Image Processor Batch Copying Password Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for copying confidential documents with embedded passwords require cumbersome password entry for each document, especially when multiple documents with different passwords need to be copied or scanned, leading to user inconvenience.
Innovation Solution
An image processor that extracts password, attribute, and page information from source documents, allowing for batch copying or scanning by matching password and attribute information, reducing the need for repeated password entry by permitting copying based on attribute and page count settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If password information is embedded in each confidential document to prevent copying, then document security is improved, but user operation complexity increases when copying multiple documents with different passwords
Solution Approach 1:
The system merges the password authentication process across multiple documents by detecting password information from previously authenticated documents and applying it to subsequent documents with matching attribute information, eliminating the need for repeated password entry while maintaining security
Solution Approach 2:
The system performs preliminary password authentication on the first document of a group, stores the authenticated password information, and uses this pre-acquired information to automatically authenticate subsequent documents with the same attribute information, avoiding redundant authentication steps
2Reliability
If password entry is required for each document copy, then authentication security is maintained, but processing time increases
Solution Approach 1:
The system combines multiple authentication operations into a single authentication event by detecting password information from previously authenticated documents and reusing it for documents with identical attribute information, thereby maintaining security while reducing total authentication time
Solution Approach 2:
The system copies password information from previously authenticated documents and applies it to subsequent documents with matching attributes, enabling rapid authentication without re-entering passwords while maintaining the security integrity of each document
3Productivity
If attribute information is used to permit batch copying, then copying efficiency is improved, but system complexity increases
Solution Approach 1:
The system applies local quality by using attribute information (such as document type, classification, or metadata) as a localized identifier to determine whether batch copying permission should be granted, allowing efficient batch processing while keeping the complexity management focused on specific document properties rather than overall system complexity

AI summary
An image processor includes an image reading unit that reads source documents and converts read data into image data, an extracting unit that extracts password information and attribute information from the image data of each of the source documents read by the image reading unit, a password inputting unit that inputs the password information, a password determining unit that determines whether or not the password information inputted by the password inputting unit matches the password information extracted by the extracting unit, and a permitting unit that permits a source document to be subjected to image processing, if the attribute information of the source document is identical to the attribute information included in the source document of which the password determining unit has determined that there is a match between the inputted password information and the extracted password information.
