Terminal Security Control via Sub-Processing Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processing systems on terminal devices often interrupt operations due to potential security issues, denying processing when any sub-operation poses a security risk, rather than isolating and mitigating the problem within a safe range.
Innovation Solution
A processing control system that includes a monitoring unit to assess the security status of terminal devices and a control unit to manage processing based on this status, allowing sub-processing operations to proceed if the security issue is contained, using a combination of TCP/IP and short-range communication software updates to ensure secure data transfer and reading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If processing is interrupted when any sub-processing operation has a potential security problem, then security reliability is improved, but productivity deteriorates
Solution Approach 1:
The patent segments the processing into multiple sub-processing operations and evaluates security status for each individually. The control unit determines security status for each sub-processing operation separately, allowing selective execution based on individual security assessments rather than blocking all operations when any single one has issues.
Solution Approach 2:
The patent applies local quality by allowing different sub-processing operations to have different security statuses and execution states. Some sub-operations can proceed while others are blocked based on their specific security conditions, creating a differentiated security approach rather than a blanket restriction.
2Object-affected harmful factors
If all sub-processing operations are blocked when one has security issues, then security risk is reduced, but operational efficiency deteriorates
Solution Approach 1:
The patent extracts the problematic sub-processing operation from the overall processing flow and isolates it for separate security evaluation. By identifying and separating the specific sub-operation with security issues, the system can block only that particular operation while allowing other safe operations to continue executing.
Solution Approach 2:
The patent applies partial action by selectively blocking only the necessary sub-processing operations that have security issues rather than blocking the entire processing flow. This partial restriction maintains security while preserving as much operational efficiency as possible through selective execution.
3Reliability
If security monitoring is performed on all terminal devices, then security coverage is improved, but system complexity increases
Solution Approach 1:
The patent implements a universal security monitoring mechanism that can evaluate multiple sub-processing operations across different terminal devices using the same control framework. The monitoring unit and control unit provide multi-functional security assessment capabilities that scale across the system without requiring device-specific complex implementations.

AI summary
A processing control system includes: at least one terminal device that is used by at least one user; a monitoring unit that monitors a security status of the at least one terminal device; and a control unit that controls, in a case where the security status which relates to executing processing instructed from the at least one user does not meet a condition, the processing including plural sub-processing operations on the at least one terminal device, execution of each of the sub-processing operations on the at least one terminal device based on the security status of the at least one terminal device.
