Print Ticket Authentication UI for Secure V4 Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of V4 printer drivers, there is a limitation in displaying a pop-up UI for secure printing after a print instruction is given, especially when password input is omitted, due to the complexity of inter-process communication required by the XPS filter or V4 printer driver, which hinders user authentication prompts.
Innovation Solution
A program is provided that displays a pop-up UI for authenticated printing by receiving a print ticket and activating a print time-activated application, allowing for user input of a password before printing commences, even if the password is initially omitted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a V4 printer driver is used to improve security and convenience, then security is improved, but it becomes impossible to display a pop-up UI prompting users to input passwords after a print instruction is given
Solution Approach 1:
The system performs preliminary actions by attaching authentication information to the print job before transmission to the image forming device. The authentication UI is prepared and integrated into the print dialog in advance, allowing the authentication process to be initiated seamlessly when the print job is submitted, rather than requiring complex post-print interventions.
Solution Approach 2:
The patent introduces an intermediary mechanism where the authentication UI is embedded within the existing print dialog framework. This intermediary approach allows the authentication prompt to be displayed through the established print driver interface without requiring separate complex inter-process communication mechanisms, thus maintaining security while enabling user interaction.
2Reliability
If secure printing with password authentication is implemented, then security is improved, but the system becomes more complex due to required inter-process communication for pop-up display
Solution Approach 1:
The patent merges the authentication UI functionality with the existing print dialog interface. By combining these functions into a single integrated interface, the system eliminates the need for separate complex inter-process communication mechanisms to display authentication prompts, thereby reducing overall system complexity while maintaining security functionality.
Solution Approach 2:
The print dialog interface is designed to serve multiple functions: it handles both the standard printing controls and the authentication prompt display. This multi-functional design allows the same interface structure to manage both routine print operations and security authentication, reducing the need for additional specialized components and simplifying the overall system architecture.
3Ease of operation
If the authentication UI is displayed after print instruction is given, then user authentication is enabled, but the control framework limitation prevents pop-up display without special expansion
Solution Approach 1:
The authentication UI is prepared and integrated into the print dialog in advance, before the print instruction is finalized. This preliminary integration allows the authentication prompt to be displayed naturally as part of the print submission process, eliminating the need for post-print pop-up mechanisms that would require complex framework expansions.
