Image Processing Apparatus Reprint Feature for Confidential Data Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems for printers lack efficient mechanisms to prevent the removal of defective printed materials containing confidential information, which can lead to unauthorized disclosure.
Innovation Solution
An image processing apparatus and method that compares sample and read image data to determine abnormalities, stores inspection results, and instructs reformation of images based on identified defects, ensuring that defective prints are properly discarded without being removed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If defective printed matter is discarded without taking out, then data privacy is protected, but operator convenience deteriorates
Solution Approach 1:
The system enables self-service by automatically detecting defective printed matter through image reading and comparison, storing it in the storage unit, and triggering automatic reprint without requiring operator intervention for manual discarding. The reprint specifying unit automatically identifies and reprints defective pages based on stored image data.
Solution Approach 2:
The system implements feedback by reading the discarded defective printed matter, comparing it with the master image, storing the defect information, and using this feedback to automatically trigger reprinting of the defective pages, creating a closed-loop quality control system.
2Reliability
If reprint function is added to prevent unauthorized disclosure, then data privacy is improved, but device complexity increases
Solution Approach 1:
The image reading unit serves multiple functions: it reads printed matter for quality inspection, reads discarded defective matter for identification, and provides image data for comparison and storage. The storage unit stores both master images and defective printed matter images, serving both quality control and reprint identification purposes.
Solution Approach 2:
The system merges the quality inspection function and the unauthorized disclosure prevention function into a unified system. The same image reading, storage, and comparison mechanisms are used for both detecting defective print quality and identifying discarded matter for automatic reprinting.
Data Source
AI summary
An image processing apparatus includes a memory and circuitry. The memory is configured to store a result of inspection. The inspection includes: comparison of a sample image data and a first read image data that is data of an image formed on a recording medium and read; and determination whether the image indicated by the first read image data is abnormal. The memory is configured to store the result of inspection in association with the image determined as an abnormal image. The circuitry is configured to receive second read image data from a discarding apparatus. The circuitry is configured to specify image data according to which an image is formed, based on the abnormal image stored in the memory and the second read image data received. The circuitry is configured to instruct formation of the image according to the image data specified.
