Image Reading Apparatus Permission Validation for Secure Data Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image reading apparatuses face challenges in securely managing and recording sensitive image data on external memories, as unprotected data can be leaked if the password-protected portable external memories are not properly managed, leading to unauthorized data recording and a proliferation of external memories.
Innovation Solution
An image reading system that includes a reading unit, a memory interface for external memory, a permission information obtaining unit, and a permission determining unit, which ensures that data is only recorded on external memories with valid permission information, preventing unauthorized access and data leakage by validating permission information before recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If password protection is implemented for external memories, then data security is improved, but the risk of unauthorized data recording and proliferation of external memories increases
Solution Approach 1:
The system performs preliminary actions by recording permission information on the external memory before allowing any data recording operation. The permission information is written in advance, and subsequent data recording operations are controlled based on this pre-established permission framework, preventing unauthorized recording without requiring continuous password verification.
Solution Approach 2:
Permission information acts as an intermediary between the user and the data recording process. Instead of directly requiring password authentication for each recording operation, the system uses permission information stored on the external memory as a mediator to control and manage data recording rights, simplifying the security mechanism while maintaining control.
2Reliability
If permission information validation is implemented, then unauthorized data recording is prevented, but device complexity increases
Solution Approach 1:
The external memory itself provides the permission information validation service by containing embedded permission information that the image reading apparatus reads and verifies automatically during data recording operations. This self-service approach eliminates the need for complex centralized authentication systems while maintaining secure data protection.
Solution Approach 2:
The permission verification function is extracted from the main data recording process and implemented as a separate, simple validation mechanism. The permission information is independently stored on the external memory and verified separately before allowing data recording, simplifying the overall system architecture by dividing functions into distinct modules.
3Adaptability or versatility
If multiple external memories are allowed for data storage, then data accessibility is improved, but data leakage risk increases
Solution Approach 1:
The system implements feedback mechanisms where permission information on external memories is validated and verified before allowing data recording. This feedback loop ensures that only authorized external memories can receive data, maintaining data accessibility across multiple devices while preventing leakage through unauthorized storage locations.

AI summary
An image reading apparatus includes: a reading unit; a memory interface unit; a permission information obtaining unit; a permission determining unit; and a data recording unit. The reading unit reads an image. An external memory is removably connected to the memory interface unit and stores permission information. The permission information obtaining unit is configured to obtain the permission information from the external memory. The permission determining unit is configured to determine whether the obtained permission information is valid. The data recording unit is configured to record data corresponding to the image on the external memory connected to the memory interface unit if the obtained permission information is valid.
