Dynamic Security Restriction for Secure Document Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for secure document output, such as image forming apparatuses, face restrictions when installed in public facilities or lacking proper security measures, leading to potential security risks and delayed document delivery if security requirements are not met.
Innovation Solution
A system that includes a server apparatus and image forming apparatuses connected via a network, where output is restricted if security requirements are not satisfied, but allows output if the recipient confirms removal of restrictions within a specified time period, ensuring secure document delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If output restriction is imposed due to security requirements, then security reliability is improved, but document delivery time increases
Solution Approach 1:
The patent implements dynamic security restriction management where the output restriction is not fixed but can be changed based on recipient confirmation. The system transitions from a static restricted state to an enabled state within a specified time period T when the recipient confirms, allowing the security level to adapt dynamically while maintaining overall security reliability.
Solution Approach 2:
The patent applies preliminary action by specifying a time period T in advance for the recipient to confirm document output. This predetermined time window allows the system to prepare for potential output while maintaining security, balancing the need for timely delivery with security requirements through advance planning.
2Object-affected harmful factors
If output restriction is imposed on apparatus without security measures, then security risk is reduced, but document accessibility decreases
Solution Approach 1:
The patent introduces a confirmation mechanism as an intermediary between the security restriction and the output operation. The recipient's confirmation acts as a mediator that bridges the gap between security requirements and accessibility needs, allowing documents to be output only when authorized while maintaining security for unauthorized cases.
Solution Approach 2:
The patent changes the security parameter state based on recipient confirmation. When the recipient confirms within time period T, the security parameter transitions from restricted to enabled, allowing the same apparatus to serve both secure and accessible functions dynamically without requiring physical or structural modifications.
Data Source
AI summary
A system includes a transmission apparatus that transmits data, and an output apparatus that outputs the received data. Output of the data is restricted if the output apparatus does not satisfy a predetermined security requirement. If a time period for outputting the data is specified, a confirmation is made with a recipient as to whether to permit removal of the restriction within the time period, and a response thereto is obtained. The output apparatus outputs the data if the response obtained from the recipient indicates removal of the restriction.
