Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing utilization management systems face issues of inconvenience due to the need for physical key exchange, increased security risks from Internet-based communication, and lack of user verification, particularly in managing access to facilities and vehicles.
Innovation Solution
A utilization management system utilizing Near Field Communication (NFC) for secure permit transmission, face authentication, and conditional access control, including a utilization control device, imaging device, and management device to verify and authorize user access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If RFID readers transmit read information to the server via the Internet, then the system enables remote server management and facility access control, but the security risk is increased due to data transmission over the Internet
Solution Approach 1:
The patent introduces an intermediary device (gateway or proxy server) between the RFID readers and the remote server. This intermediary receives data from RFID readers locally and selectively transmits only necessary information to the remote server, thereby reducing security risks associated with direct Internet transmission while maintaining remote management capabilities
Solution Approach 2:
The patent extracts sensitive information from the data transmission stream by having RFID readers store only essential access control data locally, while transmitting minimal information to the remote server. This extraction of necessary data from the complete information set reduces the security risk surface while maintaining system functionality
2Reliability
If a room key is lent out and returned at the reception desk, then the system enables centralized key management and facility access control, but the user convenience is reduced due to the need to stop at the reception desk for key exchange
Solution Approach 1:
The patent implements self-service functionality where users can automatically obtain and return room keys through RFID readers at designated locations without manual intervention from reception staff. The system automatically validates user credentials, issues keys, and tracks key returns, enabling users to complete key exchange independently while maintaining centralized management
Solution Approach 2:
The patent performs preliminary actions by pre-registering user credentials and facility access rights in the system before actual key exchange occurs. This pre-configuration enables automatic key issuance and validation, eliminating the need for manual key management at the reception desk while maintaining centralized control
3Ease of operation
If the system only uses RFID tag reading for access control, then the operation simplicity is maintained, but the user verification capability is insufficient to confirm whether the user is an authorized user
Solution Approach 1:
The patent merges multiple verification methods including RFID tag reading, facial recognition, and user credential validation into a unified access control system. The RFID reader works in conjunction with imaging devices and authentication servers to perform comprehensive user verification, maintaining operational simplicity through integrated automated processing while significantly improving verification accuracy
Data Source
AI summary
The present invention reduces security risk while improving the convenience, and further to limit predetermined uses of a usage target object to only authorized users. When a utilization control device (1) receives a restriction on use lift request from a user terminal (4) via Near Field Communication (63), it verifies a signature included in this request with a public key set in own device (1), and when the verification is established and conditions on use of a use permit included in this request are satisfied, it lifts a first restriction on use of a vehicle (5) (door lock, key box (10) lock). Further, when the first restriction on use is released, it performs face authentication using image data including an image of the user's face in the seat imaged by a camera (2) and the face authentication information included in this request, and if the face authentication is established, it lifts a second restriction on use of the vehicle 5 (engine start lock).
