Viewing Apparatus with Iris Authentication for Secure Hidden Image Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display systems fail to restrict access to hidden images, as unauthorized users can obtain polarization lenses to view protected content, and are limited to specific image display apparatus, making it impossible to handle hidden images on non-apparatus media like printed paper.
Innovation Solution
A viewing apparatus with a transmission unit, identification information obtaining unit, and processor for authentication and light adjustment, ensuring only legitimate users can view hidden images by authenticating users based on iris recognition and adjusting light passage through a shutter mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If polarization lens is used to view hidden image, then hidden image can be viewed, but unauthorized users can also obtain the lens and view the hidden image
Solution Approach 1:
The system divides the viewing solution into two separate components: a polarization lens (optical component) and an authentication mechanism (control component). The authentication unit verifies user identity before enabling the lens to function, so that merely possessing the lens is insufficient for viewing hidden images. This segmentation separates the optical function from the security function, allowing the lens to be distributed while maintaining security through centralized authentication.
Solution Approach 2:
The authentication unit acts as an intermediary between the user and the polarization lens. It verifies user credentials (such as iris recognition or other identification methods) and only permits the lens to adjust light for hidden image viewing when authentication succeeds. This intermediary layer prevents unauthorized access while allowing legitimate users to view hidden images, resolving the security vulnerability of the conventional system.
2Reliability
If exclusive image display apparatus is used, then hidden image can be securely viewed, but images on other media like printed paper cannot be handled
Solution Approach 1:
The polarization lens is designed to be a universal optical component that can work with any image medium (display screens, printed paper, photographs, etc.). The authentication unit provides the security control function that makes the system adaptable to different media. This universality allows the same lens to securely view hidden images across multiple platforms and formats, eliminating the limitation of exclusive image display apparatus while maintaining security through the authentication mechanism.
3Reliability
If authentication processing is added, then only legitimate users can view hidden image, but system complexity increases
Solution Approach 1:
The authentication unit operates autonomously to verify user credentials and control lens functionality without requiring complex external security systems. The lens itself contains or is associated with the authentication capability, allowing it to self-regulate access based on verified user identity. This self-service approach provides robust security while minimizing additional system complexity, as the authentication function is integrated into the lens unit rather than requiring separate complex security infrastructure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables secure viewing of hidden images only by authorized users, regardless of the image medium, using iris recognition and encrypted user information from bar codes to control light adjustment, preventing unauthorized access.
Implementation Method 1
adjustment processing which adjusts light passing through the transmission unit to switch whether the hidden image can be viewed or not

AI summary
Disclosed is a viewing apparatus including a transmission unit having light transparency, through which an image is viewed, the viewing apparatus comprising: an identification information obtaining unit which obtains identification information to identify a user of the viewing apparatus; and a processor which performs: authentication processing which authenticates the user based on the identification information; judgment processing which judges whether a hidden image included in advance in the image can be viewed or not, based on a result of the authentication processing; and adjustment processing which adjusts light passing through the transmission unit to switch whether the hidden image can be viewed or not, based on a result of the judgment processing.
