Provisional Identification Linking for Virtual Currency Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional network systems require users to register personal information to obtain second identification information, which is inconvenient for users not interested in the associated services, preventing them from enjoying electronic value benefits.
Innovation Solution
A network system that allows users to utilize electronic value without registering personal information by linking first and second identification information, generating a provisional second identification information if the latter is not associated with personal information, and managing electronic value for both services through a server and terminal apparatuses connected via a network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users are required to register personal information to obtain second identification information, then system security and service management are improved, but user convenience and ease of access to electronic value are deteriorated
Solution Approach 1:
The identification system is segmented into two types: first identification information (device-based, no registration required) and second identification information (user-based, requires registration). This segmentation allows users to access electronic value immediately using device identifiers while providing an option for enhanced security and service through voluntary personal registration.
Solution Approach 2:
The system introduces an intermediary mechanism where first identification information serves as a temporary placeholder that can be linked to second identification information. This intermediary approach allows users to start using electronic value without full registration, then optionally complete the process by linking to personal information for enhanced security and service management.
2Adaptability or versatility
If personal information registration is mandatory for electronic value usage, then service management and user verification are improved, but user accessibility and system simplicity are deteriorated
Solution Approach 1:
The system dynamically adapts its verification requirements based on user choices and service contexts. Users can start with simplified device-based verification for immediate access, then dynamically transition to more comprehensive user-based verification when they choose to register personal information or when specific services require enhanced verification.
Solution Approach 2:
The system is designed to support multiple identification methods universally. Both first identification information (device-based) and second identification information (user-based) can be used interchangeably for electronic value management, allowing the system to serve diverse user needs and service types without mandating a single approach.
3Adaptability or versatility
If the system supports both device-based and user-based identification, then system flexibility and user choice are improved, but system complexity and management overhead are deteriorated
Solution Approach 1:
The system extracts and separates the core electronic value management function from the personal information registration requirement. By taking out the registration step as optional rather than mandatory, the system maintains flexibility to support both device-based and user-based identification while reducing overall complexity for users who only need basic functionality.

AI summary
In a network system where a balance of virtual currency is recorded in data D41 of balance information in association with a user ID unique for each user, the user ID being associated with personal information of the user; and addition or subtraction is performed with respect to the amount of virtual currency in response to a purchase requirement or a consumption requirement designating the user ID or a card ID linked with the user ID, in a case where use of virtual currency is required with designating the card ID, it is determined whether the user ID linked with the card ID exists (S103), and when it is determined the user ID linked with the card ID does not exist, a user ID which is not associated is generated (S131), and the provisional user ID and the card ID are linked with each other (S132).
