Server-Mediated Mutual Authentication for Valet Parking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In valet parking services, there is a challenge in verifying the authenticity of the attendant and the customer, which can lead to security issues and mistrust between the two parties.
Innovation Solution
An authentication method and system that uses a server to communicate with customer and attendant terminals, where a trigger signal initiates the exchange of identification information, allowing both parties to verify each other's authenticity through a matching authentication notice.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual valet parking is used without authentication system, then ease of operation is improved, but reliability deteriorates due to inability to verify authenticity of customer and attendant
Solution Approach 1:
The server acts as an intermediary between the customer terminal and attendant terminal, facilitating mutual authentication without requiring direct complex interaction between the two parties. The server mediates the exchange of identification information and coordinates the authentication process, simplifying the overall system architecture while ensuring reliable verification of authenticity.
Solution Approach 2:
The system implements feedback mechanisms where the server sends authentication notices to both the customer terminal and attendant terminal based on the matching of identification information. This feedback loop confirms successful authentication to both parties, ensuring reliability while maintaining operational simplicity through clear confirmation signals.
2Reliability
If authentication code is transmitted with security considerations, then reliability is improved, but loss of time increases due to verification processes
Solution Approach 1:
The server transmits the first identification information to the customer terminal in advance before the actual authentication event occurs. This preliminary action allows the customer to have the authentication code ready, reducing the verification time at the moment of authentication while maintaining security through the pre-established identification information.
Solution Approach 2:
The system allows the authentication process to proceed rapidly by having the attendant terminal directly input the identification information and immediately compare it with the stored first identification information. The server quickly processes the matching and sends authentication notices, rushing through the verification process to minimize time loss while maintaining security checks.

AI summary
The present disclosure provides a technique that enables a customer who intend to receive a service and an attendant in charge of the customer to verify each other's authenticity. An authentication method of the present disclosure comprises transmitting a trigger signal from the customer terminal to the server, transmitting first identification information to the customer terminal, and displaying the first identification information on the customer terminal. The authentication method of the present disclosure also comprises accepting input of second identification information into the attendant terminal, transmitting the second identification information from the attendant terminal to the server, collating the second identification information transmitted from the attendant terminal with the first identification information transmitted to the customer terminal, and transmitting authentication notice to the customer terminal and the attendant terminal in response to equality between the first identification information and the second identification information.
