QR Code Access for Secure Scanned File Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for obtaining scanned files from multi-function peripherals (MFPs) require dedicated applications and setup, and printed access information can be vulnerable to unauthorized access.
Innovation Solution
A system that includes a reading apparatus to upload scanned files to a server, generating and displaying a QR code for accessing the upload destination, allowing a portable terminal to read and download the file without direct communication with the MFP, using a signed URL with authentication information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a dedicated application is used to communicate directly with the MFP for obtaining scanned files, then the file transfer can be achieved, but the system complexity increases and requires setup configuration
Solution Approach 1:
The patent introduces a server as an intermediary between the MFP and the information terminal. The MFP uploads scanned files to the server, and the server provides access information (such as QR codes) to the terminal for file retrieval. This eliminates the need for direct communication and dedicated applications between MFP and terminal, simplifying the system while maintaining file transfer capability.
2Ease of operation
If access information is printed by the MFP for file retrieval, then the setup operation is eliminated, but the security against unauthorized access is compromised
Solution Approach 1:
The patent implements dynamic access codes that are temporary and automatically expire after a certain period or after use. Instead of static printed access information, the system generates time-limited access codes (such as QR codes) that are provided to authorized users. This dynamic approach maintains ease of operation while significantly improving security, as expired codes cannot be used for unauthorized access.
3Productivity
If the MFP directly transmits files to the information terminal, then the transfer is direct, but the access information may be obtained by third parties
Solution Approach 1:
The server acts as a secure intermediary that receives files from the MFP and provides controlled access to authorized terminals. Instead of direct MFP-terminal communication that exposes access information, the server mediates the transfer by hosting files temporarily and providing secure, time-limited access codes. This maintains transfer efficiency while protecting against third-party interception and unauthorized access.

AI summary
A reading apparatus comprises: an upload unit that uploads to a server a scanned file; and a display control unit that obtains an access code which is generated and for accessing an upload destination of the scanned file and displays the generated access code on a display unit. A portable terminal comprises: a reading unit that reads the displayed access code; an access unit that obtains information indicating an upload destination of the scanned file based on the reading and, using the obtained information, accesses the upload destination; and a download unit that downloads the scanned file from the upload destination. The information indicating the upload destination of the scanned file includes authentication information related to an access of the upload destination of the scanned file.
