Intermediary Device for Job Request Authentication and Cancellation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data handling protocols for imaging devices are inadequate in preventing data loss due to limited processing resources and time constraints, which can lead to unauthorized access and data breaches, as they struggle to determine whether job requests meet data handling policies efficiently.
Innovation Solution
Implementing a system where a computing device intercepts job requests, determines their authenticity and authorization by verifying digital signatures, and generates a cancellation request if they are not valid, thereby reducing processing resources utilized for non-authorized and non-authentic jobs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data handling protocols are implemented in imaging devices to verify job requests, then data security is improved, but processing resources are insufficient and time constraints increase
Solution Approach 1:
An intermediary device is introduced between the job request source and the imaging device. This intermediary verifies the authenticity and authorization of job requests using digital signatures before forwarding them to the imaging device, thereby maintaining data security without burdening the imaging device's limited processing resources.
Solution Approach 2:
The complex verification process for data handling policies is extracted from the imaging device and relocated to a separate intermediary device. This extraction allows the imaging device to focus on its core printing function while the intermediary handles the computationally intensive security verification.
2Productivity
If imaging devices process all incoming job requests, then productivity is maintained, but unauthorized access and data breaches increase
Solution Approach 1:
The intermediary device performs preliminary verification of job requests using digital signatures before they reach the imaging device. This preliminary action filters out unauthorized requests in advance, ensuring that only authenticated jobs are processed by the imaging device, thus maintaining productivity while preventing unauthorized access.
Solution Approach 2:
The system applies preliminary anti-action by verifying the authenticity of job requests before processing. The intermediary checks digital signatures and validates authorization tokens in advance, preventing potentially harmful unauthorized requests from entering the printing system.
3Measurement precision
If verification of digital signatures is performed in imaging devices, then authorization accuracy is improved, but processing time increases
Solution Approach 1:
The time-consuming digital signature verification process is performed by an intermediary device rather than the imaging device. The intermediary handles the computationally intensive cryptographic operations, while the imaging device simply receives pre-verified jobs, thereby maintaining high authorization accuracy without significant verification time delays affecting printing throughput.
