Token Domain Control via Segmented Value Token and Code
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current token systems face challenges such as insufficient unique token values, especially when multiple tokens are issued for a single user account, and difficulties in tracking user activity as tokens replace primary account numbers.
Innovation Solution
The method involves issuing a single value token for use across multiple domains, accompanied by a unique token code for each domain, ensuring the token's validity and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple unique tokens are issued for each domain, then token validity and security are improved, but the quantity of unique token values is exhausted
Solution Approach 1:
The token is segmented into two parts: a value token that remains constant across domains, and a domain-specific token code that varies by domain. This segmentation allows the same value token to be used across multiple domains without exhausting unique token values, as each domain combines the value token with its specific token code to create a unique token identifier.
Solution Approach 2:
The value token is designed to be universal and can be used across multiple different domains. Instead of creating a new unique token for each domain, the system allows one value token to serve multiple domains when combined with domain-specific token codes, thereby reducing the total number of unique token values needed while maintaining security and validity.
2Reliability
If tokens replace primary account numbers, then security is improved, but user activity tracking becomes difficult
Solution Approach 1:
The token code acts as an intermediary that links the value token to a specific domain. When a transaction occurs, the system can use the value token combined with the domain identifier to track user activity across different domains while maintaining security. The token code ensures that the value token is properly associated with the correct domain for tracking purposes.
3Quantity of substance
If a single value token is used across multiple domains, then token value exhaustion is prevented, but domain-specific validation complexity increases
Solution Approach 1:
By segmenting the token into a value token and a domain-specific token code, the validation process becomes more structured. The value token validation can be centralized and simplified, while domain-specific validation is handled through the token code association. This segmentation reduces overall validation complexity compared to managing entirely unique tokens for each domain.
Data Source
AI summary
A method for providing a token code in conjunction with a value token is disclosed. The token code serves as a shared secret for authenticating the use of the value token. Multiple token holders can possess the same value token, but each token holder may have a different token code for use with the value token.
