Image Decoloring Apparatus Password-Protected Difference Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image decoloring apparatuses face challenges in effectively extracting and managing characters and figures written with ink that decolor when heated, as they struggle to separate and protect confidential information from non-confidential data after the decoloring process.
Innovation Solution
An image decoloring apparatus with a reading section, storage section, heating section, and password-setting functionality that reads and stores image data before and after heating, extracts difference image data by comparing pre- and post-decoloring images, and sets passwords for the extracted data to maintain confidentiality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If image data is extracted and managed after decoloring process, then handwritten information can be separated from printed information, but confidential information may be exposed without proper access control
Solution Approach 1:
A password setting section is introduced as an intermediary mechanism between the difference extraction section and the stored image data. This mediator controls access to the extracted handwritten information by requiring authentication, thus preventing unauthorized access while allowing legitimate users to retrieve the separated information.
Solution Approach 2:
Password protection is set in advance for the stored image data before any access attempts. By preliminarily establishing access control mechanisms, the system ensures that confidential information remains protected from the moment it is extracted and stored, rather than attempting to secure it after potential exposure.
2Reliability
If password protection is implemented for extracted image data, then confidential information is protected, but access to legitimate data becomes more complex
Solution Approach 1:
The system automatically manages password protection for extracted image data without requiring manual intervention for each access request. The password setting section autonomously applies protection to stored data, and the authentication process is integrated into the data retrieval workflow, making the security mechanism transparent to users while maintaining ease of operation for legitimate access.
3Device complexity
If all image data is stored without differentiation, then storage management is simple, but confidential handwritten information cannot be protected
Solution Approach 1:
The difference extraction section automatically separates handwritten information from printed information by comparing image data before and after the decoloring process. This extracted difference image data is then stored with password protection, while other non-sensitive data can be managed separately without the same level of security measures, thus protecting confidential information without overly complicating overall storage management.
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
The apparatus efficiently decolors images formed with decolorable toner and ink, allowing for the extraction and management of handwritten data while ensuring high confidentiality by generating third image data only with a valid password, thus preventing unauthorized access to sensitive information.
Implementation Method 1
a first heating section configured to heat the sheet
Implementation Method 2
a reading section configured to read an image on a sheet to acquire image data

AI summary
An image decoloring apparatus includes a reader configured to read an image on a sheet to acquire image data, a storage section configured to store the image data acquired by the reader, and a first heater configured to heat the sheet. The apparatus further includes a difference extractor configured to extract difference image data based on first image data read from the sheet before it is heated by the first heater and second image data read from the sheet after it is heated by the first heater. The apparatus additionally includes a setting section configured to set a password required to access the difference image data.
