Solution Overview

Problem

Conventional printing apparatuses with admission printing functions lack robust security measures, allowing unauthorized access and printing when third parties accidentally or intentionally input correct passwords, leading to potential leaks of sensitive printing information.

Innovation Solution

The printing apparatus employs a dual verification system that requires both password and time-based admissions, where the user must input the password at a pre-assigned time, ensuring that only authorized users can initiate the printing process, and includes features to restrict data presentation and notify users of upcoming printing times to prevent unauthorized access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a single password verification system is used for admission printing, then the ease of operation is improved, but the security of printing information deteriorates

Engineering Contradiction:

Improveease of operationVSAvoidsecurity of printing information

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The single password verification system is segmented into multiple verification layers: first admission information (password) and second admission information (time stamp). This segmentation allows the system to maintain operational simplicity while enhancing security through multi-factor authentication, directly resolving the contradiction between ease of operation and security.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary actions by pre-registering both the first admission information (password) and second admission information (time stamp) before the actual printing operation. This preliminary setup enables the dual verification mechanism to function automatically during printing, providing enhanced security without complicating the user's printing process.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If a dual verification system with password and time-based admission is implemented, then the security of printing information is improved, but the device complexity increases

Engineering Contradiction:

Improvesecurity of printing informationVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system merges the password verification function and time stamp verification function into a single integrated admission managing section. This merging allows the dual verification system to operate with enhanced security while minimizing the increase in device complexity by consolidating multiple verification functions into one unified module.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The admission managing section is designed with multi-functionality, handling both first admission information (password) and second admission information (time stamp) verification within a single section. This universal design reduces device complexity by avoiding the need for separate verification modules for each authentication factor.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If printing data is always presented at the operator panel, then the ease of operation is improved, but the security of printing information deteriorates

Engineering Contradiction:

Improveease of operationVSAvoidsecurity of printing information

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The presentation of printing data at the operator panel is made dynamic rather than static. Data is conditionally presented based on verification results: only after successful first admission information input and only at the designated time for second admission information. This dynamic approach maintains ease of operation for authorized users while preventing unauthorized access.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system introduces an intermediary verification mechanism (time stamp verification by the admission managing section) between the user's access request and the presentation of printing data. This intermediary layer ensures that even if data is presented, it is only after proper authentication, thus maintaining both ease of operation and security.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

What is disclosed is a printing apparatus consisting: a memory section for memorizing plural printing data, and a first admission information and a second admission information corresponding to each of plural printing data; a first admission information inputting section for inputting an admission information corresponding to the first admission information; a second admission information inputting section for inputting an admission information corresponding to the second admission information; an admission information managing section for outputting a command of indicating to perform a printing process of a prescribed print data contained in said memory section, in case where an admission information inputted by the first admission information inputting section accords with the first admission information, and where an admission information inputted by the second admission information inputting section accords with said second admission information; and a print processing section for performing a printing process based on the command.
