Solution Overview

Problem

Existing printing systems do not allow guest users without accounts to authorize output data, leading to security risks and increased economic burdens due to the need for dedicated equipment and infrastructure.

Innovation Solution

A system that enables guest users to receive temporary print authorization through a Personal Identification Number (PIN) code, allowing them to print data without requiring a registered account, while ensuring security by limiting access to their own print requests.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If dedicated equipment and infrastructure are provided for guest users, then security is improved, but device complexity and economic burden increase

Engineering Contradiction:
ImprovesecurityVSAvoidequipment infrastructure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces an authentication server as an intermediary component that manages authentication for both registered and guest users. This server acts as a mediator between the image forming apparatus and users, handling PIN code verification and authorization without requiring dedicated infrastructure for each user type. The authentication server consolidates security management functions, improving security while avoiding the need for complex separate systems for guest users.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The image forming apparatus is designed to handle multiple user types (registered users and guest users) through a unified authentication mechanism. The apparatus can authenticate both users with accounts and guests with PIN codes using the same authentication server, eliminating the need for separate dedicated equipment for different user categories. This multi-functional approach maintains security while reducing device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If registered accounts are required for all users, then security is improved, but ease of operation deteriorates for guest users

Engineering Contradiction:
ImprovesecurityVSAvoiduser accessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent segments the authentication mechanism into two independent pathways: one for registered users using account credentials and another for guest users using PIN codes. This segmentation allows guest users to access printing services without creating registered accounts, improving ease of operation. Meanwhile, registered users continue to use their accounts for enhanced security, so overall system security is maintained through this segmented approach.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The authentication server serves as an intermediary that handles both registered user authentication and guest user PIN verification through a unified interface. This intermediary manages the complexity of supporting multiple authentication methods while presenting a simple, consistent user experience. Guest users can obtain and use PIN codes without account registration, improving accessibility while the authentication server maintains security through centralized control.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If temporary authorization is provided without accounts, then ease of operation is improved, but security deteriorates

Engineering Contradiction:
Improveguest user accessibilityVSAvoidsecurity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary authentication actions by verifying PIN codes against the authentication server before allowing any printing operations. This preliminary verification ensures that even though guest users don't have registered accounts, their temporary authorization is validated against a secure centralized system. The PIN code mechanism itself acts as a preliminary security measure, providing ease of operation while maintaining security through pre-verification of authorization credentials.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The authentication server provides feedback mechanisms to verify PIN code validity and track authentication attempts. This feedback system ensures that temporary guest authorization is properly validated and monitored, preventing unauthorized access. The server can provide feedback on authentication success/failure and maintain logs of guest printing activities, thereby maintaining security while allowing temporary access for ease of operation.

Inventive Principle:
Principle #23Feedback

AI summary

An information processing system includes one or more information processing apparatuses. The information processing system includes an output data reception part that receives, via a network, output data or output target data; a storage process part that associates data identification information with the output data and stores them in a data storage part when the output data reception part receives the data identification information for the output data or output data generated based on the output target data or a request to issue the data identification information; a notification part that notifies of the data identification information via a network; and a transmission part that transmits, via a network, the output data associated with the user identification information received via a network.
