Authentication Apparatus Dynamic Device Credential Assignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-function apparatuses require pre-stored card information, limiting their functionality when user authentication information is not registered in advance, and there is no method to assign device authentication information to portable devices without prior storage.
Innovation Solution
A function performing apparatus and portable device configuration that allows for user authentication and device authentication information registration, enabling the assignment of device authentication information even if not pre-stored, through near field communication and authentication memory management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If card information is stored in advance in a card, then authentication can be performed quickly, but the system cannot accept portable devices without pre-stored authentication information
Solution Approach 1:
The system performs preliminary authentication by requiring the user to manually input authentication information on the function performing apparatus. This preliminary action establishes trust before the system assigns device authentication information to the portable device, enabling future automatic authentication without pre-stored cards.
Solution Approach 2:
The function performing apparatus acts as an intermediary that bridges traditional card-based authentication and modern portable device authentication. It receives authentication information, verifies it, and then issues device authentication information that allows portable devices to authenticate themselves in subsequent connections.
2Reliability
If the system requires pre-stored authentication information, then security is maintained, but user convenience is reduced as users must prepare specific cards
Solution Approach 1:
The system enables self-service authentication by allowing the portable device to store and present its own device authentication information. The function performing apparatus issues this information after initial verification, eliminating the need for users to manually prepare or carry separate authentication cards.
3Adaptability or versatility
If device authentication information is assigned dynamically, then portable devices without pre-stored information can be used, but the system complexity increases
Solution Approach 1:
The authentication process is segmented into two distinct phases: initial authentication where the user manually inputs information on the function performing apparatus, and subsequent authentication where the portable device uses its stored device authentication information. This segmentation simplifies each individual step while enabling overall system flexibility.

AI summary
A function performing apparatus includes a function performing unit performing a specific function, a processor, and memory storing computer-readable instructions therein, the computer-readable instructions, when executed by the processor, causing the function performing apparatus to perform, in response to receiving a user authentication information when the user authentication information has been registered in an authentication memory, transitioning a state of the apparatus from a non-permission state to a permission state, registering, in the authentication memory, a device authentication information in association with the user authentication information upon establishing a first connection with a portable device, and transitioning the state of the apparatus from the non-permission state to the permission state when a second connection with the portable device is established and the device authentication information is obtained from the portable device.
