized printers and imprinted paper, the invention creates security images electronically using standard printing capabilities, thereby maintaining security while improving production speed and cost-effectiveness.
Solution Approach 2:
The patent changes the parameters of document creation from physical imprinted paper to electronic security images with specific line densities and angles. By adjusting these parameters, the system achieves both security and efficiency, allowing standard printers to produce secure documents that were previously requiring specialized equipment.
2Reliability
If specialized printers and imprinted paper are used to create secure documents, then document security is improved, but production cost deteriorates
Solution Approach 1:
The patent replaces the mechanical imprinted paper system with an electronic security image generation system. This substitution eliminates the need for expensive specialized printing equipment while maintaining security features, thereby reducing production costs.
Solution Approach 2:
The patent uses standard, inexpensive printing materials and equipment to create security images that provide the necessary security features. Instead of relying on expensive specialized paper and printers, the system uses affordable electronic image generation and standard printing capabilities.
3Reliability
If specialized printers and imprinted paper are used to create secure documents, then document security is improved, but the complexity of the system deteriorates
Solution Approach 1:
The patent replaces the complex mechanical imprinted paper system with a simpler electronic security image generation system. This substitution reduces system complexity by eliminating specialized printing equipment and imprinted paper handling, while maintaining security through electronic image processing.

AI summary
A system for generating secure documents includes a station for generating a plain document and a security image generator that generates a security image. The security image is then incorporated into the plain document. Each security image consists of a plurality of secure elements, each secure element being defined by two sets of parallel lines. Each secure element defines an alphanumeric character or other unique image that is visible under certain conditions, i.e., when inspected through a viewer. The technique can also be used to provide security images on a web page as a means of indicating that the web page is genuine.
