Prioritizing User Selection Items for Quick Login Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Quick login methods for user authentication in image processing devices can lead to accidental selection of the wrong user, resulting in operational errors, such as incorrect scanning or printing operations, due to the lack of password input requirements and prioritization of user identification information.
Innovation Solution
A processing device that uses a user registrator, storage device, user authenticator, terminal information acquirer, and nearby terminal determiner to prioritize user selection items on the authentication screen based on matching terminal identification information from nearby portable communication terminals, ensuring that the correct user is selected for authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If quick login is used to simplify user authentication operations, then ease of operation is improved, but reliability deteriorates due to accidental selection of wrong user
Solution Approach 1:
The system performs preliminary actions by acquiring terminal identification information before displaying the user authentication screen, and prioritizes the display of the correct user's selection item based on this pre-acquired information. This preliminary identification reduces the risk of accidental wrong user selection during quick login.
2Productivity
If user identification information is prioritized on the authentication screen to enable quick login, then productivity is improved, but reliability worsens due to potential data loss from wrong user selection
Solution Approach 1:
The system provides feedback by prioritizing the display of the correct user's selection item based on terminal identification information, guiding the user to select the intended user without requiring time-consuming password input. This feedback mechanism maintains both speed and reliability by reducing selection errors.
3Reliability
If password input is required for secure authentication, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The system enables self-service authentication by automatically acquiring terminal identification information and prioritizing the correct user's selection item on the authentication screen. This allows users to perform quick login without manual password input while maintaining reliability through automated user identification.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution reduces the number of operational errors by prioritizing the correct user's selection item on the authentication screen, thereby minimizing accidental logins as another user and ensuring intended operations are performed correctly.
Implementation Method 1
a terminal information acquirer that performs wireless communication with the portable communication terminal carried by a nearby user to acquire the terminal identification information of the portable communication terminal
Data Source
AI summary
The number of operational errors where a user unintentionally logs in as another user in quick login is reduced.A processing device capable of user authentication includes a user registrator that receives registration of terminal identification information of a portable communication terminal as one piece of personal information associated with a user, a storage device that stores the personal information for each user, a user authenticator that displays a selection item related to a registered user on a user authentication screen, and performs authentication of the user in response to a selection, a terminal information acquirer that performs wireless communication with the portable communication terminal carried by a nearby user to acquire the terminal identification information of the portable communication terminal, and a nearby terminal determiner that determines whether the terminal identification information acquired matches the terminal identification information included in the personal information of the nearby user. In a case where the terminal identification information acquired matches the terminal identification information of the nearby user, the user authenticator displays a user selection item of the nearby user on the user authentication screen, in a manner such that the user selection item of the nearby user has a priority higher than the user selection item of another user.
