Invisible Mark Reading with NIR Image Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reading devices provide only the final determination result of authenticity, making it difficult for users to verify the validity of the authenticity determination and limiting the accuracy of the process.
Innovation Solution
The reading device notifies the user with the raw NIR image data instead of the final determination result, allowing users to judge the validity of the authenticity determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the reading device provides only the final determination result, then the device complexity is reduced, but the user cannot verify the validity of the authenticity determination
Solution Approach 1:
The patent extracts the invisible image data from the complete authenticity determination process and presents it separately to the user. By taking out this intermediate information, users can verify the determination results themselves while the device maintains a clear functional structure that doesn't overwhelm the user with unnecessary complexity.
Solution Approach 2:
The patent segments the information flow into distinct parts: the invisible image reading process, the authenticity determination logic, and the result presentation. This segmentation allows users to see the intermediate invisible image data separately from the final determination, enabling verification while keeping the overall system manageable.
2Reliability
If the reading device displays the invisible image, then the user can verify the authenticity determination, but the ease of operation is reduced due to additional information processing
Solution Approach 1:
The patent introduces the invisible image as an intermediary element between the authenticity determination process and the final result. This intermediary provides users with verifiable information to assess reliability, while the system manages the complexity of presenting and processing this additional information through structured display methods.
3Measurement precision
If the reading device stores and notifies raw NIR image data, then the accuracy of authenticity determination is enhanced, but the loss of time for data processing increases
Solution Approach 1:
The patent performs preliminary action by reading and storing the invisible image data in advance, before the authenticity determination is completed. This allows the raw NIR image data to be readily available for user verification without requiring additional processing time when the user needs to verify the results, thus enhancing precision without significant time penalty.
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
This approach enhances the accuracy of authenticity determination by enabling users to verify the authenticity determination results directly and supports multiple-checks through stored NIR images.
Implementation Method 1
performing securement of originality, authenticity determination, and anti-forgery by embedding invisible information that is not visible to eyes in a document, and by reading the invisible information with invisible light such as infrared light

AI summary
A reading device (101) includes a light source (2), an imaging element (9), a controller (23), a correcting unit (22), and a notifying unit (25). The light source (2) is configured to irradiate an object with light. The imaging element (9) is configured to receive and read the light from the object. The controller (23) is configured to control a second reading operation of reading the object with an invisible image. The correcting unit (22) is configured to perform correction with respect to the invisible image. The notifying unit (25) is configured to notify an outside of at least the invisible image corrected.
