Certificate Surface Authentication for Counterfeit Copy Detection
Find Innovative SolutionsGenerate Solutions
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, as they rely solely on character and symbol recognition, allowing false positives.
Innovation Solution
An information processing device and method that photographs a certificate and determines 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 verify the authenticity of the physical certificate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If character and symbol recognition is used for authenticity determination, then the process is simple and fast, but counterfeit certificates with identical information cannot be distinguished from genuine ones
Solution Approach 1:
The patent segments the authentication process into two independent parts: (1) character and symbol recognition for basic verification, and (2) surface appearance analysis for counterfeit detection. By dividing the authentication system into these separate functional modules, the patent maintains fast processing through character recognition while adding reliable counterfeit detection through surface feature analysis without significantly increasing overall complexity.
Solution Approach 2:
The patent introduces surface appearance characteristics as an intermediary element between the certificate and the authentication system. Instead of directly verifying only information content, the system uses surface features (texture, reflectivity, hologram patterns) as an intermediate verification layer that provides additional authentication evidence without interfering with the speed of character recognition.
2Device complexity
If only information content verification is performed, then the authentication process is simple, but it cannot detect counterfeit certificates with copied information
Solution Approach 1:
The patent transitions authentication from a two-dimensional information content verification to a three-dimensional approach by incorporating surface appearance characteristics. This dimensional expansion allows the system to verify both the information layer and the physical layer of the certificate, enabling counterfeit detection while maintaining relatively simple processing through standard image analysis techniques.
3Reliability
If surface appearance analysis is added to authentication, then counterfeit detection improves, but processing time and complexity increase
Solution Approach 1:
The patent applies partial action by selecting only the most critical surface appearance characteristics for analysis (texture, reflectivity, hologram presence) rather than analyzing all possible surface features. This selective approach provides sufficient counterfeit detection capability while minimizing processing time and computational complexity, avoiding excessive analysis that would slow down authentication.

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.
