Server Authentication Code Segmentation for Device Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for registering multiple information devices, such as image forming devices, are cumbersome due to the need for multiple authentication codes, which can be difficult to manage and require tedious setup processes.
Innovation Solution
A server system that generates a single PIN code for authenticating multiple information devices, simplifying the registration process by allowing a single code to be used across multiple devices and managing device IDs and serial numbers efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single authentication code is used for one information device, then authentication security is maintained, but the complexity of managing multiple authentication codes increases and setup becomes tedious
Solution Approach 1:
The authentication code is segmented into two parts: a common first authentication code stored in the server for multiple devices, and a unique second authentication code stored in each information device. This segmentation allows the server to authenticate multiple devices using the first code while each device maintains its unique second code for device-specific authentication, thereby reducing management complexity while preserving security.
2Reliability
If multiple authentication codes are stored in the server for multiple information devices, then each device can be authenticated securely, but the setup process becomes tedious and time-consuming
Solution Approach 1:
The server performs preliminary actions by storing the first authentication code in advance for multiple information devices before actual authentication occurs. When a device needs authentication, the server already has the first code ready, and the device provides its pre-stored second code, enabling rapid authentication without time-consuming setup procedures.
3Reliability
If a sales person registers multiple information devices individually, then each device is properly authenticated, but the registration process becomes difficult to manage
Solution Approach 1:
The first authentication code serves a universal function for multiple information devices, allowing a single code to authenticate any device in the group. This multi-functionality enables sales persons to register multiple devices efficiently without needing to manage separate authentication codes for each device, significantly improving ease of operation while maintaining authentication accuracy through the complementary second code.

AI summary
A server may store one or more accounts. Each account may be associated with an authentication code and a total number of information devices that are allowed to be registered. The authentication codes may be provided to users for registering information devices. The information device may transmit a connection request, including an entered authentication code, to a server. Upon receiving the connection request, the server may determine whether to register the particular information device. The server may determine whether the information device is allowed to be registered based on registerable information, which is associated with an account that is associated with the received authentication code and which represents a remaining number of information devices that are allowed to be registered using the associated authentication code. If the information device is allowed to be registered, the server may send authentication information to the information device, so it may transmit state information.
