Digital Currency Sub-Wallet Tokenization for User-Controlled Payment Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing electronic payment systems, users cannot actively manage payment tokens, leading to limitations in asset management and security, as payment tokens are generated and managed centrally without user control.
Innovation Solution
A payment tokenization method and system based on a digital currency sub-wallet, allowing users to parse and manage payment token acquisition requests, verify wallet passwords, generate digital currency sub-wallets, and create payment tokens, enabling users to select merchants and manage token limits, thereby enhancing user control and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If payment tokens are generated and managed centrally without user control, then system simplicity is maintained, but user control and security are reduced
Solution Approach 1:
The patent segments the payment token management system into multiple components: user terminal for initiating requests, wallet system for generating sub-wallets, and token service provider for creating payment tokens. This segmentation distributes control across different entities, enabling user control while maintaining system manageability through clear separation of responsibilities.
Solution Approach 2:
The patent introduces intermediary components including the wallet system that acts as a mediator between the user terminal and token service provider, and the use of payment tokens as intermediaries between actual payment accounts and merchants. These intermediaries enable user control over payment processes while maintaining system simplicity through standardized interaction protocols.
2Reliability
If users can actively manage payment tokens, then security and convenience are improved, but system complexity increases
Solution Approach 1:
The patent implements preliminary action by requiring users to bind payment accounts and generate digital wallet addresses before actual payments. The wallet system pre-generates sub-wallets and users can pre-configure payment preferences and limits. This preliminary setup enhances security by establishing controlled pathways before transactions occur, while the automated nature of these preliminary actions prevents excessive complexity.
Solution Approach 2:
The patent enables self-service functionality where users can independently bind their own payment accounts, generate digital wallet addresses, and manage their payment tokens without requiring manual intervention from the system operator. This self-service approach improves security through user autonomy while the standardized interfaces and automated processes prevent the system from becoming overly complex.
3Reliability
If payment tokens are defined for particular merchants and channels, then transaction security is improved, but flexibility in asset management is reduced
Solution Approach 1:
The patent implements dynamics by allowing the payment token system to adapt to different scenarios. Users can dynamically bind different payment accounts for different purposes, generate multiple digital wallet addresses, and create payment tokens with varying permissions for different merchants and channels. This dynamic configuration enables both transaction security through specific bindings and asset management flexibility through multiple configurable options.
Solution Approach 2:
The patent utilizes parameter changes by allowing different configurations of payment tokens based on various parameters such as merchant ID, channel type, payment account, and limit settings. The system can adjust token parameters to match different transaction requirements, enabling secure transactions for particular merchants while maintaining overall asset management flexibility through parameterized token generation.

AI summary
Provided are a payment tokenization method, apparatus and system based on a digital currency sub-wallet. One specific embodiment of the method includes: parsing a payment token acquisition request of a user, so as to obtain a target digital wallet, a target merchant, and a wallet payment password corresponding to the target digital wallet; sending the wallet payment password to an operating system of the target digital wallet, so that the operating system of the target digital wallet verifies the wallet payment password; in the case that the verification is passed, sending a sub-wallet opening request to the operating system of the target digital wallet; and in the case that wallet opening is successful, sending a payment token generation request to a token service provider, so that the token service provider generates a payment token corresponding to a digital currency sub-wallet.
