Authentication Code Verification for Secure Remote Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User operability is degraded when issuing scan data transmission instructions from a mobile terminal to an image forming apparatus, as users need to operate both devices, and there is a risk of misoperation leading to improper data transmission.
Innovation Solution
The data processing apparatus transmits an execution instruction to the image forming apparatus, which generates and displays an authentication code, and only executes the job if the transmitted authentication code matches the generated one, ensuring proper authorization and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If scan data transmission instruction is issued from mobile terminal to image forming apparatus, then remote operation capability is improved, but user operability is degraded because user needs to operate both devices
Solution Approach 1:
The patent combines the authentication code display function with the image forming apparatus and the authentication code input function with the mobile terminal, creating a unified remote operation flow where the user completes all operations on the mobile terminal without needing to physically interact with the image forming apparatus
2Ease of operation
If scan data transmission instruction is issued remotely from mobile terminal, then operation convenience is improved, but risk of misoperation increases leading to improper data transmission
Solution Approach 1:
The patent implements preliminary action by displaying the authentication code on the image forming apparatus before the user inputs it on the mobile terminal. This allows the user to verify the code matches the intended operation, preventing misoperations through advance confirmation
Solution Approach 2:
The system provides feedback by displaying the authentication code on the image forming apparatus, allowing the user to confirm the code before submission. This feedback mechanism ensures the user verifies the correct operation is being executed, preventing improper data transmission
Data Source
AI summary
A method performed by a data processing apparatus and an image forming apparatus includes transmitting, by the data processing apparatus, an execution instruction for a job to the image forming apparatus, generating, by the image forming apparatus, an authentication code corresponding to the transmitted execution instruction and displaying the authentication code or information representing the encrypted authentication code on a display unit of the image forming apparatus, transmitting, by the data processing apparatus, an authentication code to the image forming apparatus, and executing, by the image forming apparatus, a job corresponding to the transmitted execution instruction in a case where a predetermined condition is determined to be satisfied based on the transmitted authentication code and the generated authentication code.
