Transparent Display Authentication Pattern Forgery Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authenticating systems are vulnerable to hacking as the authentication pattern is stored in the authenticating device, allowing hackers to forge the pattern and gain unauthorized access.
Innovation Solution
An authenticating system that displays a first display pattern on a transparent display panel with a transmissivity pattern and a second display pattern on a background display panel, generating a sensing pattern that is compared to a reference pattern, preventing pattern forgery by using the transmissivity pattern as an identifier and adjusting gray-levels for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the authentication pattern is stored in the authenticating device, then the authentication process is simple and fast, but the system becomes vulnerable to hacking and pattern forgery
Solution Approach 1:
The patent extracts the authentication pattern from the authenticating device and displays it on a transparent display panel. This allows the pattern to be verified externally without storing it in the device, thereby preventing hacking while maintaining authentication functionality.
Solution Approach 2:
The transparent display panel acts as an intermediary between the authenticating device and the authentication pattern. It displays the pattern temporarily for verification purposes, eliminating the need for direct storage in the device while enabling external verification.
2Reliability
If a transparent display panel with transmissivity pattern is used, then pattern forgery is prevented through physical identification, but manufacturing complexity increases
Solution Approach 1:
The transparent display panel incorporates a transmissivity pattern with specific local optical properties. Different regions of the panel have different light transmission characteristics that form the authentication pattern, enabling security through physical identification while using standard display manufacturing techniques.

AI summary
An authenticating system includes an authenticating device, a background display device, a sensing device, and an authentication pattern checking device. The authenticating device displays a first display pattern on a transparent display panel including a transmissivity pattern. The transmissivity pattern includes a plurality of regions with different transmissivities. The background display device displays a second display pattern on a display panel to overlap the transparent display panel. The sensing device generates a sensing pattern by sensing an authentication pattern generated based on the transmissivity pattern, the first display pattern, and the second display pattern. The authentication pattern checking device performs authentication by checking whether the sensing pattern is consistent with an authentication reference pattern.
