QR Code Document Security Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses lack a comprehensive method to restrict and notify document providers about the execution of copying, scanning, or facsimile jobs based on the confidentiality details embedded in the original image, failing to ensure secure management of highly confidential documents.
Innovation Solution
An information processing apparatus and document management method that utilize a QR code to indicate permission or prohibition of jobs related to a document, where the QR code is detected from the original image, and if permitted, the job is executed while notifying the provider via email, ensuring secure execution and notification of job status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If copying, scanning, or facsimile jobs are restricted based on code detection from original images, then document confidentiality and security are improved, but the complexity of the system increases due to code detection and provider notification mechanisms
Solution Approach 1:
A QR code containing control information is attached to the original image in advance before any copying, scanning, or facsimile operations. This preliminary encoding of permission/prohibition data enables the system to automatically enforce document security restrictions without requiring complex real-time authorization workflows, thereby improving reliability while managing system complexity.
Solution Approach 2:
A QR code serves as an intermediary carrier that embeds control information (permission or prohibition flags) within the original image. This intermediary mechanism simplifies the system architecture by replacing complex authentication systems with a straightforward code-detection-and-enforce workflow, resolving the contradiction between security reliability and system complexity.
2Reliability
If a QR code is attached to the original image to indicate job permissions, then document confidentiality management is improved, but the ease of operation deteriorates due to the additional step of code attachment and detection
Solution Approach 1:
The QR code containing control information is merged with the original image itself, creating a unified document package. This merging eliminates the need for separate metadata files or database lookups, allowing the system to enforce confidentiality management automatically through simple image processing operations, thereby maintaining reliability while improving ease of operation.
Solution Approach 2:
The original image itself carries its own control information through the embedded QR code, enabling self-service confidentiality management. The document contains its own permission/prohibition instructions, eliminating the need for external authorization systems or manual configuration, thus improving both confidentiality management and operational simplicity.
3Loss of information
If the provider is notified via email when a job is executed, then accountability and traceability are improved, but the loss of time increases due to notification processing and email communication
Solution Approach 1:
An automated feedback mechanism is implemented where the system detects job execution and immediately sends email notifications to the document provider. This feedback loop ensures complete accountability tracking by automatically recording and communicating all document operations, improving information retention while minimizing time loss through automation rather than manual processes.
Solution Approach 2:
The manual or semi-automatic notification process is replaced with an automated electronic mail system triggered by job execution detection. This substitution eliminates the need for human intervention in the notification workflow, improving accountability tracking completeness while reducing the time required for provider notification through automated electronic communication.
Data Source
AI summary
The information processing apparatus includes an input device, a communication device, and a control device. The image indicated by the document is input to the input device. The communication device communicates with other electronic apparatuses. The control device includes a processor, and the processor functions as a controller by executing a control program. The controller detects a code indicating permission or prohibition of a job related to the document and a provider of the document from the input image, and determines the permission or prohibition of the job related to the document and the provider of the document on the basis of the detected code, and, in a case where it is determined that the job related to the document is permitted, executes the job related to the document, and notifies the provider that the job related to the document has been executed via the communication device.
