Printing Apparatus Password Verification via Pre-stored Fixed Credential
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In reservation printing systems, users are required to enter a password multiple times, which is time-consuming and labor-intensive, while maintaining security by ensuring only authorized individuals can access password-protected print jobs.
Innovation Solution
A printing apparatus that includes a receiving unit for print data, a storage unit for password-protected print data, an operating unit for user instructions, and a display unit for password entry, allowing the apparatus to print data without requiring a user to re-enter a password if the pre-stored fixed password matches the job password, thus eliminating the need for multiple password entries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a password entry screen is displayed for each print job to maintain security, then security is improved, but user operation time and effort increase
Solution Approach 1:
The patent applies preliminary action by pre-storing a fixed password in the printing apparatus before the user needs to print. When a print job is received, the system automatically compares the job's password with the pre-stored fixed password, eliminating the need for the user to enter a password at the time of printing. This resolves the contradiction by maintaining security through password verification while eliminating user operation time.
Solution Approach 2:
The patent implements self-service by having the printing apparatus automatically perform password verification using a pre-stored fixed password without requiring user intervention. The system self-verifies the password against the print job and automatically proceeds to printing if the password matches, eliminating the need for users to manually enter passwords while maintaining security.
2Reliability
If multiple password entries are required to verify authorization, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-configuring the printing apparatus with a fixed password that is automatically used for verification. This eliminates the need for multiple manual password entries by the user, as the system automatically compares the pre-stored password with the job password, thereby improving ease of operation while maintaining security.
Solution Approach 2:
The patent implements self-service by having the printing apparatus automatically perform authorization verification using a pre-stored fixed password without requiring user intervention. The system self-verifies credentials and automatically proceeds to printing if authorized, significantly improving ease of operation while maintaining security protocols.
3Ease of operation
If a fixed password is pre-stored in the printing apparatus, then ease of operation is improved, but security may be compromised
Solution Approach 1:
The patent applies the copying principle by using a fixed password that is copied or pre-stored in the printing apparatus memory. This pre-stored password is automatically compared with the password in the print job without requiring manual entry, improving ease of operation. The security is maintained through automatic verification rather than manual entry, and the system can log authentication events for auditing purposes.

AI summary
A printing apparatus includes a receiving unit which receives print data, an operating unit which receives a print instruction from a user, a display unit which displays a password entry screen for receiving a password entry from a user, and a printing unit which receives a print instruction from a user through the operating unit and prints print data without accepting a password through a password entry screen if a password added to the print data is matched with a fixed password and print data to be printed if a print instruction from a user is received through the operating unit, if the password added to the print data is matched with the fixed password, and if the password received through a password entry screen is matched with the password added to the print data.
