Facial Recognition Printing via Mobile Terminal Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming techniques require users to input a password at the apparatus, restricting their movement and causing inconvenience, as they cannot leave the device until the printing process is completed.
Innovation Solution
A method where a print job and user ID data are sent to an image forming apparatus, which uses facial recognition to authenticate the user through a mobile terminal, allowing printing to commence while the user is being recognized, enabling private output of printed matters without the need for continuous user presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If password input is required at the image forming apparatus, then security is improved, but user convenience deteriorates as users cannot leave the device
Solution Approach 1:
The user's mobile terminal performs preliminary authentication actions by sending the print job ticket to the image forming apparatus before the user arrives. The system waits for the mobile terminal's access in advance, so when the user presents their face at the device, the authentication process is already prepared and can be completed instantly without requiring the user to wait or input anything at the apparatus.
2Loss of time
If facial recognition is implemented, then authentication speed is improved, but device complexity increases
Solution Approach 1:
The mobile terminal acts as an intermediary that handles the complex authentication logic. The terminal sends the print job ticket containing user ID data to the image forming apparatus, and the apparatus uses this pre-sent data to perform rapid facial recognition authentication without needing complex embedded authentication systems.
3Measurement precision
If the system waits for mobile terminal access, then user identification accuracy is improved, but printing time increases
Solution Approach 1:
The system performs preliminary actions by waiting for and receiving the print job ticket from the mobile terminal in advance. This pre-authentication step ensures accurate user identification before the user arrives at the apparatus, so when the user presents their face, the printing can start immediately without delay.

AI summary
An image forming method includes: sending a print job and a print job ticket including user ID data from a terminal to an image forming apparatus and sending the print job ticket to a mobile terminal; receiving the print job ticket by the image forming apparatus; waiting for an access from a mobile terminal having the user ID data using a wireless communication in a specified range from the image forming apparatus; authenticating for accessing the print job ticket in the image forming apparatus using the user ID data; acquiring a facial image of a user in front of the image forming apparatus in response to the authentication; recognizing a face of an owner of the print job ticket in the acquired facial image to cause the image forming apparatus to print the image data; and printing the image data while the facial image is being recognized.
