Solution Overview

Problem

Existing authenticity determination methods for digitized certificates, such as driver's licenses and passports, fail to distinguish between genuine certificates and counterfeit copies or images displayed on other devices, leading to false authenticity verification.

Innovation Solution

An information processing device and method that photographs a certificate and determines its authenticity based on the appearance of the certificate's surface, using methods such as reflected light intensity, area, shape, and hologram patterns, along with image processing techniques to analyze the surface characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If OCR process is used to extract characters and symbols from certificate image data for authenticity determination, then the verification process can be automated and performed quickly, but the system cannot distinguish between genuine certificates and counterfeit copies or images displayed on other devices

Engineering Contradiction:

Improveauthenticity verification speedVSAvoidauthenticity determination accuracy

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent segments the authenticity verification process into two independent parts: (1) OCR-based character and symbol extraction for rapid verification, and (2) surface appearance analysis for genuine certificate identification. This segmentation allows each method to specialize - OCR handles speed while surface analysis handles accuracy, resolving the contradiction between productivity and reliability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces surface appearance characteristics as an intermediary element that bridges the gap between automated verification and genuine authentication. By analyzing physical surface properties (texture, reflectivity, hologram patterns) that differ between real certificates and digital copies, the system achieves both automation and accuracy without compromising either productivity or reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If only character and symbol extraction is performed for authenticity determination, then the process is simple and fast, but it accepts counterfeit certificates that have identical information content as genuine

Engineering Contradiction:

Improveverification process simplicityVSAvoidcertificate authenticity detection precision

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent transitions from two-dimensional character recognition to three-dimensional surface analysis by examining physical properties such as texture, reflectivity, and hologram patterns. This dimensional shift enables the system to detect genuine certificates based on their physical characteristics rather than just their information content, thereby improving measurement precision while maintaining operational simplicity through automated image analysis.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Reliability

If surface appearance analysis is added to authenticate certificates, then genuine certificates can be distinguished from counterfeit copies, but the device complexity and processing requirements increase

Engineering Contradiction:

Improveauthenticity determination accuracyVSAvoidsystem structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a universal authentication system where a single image capture device performs multiple functions: it captures both the visual information content (for OCR processing) and the surface appearance characteristics (for genuine certificate identification). This multi-functionality reduces device complexity by eliminating the need for separate sensors or specialized equipment, while still achieving high reliability through combined analysis.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

The information processing device photographs a certificate and determines its authenticity. The information processing device includes a photographing means and a determination means. The photographing means photographs a certificate and generates a photographed image. The determination means determines authenticity of the certificate based on appearance of a surface of the certificate in the photographed image. When the certificate is determined to be true, the image of the certificate is registered with the information processing device.
