Image Processing and Forming Device Security Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems with image forming and processing devices operate independently, leading to inadequate security collaboration, where data erased in one device can still be stored in a reprintable form in the other, compromising overall system security.
Innovation Solution
A system where the image processing device and image forming device communicate to synchronize security settings, with a communication unit providing security information and a selection unit choosing the appropriate security type based on received information, ensuring unified security levels across both devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the image processing device and image forming device operate independently with separate security settings, then each device can maintain its own security policies, but the overall system security is compromised because data erased in one device can still be stored in the other
Solution Approach 1:
The patent merges the security management of the image processing device and image forming device by establishing a communication mechanism between them. The image processing device transmits security setting information to the image forming device, and both devices coordinate their security actions (such as simultaneous data erasure) to ensure unified system security, resolving the contradiction between independent operation and system-wide security protection.
Solution Approach 2:
The patent implements a feedback mechanism where the image processing device sends security setting information to the image forming device, which then adjusts its security operations accordingly. This feedback loop ensures that both devices maintain consistent security levels, preventing the scenario where data is erased in one device but retained in the other, thus improving overall system reliability.
2Ease of operation
If the image processing device stores print job data for potential reprinting, then user convenience is improved, but security is weakened when the image forming device erases data
Solution Approach 1:
The patent applies dynamics by making the data retention policy flexible and conditional. The image processing device dynamically adjusts whether to retain print job data based on security settings received from the image forming device. When high security is required, the image processing device deletes data even if reprinting was previously possible, thus balancing user convenience with security requirements through dynamic decision-making.
3Reliability
If the image forming device implements secure data erasure, then data security is improved, but system-wide security is reduced when the image processing device retains data
Solution Approach 1:
The patent implements a feedback mechanism where the image forming device communicates its security settings and data erasure status to the image processing device. The image processing device then synchronizes its data retention and erasure operations based on this feedback, ensuring that secure erasure in one device is matched by corresponding actions in the other, thereby achieving system-wide security without excessive complexity.
