Print Job Authentication Data Removal for Reprint Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printing systems face reliability and security issues due to mismatches between the user who initiates a reprint and the user authenticated by the system, as the stored print job retains authentication information from the original user, leading to failed authentication and counting errors during reprinting.
Innovation Solution
An image processing apparatus is configured to communicate with a printing apparatus, transferring print jobs and deleting authentication information after print processing, ensuring that only the current user's authentication information is used for reprinting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the print job is stored with authentication information for reprinting, then the reprinting function is enabled, but the authentication reliability deteriorates due to user mismatch
Solution Approach 1:
The patent extracts and removes the authentication information from the stored print job data. When a print job is completed and stored for reprinting, the authentication information (username, password) is deleted from the stored data, preventing user mismatch issues during reprinting while maintaining the reprinting functionality
Solution Approach 2:
The patent performs preliminary deletion of authentication information when the print job is initially stored. By removing the authentication data at the time of storage rather than at the time of reprinting, the system proactively prevents authentication reliability issues before they can occur
2Ease of operation
If the authentication information is retained in the stored print job, then the reprinting can be performed smoothly, but the security deteriorates due to unauthorized access
Solution Approach 1:
The patent extracts and removes the authentication information from the stored print job data. When a print job is completed and stored for reprinting, the authentication information (username, password) is deleted from the stored data, preventing user mismatch issues during reprinting while maintaining the reprinting functionality
Solution Approach 2:
The patent introduces an intermediary authentication process where the system prompts the user to re-enter authentication information when initiating a reprint. This intermediary step ensures that the person performing the reprint is authorized, maintaining security while enabling smooth reprinting operations
Data Source
AI summary
An image processing apparatus and a control method is provided. The apparatus and method provides that, when a print job to be re-executed is stored, deletes authentication information required for an authentication function in a printing system from among print attributes included in the print job, and then stores the print job in the printing system.
