Image Forming Apparatus Barcode Position Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses lack effective security measures to ensure that image copying is only executed when user settings meet specific acceptance conditions, particularly in ensuring the correct positioning and orientation of two-dimensional barcode images within document images.
Innovation Solution
An image forming apparatus with a controller that converts document image data into two-dimensional barcode image data, randomly determines and stores the position and orientation of the barcode within the document image, and only proceeds with image formation after user confirmation through a touch panel, ensuring secure image processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If document image data is converted to two-dimensional barcode image data with random position and orientation, then security against unauthorized copying is improved, but device complexity increases due to the need for user interaction and verification
Solution Approach 1:
The controller performs preliminary conversion of document image data to two-dimensional barcode image data and determines the position and orientation information before the actual copying process. This preliminary action embeds security verification requirements in advance, ensuring that unauthorized copying is prevented while maintaining a structured workflow that manages complexity.
Solution Approach 2:
The system implements feedback by displaying the determined position and orientation information to the user through the touch panel and requiring user confirmation. This feedback loop verifies that the barcode image meets security requirements before proceeding with copying, enhancing security while using the existing touch panel interface to minimize additional complexity.
2Reliability
If user confirmation through touch panel is required for barcode position and orientation, then security is enhanced, but productivity decreases due to additional user interaction steps
Solution Approach 1:
The system applies partial verification by requiring user confirmation only for the position and orientation of the two-dimensional barcode image, not for the entire copying process. This selective verification approach enhances security for the critical security element while minimizing the impact on overall copying productivity.
Solution Approach 2:
The system uses the existing touch panel interface for user confirmation, leveraging the apparatus's own built-in interaction mechanism rather than requiring external devices or complex additional interfaces. This self-service approach using existing components reduces the productivity impact while maintaining security enhancement.
3Reliability
If two-dimensional barcode image data is stored with position and orientation information, then security control is improved, but loss of time increases due to verification processes
Solution Approach 1:
The controller determines and stores position and orientation information of the two-dimensional barcode image before the copying process begins. This preliminary determination eliminates the need for time-consuming verification during the actual copying operation, as the security parameters are pre-established and stored for efficient verification.

AI summary
An image forming apparatus includes an image forming section, an operation section, storage, and a controller. The image forming section forms a document image on a recording medium. The operation section includes a touch panel. The storage stores image data therein. The controller: converts document image data to two-dimensional barcode image data; randomly determines a position and an orientation of a two-dimensional barcode image to be located in a document image; stores to the storage the two-dimensional barcode image data together with information on the position and the orientation that are determined by the controller; and causes, only when a correct answer about the information on the position and the orientation is received from a user through the touch panel, preview display of the document image through converting the two-dimensional barcode image data back to the document image data.
