Secure Document Registration With Decoy Barcodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing document security systems are vulnerable to high-quality forgeries, as advanced technologies enable the creation of undetectable counterfeit documents, posing risks to issuing organizations and individuals.
Innovation Solution
A system that creates and registers secure documents by associating a unique security barcode with the content, using decoy barcodes to enhance security, and verifies authenticity through a proprietary scanner or mobile device, ensuring only authorized access to the identifier barcode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional security features (watermarks, embedded threads, complex imaging) are used, then document security is improved to some extent, but high-quality forgeries can still be created that are undetectable even to experts
Solution Approach 1:
The patent transforms the security approach by changing from physical/document-based security features to digital parameter-based security. A unique identifier is assigned to each document and stored in a database, allowing verification through parameter matching rather than physical inspection. This resolves the contradiction by providing reliable verification without requiring complex physical security features that can be forged.
Solution Approach 2:
The patent replaces mechanical/physical security verification (inspecting watermarks, threads, imaging) with an electronic/digital verification system. A verification device captures an image of the barcode, extracts the unique identifier, and electronically compares it against the database. This substitution eliminates the need for experts to perform complex physical inspections, resolving the contradiction between security reliability and verification complexity.
2Ease of operation
If a simple barcode identifier is used, then document registration and verification are simplified, but the document becomes vulnerable to forgery and alteration
Solution Approach 1:
The patent merges the simplicity of barcode technology with the security of a centralized database system. The unique identifier is encoded in a simple barcode format for easy scanning, but its security value comes from being registered in and verified against a controlled database. This combination maintains ease of operation while ensuring reliability against forgery.
Solution Approach 2:
The patent introduces a database as an intermediary between the simple barcode identifier and the verification process. The barcode itself remains simple and easy to scan, but the database acts as a mediator that validates whether the identifier is legitimate. This intermediary layer preserves ease of operation while adding the necessary security against forgery.
3Reliability
If multiple barcodes including decoy barcodes are used, then security against forgery is enhanced, but the complexity of the security feature increases
Solution Approach 1:
The patent converts the potential harm of having multiple barcodes (increased complexity) into a benefit by using decoy barcodes as a security feature. The decoy barcodes appear to add complexity but actually serve to confuse potential forgers and verify the authenticity of the document through the verification system. The verification device is programmed to recognize the specific pattern and validate only the correct barcode, transforming structural complexity into a security advantage.
Data Source
AI summary
A method for creating a secure document, registering the secure document and verifying the authenticity of the secure document includes receiving a print object that has content. A security feature, including an identifier, is created and is associated with the content. The identifier may be a barcode. The barcode may represent a character string. The security feature may include the identifier barcode and a decoy barcode that is not associated with the content. The identifier barcode (or the character string represented by the barcode) and the content are transmitted to a database for storage. Once stored, the identifier and the content are considered to be registered. A print object that includes the security feature and the content is then transmitted to a printer for printing.
