Solution Overview

Problem

Vulnerable documents such as birth certificates, land titles, and university degrees lack advanced anti-counterfeiting measures, making them susceptible to fraud as they do not have uniformity in format or security features, and existing security features can be easily duplicated by skilled counterfeiters.

Innovation Solution

A sticker with a chip and memory is applied to these documents, encoding data that is also displayed on the document, and this data is included in a blockchain for easy authentication using widely-available tools, allowing for reliable verification of authenticity and integrity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If basic security features (watermarks, fibers, guilloche printing) are used in documents, then manufacturing cost and complexity are reduced, but security against counterfeiting is insufficient as skilled counterfeiters can duplicate these features

Engineering Contradiction:
Improvesecurity against counterfeitingVSAvoiddocument structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent embeds a chip within a sticker that is applied to the document surface. The chip contains memory and processing capabilities nested within the sticker structure, creating a layered security system where the sticker itself can be visually inspected while the chip provides electronic verification, resolving the contradiction between simple document structure and high security

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The sticker acts as an intermediary between the document and verification systems. It contains a chip that mediates authentication by storing cryptographic credentials and enabling verification through smartphone applications, providing robust security without requiring complex modifications to the underlying document structure

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If advanced anti-counterfeiting measures (chips, biometric encoding) are implemented in all identity documents, then security is improved, but manufacturing cost and complexity increase significantly

Engineering Contradiction:
Improvesecurity against counterfeitingVSAvoiddocument production
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

Instead of implementing advanced security features in all documents, the patent applies security stickers selectively to vulnerable documents that require enhanced protection. This partial application approach provides high security where needed while avoiding the cost and complexity of universal implementation, resolving the contradiction between security improvement and manufacturing ease

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The sticker with chip is a relatively low-cost component compared to embedding chips directly in documents. It can be applied post-manufacturing to existing documents, allowing secure enhancement without expensive reissuance of entire document batches, thus resolving the contradiction between security and manufacturing cost

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Measurement precision

If uniform security features are implemented across all document types, then verification consistency is improved, but adaptability to different document formats and requirements is reduced

Engineering Contradiction:
Improveverification consistencyVSAvoiddocument format flexibility
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The sticker with chip serves multiple functions across different document types (birth certificates, land titles, university degrees, etc.). The same basic sticker design and verification mechanism work universally across various document formats, providing consistent verification while adapting to different document requirements through configurable chip content, resolving the contradiction between verification consistency and format flexibility

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A method for authenticating a certificate includes placing a sticker having a chip integrated therein onto the certificate. The chip includes a memory having information identifying the sticker and particular information that is on the certificate. An association is created between the information identifying the sticker and the certificate. This information is stored on a block chain.
