Scanner File Relay System for Secure Data Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scanner systems require complex setup and configuration for sharing, making it difficult for multiple users to access and utilize scanned image data without pre-installed software and settings.
Innovation Solution
A file providing method and system where a scanner uploads scanned data to a file relay apparatus on the Internet, storing it temporarily and displaying a URL for access, allowing users to download the data without preconfiguration, with automatic deletion after use or a set period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a scanner is shared through existing systems (PTL 1-4), then multiple users can access scanned data, but complex setup and configuration are required including pre-installed software and user registration
Solution Approach 1:
A file relay server acts as an intermediary between the scanner and user terminals. The scanner uploads scanned data to the file relay server, which then provides the data to users via URL access. This intermediary eliminates the need for complex pre-configuration on user terminals while enabling multiple users to access scanned data through simple web browser access.
Solution Approach 2:
The scanner automatically uploads scanned data to the file relay server without requiring user intervention for software installation or configuration. The system provides self-service functionality where the scanner handles the complex communication and data management tasks autonomously, while users simply access the data through provided URLs.
2Reliability
If scanned data is stored permanently on a server, then data availability is ensured, but data security risks and storage costs increase
Solution Approach 1:
The storage duration of scanned data is made dynamic rather than static. The file relay server automatically deletes scanned data after a predetermined period or after successful download by the user. This dynamic storage approach ensures data availability during the access period while minimizing security risks and storage costs by automatically removing data when no longer needed.
Solution Approach 2:
The system implements automatic discarding of scanned data after use or after a predetermined time period. The file relay server deletes the data from its storage, effectively discarding it to reduce security risks and storage requirements. This principle allows the system to maintain data availability during the access window while eliminating long-term storage risks.
3Adaptability or versatility
If scanned data is made accessible to multiple users, then scanner sharing is achieved, but data access control and security management become complex
Solution Approach 1:
The file relay server serves as an intermediary that simplifies access control. Instead of implementing complex authentication and authorization on the scanner or user terminals, the system uses simple URL-based access where the file relay server manages data distribution. This intermediary approach enables multi-user access while keeping security management simple through centralized control on the server side.

AI summary
A data file providing method includes a step of, by a scanner, uploading a data file generated by scanning process to a file relay apparatus on the Internet. The data file providing method includes a step of, by the file relay apparatus, storing the uploaded data file in a temporary storage location. The data file providing method includes a step of, by the scanner, displaying information indicating a uniform resource locator (URL) of the temporary storage location. The data file providing method includes a step of, by the file relay apparatus, transmitting the data file stored in the temporary storage location in response to a web access based on the URL.
