Server Device Authentication Key Generation for Restricted Item Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for managing access to restricted items in multi-unit residential buildings require resident presence for unlocking doors, and stored service numbers for authentication, which limits flexibility and security.
Innovation Solution
A server device that processes person-under-restriction related information and usage related information to generate authentication key information, which is used to authenticate input key information and unlock restricted items, thereby managing access flexibly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If service numbers are stored in the server device for authentication, then authentication can be performed, but the system loses flexibility and requires constant storage of service numbers
Solution Approach 1:
The server device generates and stores authentication key information in advance based on person-under-restriction related information before actual authentication is needed. This preliminary generation allows flexible authentication without requiring constant storage of service numbers during operation, resolving the contradiction between maintaining authentication capability and achieving system flexibility.
2Reliability
If resident presence is required for unlocking operations, then security is maintained, but delivery personnel cannot access restricted items without resident presence
Solution Approach 1:
The server device acts as an intermediary that generates authentication key information based on person-under-restriction related information. This intermediary mechanism allows delivery personnel to authenticate and access restricted items without requiring physical presence of the person under restriction, while maintaining security through verified authentication keys.
3Reliability
If service numbers are always stored for authentication, then authentication works, but device complexity and storage requirements increase
Solution Approach 1:
The patent extracts the authentication key information generation function from the traditional service number storage approach. Instead of storing and managing service numbers for authentication, the system extracts and stores only the necessary authentication key information generated from person-under-restriction related information, simplifying storage management while maintaining authentication functionality.

AI summary
A server device is provided comprising: at least one processor, wherein the at least one processor is configured to execute a computer readable instructions so as to: receive at least one of person-under-restriction related information related to a person under restriction whose usage of a restricted item is restricted or usage related information related to usage of the restricted item by the person under restriction instructed by an instructor; and generate authentication key information generated based on at least one of the received person-under-restriction related information or the received usage related information, the authentication key information being used to authenticate input key information generated based on predetermined input-key generation rule information and the authentication key information and input to the restricted item by the person under restriction, and to release restriction of the restricted item.
