Money Handling Authentication Using Cloud-Based Two-Stage Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional money handling systems require users to remember and input additional authentication information such as secret questions and answers, making the authentication process cumbersome and unfriendly.
Innovation Solution
A money handling system that performs a first authentication using a user ID and password, followed by a second authentication using user information from a cloud-based authentication server, ensuring security without the need for users to remember additional information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two-factor authentication using voiceprint and secret questions is implemented, then security is improved, but ease of operation deteriorates because users must memorize and input additional authentication information
Solution Approach 1:
The patent introduces an authentication server as an intermediary that stores voiceprint information and secret questions. Instead of requiring users to memorize all authentication details, the server acts as a mediator that handles the verification process, allowing users to simply input their user ID and password while the server manages the additional authentication factors in the background
Solution Approach 2:
The system automatically performs the second authentication process using voiceprint and secret questions without requiring user intervention or memory. The authentication server autonomously verifies these factors after the initial login, eliminating the burden on users to remember additional information while maintaining security
2Reliability
If multiple authentication factors are required, then security is improved, but device complexity increases from the user perspective
Solution Approach 1:
The authentication process is segmented into two distinct phases: first authentication using user ID and password handled by the money handling apparatus, and second authentication using voiceprint and secret questions handled by the authentication server. This segmentation allows each component to specialize in one factor, simplifying the overall system architecture while maintaining multiple layers of security

AI summary
In order to ensure security related to money handling by using an easy user authentication method, a money handling system includes: a money handling apparatus to perform money handling; an input terminal configured to receive an input of authentication information for authenticating a user of the money handling apparatus, and transmit the authentication information to an authentication server which performs a first authentication process for the user based on the authentication information; and a control device including processing circuitry configured to receive user information of the user from the authentication server based on a result of the first authentication process, and perform a second authentication process for the user based on the user information.
