Cloud Print ID Segmentation for Security Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cloud print services lack the ability to perform security printing and aggregation management for print jobs due to the absence of user IDs unique to individual organizations, as they only manage user identification information within their own system.
Innovation Solution
An information processing system that obtains first identification information from a user for authentication to an image forming apparatus, sends this information to a print service system to establish a logical printer, and sets second identification information within the print service system, allowing the extraction and output of the first identification information from received print data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cloud print services use independent user IDs for authentication, then user authentication in the cloud print service is enabled, but the image forming apparatus cannot perform security printing or aggregation management using organization-unique user IDs
Solution Approach 1:
The patent segments user identification into two distinct parts: cloud print service user ID (for cloud authentication) and organization-unique user ID (for security printing and aggregation management). This segmentation allows each system to use the appropriate identifier without conflict, resolving the contradiction between cloud authentication and organization-specific security requirements
Solution Approach 2:
The patent embeds the organization-unique user ID within the print data transmitted from the cloud print service to the image forming apparatus. The print data structure contains both the cloud user ID and the nested organization user ID, enabling the image forming apparatus to extract and use the organization-unique identifier for security printing and aggregation management while maintaining cloud service authentication
2Ease of operation
If cloud print services manage only their own user identification information, then the print service system is simple to operate, but security printing and aggregation management cannot be performed
Solution Approach 1:
The patent performs preliminary action by having the image forming apparatus send its supported authentication method information to the cloud print service in advance. This allows the cloud print service to prepare and include the appropriate organization-unique user ID in the print data before transmission, ensuring that security printing and aggregation management capabilities are available without complicating the cloud service operation
Solution Approach 2:
The patent introduces print data as an intermediary carrier that transports organization-unique user ID information from the cloud print service to the image forming apparatus. This intermediary mechanism enables information transfer without requiring the cloud print service to directly manage or understand organization-specific authentication systems, maintaining operational simplicity while enabling security features

AI summary
An information processing system includes a setting unit and an identification information extracting unit. The setting unit obtains first identification information that is identification information of a user in an information system that performs first authentication, the identification information being input by the user for user authentication to an image forming apparatus connected to the information system, sends setting information including the first identification information to a print service system that performs second authentication, thereby establishing a logical printer in which the setting information is set in the service system, and sets, as identification information of a person who uses the logical printer, second identification information that is identification information of the user in the service system. The extracting unit receives, from the service system, print data to be printed by the image forming apparatus, and extracts and outputs the first identification information set in the received print data.
