Server Print Data Sharing via Access Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing location-free printing systems face difficulties in sharing registered print data between users, limiting convenience in data access and collaboration.
Innovation Solution
A server apparatus that generates and manages sharing access codes for print data, allowing users to share and access print data across a network, enabling secure and controlled sharing between registered users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access control is performed using registered user ID only, then security is maintained, but sharing capability deteriorates
Solution Approach 1:
The access control mechanism is segmented into two independent parts: user ID-based authentication for security verification, and sharing access code-based authorization for sharing control. This allows the system to maintain security through user ID verification while enabling sharing through separate access codes that can be distributed to multiple users without compromising the original security model
Solution Approach 2:
A sharing access code is introduced as an intermediary element between the registered user and the print data. This code acts as a mediator that enables third-party access without exposing the user ID or compromising the original authentication mechanism. The sharing access code serves as a bridge that allows controlled sharing while maintaining the security boundary established by user ID-based access control
2Reliability
If print data is restricted to registered users only, then security is improved, but ease of operation deteriorates
Solution Approach 1:
Instead of requiring physical presence at a specific MFP or direct user ID authentication for shared data, the system creates a copy of the access authority through sharing access codes. These codes can be distributed to multiple users who can then access the print data at any connected MFP without needing the original user ID, significantly improving operational convenience while maintaining security through code verification
3Adaptability or versatility
If sharing access code function is added, then sharing capability is improved, but device complexity increases
Solution Approach 1:
The server apparatus performs multiple functions using the same basic infrastructure: it generates sharing access codes, stores them in the database, verifies them during access, and manages their lifecycle (creation, storage, verification, deletion). This multi-functional approach allows the system to provide comprehensive sharing capabilities without proportionally increasing complexity, as the same core components handle multiple aspects of the sharing process
Data Source
AI summary
According to an embodiment, a server apparatus includes a storage unit and a control unit. The storage unit correlates print data to a user ID of which a user registers the print data, and stores the correlated print data. The control unit performs controlling such that when the control unit receives a preparation instruction of a sharing access code from a display operating unit, the control unit correlates the sharing access code to a print data designated among the print data registered by the user, and causes the correlated result to be stored in the storage unit. When the control unit receives designation of the sharing access code from the display operating unit, the control unit reads out information relating to the print data correlated to the sharing access code from the storage unit, and causes the read-out information to be displayed on the display operating unit.
