Image Processing Device Invisible Information Embedding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing technologies lack effective methods for embedding invisible information that can be detected only under specific conditions, such as infrared light, to prevent falsification of printed documents.
Innovation Solution
An image processing system and method that extracts text information from print data based on set extraction conditions, converts it into invisible information, and embeds this information into the print data, making it detectable only under specific observation environments, such as infrared light, while maintaining the appearance of the original text under visible light.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If invisible information is embedded in print data to prevent falsification, then document security and reliability are improved, but the complexity of the image processing device and processing methods increases
Solution Approach 1:
The patent applies preliminary action by embedding invisible information into the print data during the image processing stage before actual printing occurs. The image processing device converts original information into invisible information and incorporates it into the print data in advance, so that when the document is printed, the security features are already embedded and can be verified later without requiring additional processing equipment or steps at the time of printing or verification.
2Reliability
If text information is converted to invisible information for security purposes, then document integrity verification is improved, but the ease of operation and user accessibility deteriorates
Solution Approach 1:
The patent uses an intermediary approach by introducing a specialized verification device that can detect the embedded invisible information. The ordinary user can still interact with the document normally using visible light, while the intermediary verification device (equipped with infrared or other specialized sensors) translates the invisible information into visible verification results, thus maintaining ease of operation for general users while enabling integrity verification when needed.
3Measurement precision
If extraction conditions are set for text information on a display screen, then precision of information extraction is improved, but the time required for processing and setup increases
Solution Approach 1:
The patent applies preliminary action by allowing users to pre-configure extraction conditions (such as color, position, or content criteria) on the display screen before printing. These conditions are stored and automatically applied during the image processing stage, so that when printing is initiated, the system quickly extracts the relevant text information according to the pre-set conditions without requiring time-consuming manual configuration at the moment of printing.

AI summary
An image processing device includes an input device and circuitry. The input device inputs data. The circuitry converts text information to be printed included in the data to generate converted information and outputs data for image formation including the converted information.
