Token Management System for Multi-Tenant Digital Wallets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital wallet applications face inefficiencies in storing and managing large numbers of tokens for multiple funding accounts, leading to burdensome computing resource usage on mobile devices.
Innovation Solution
Implementing a token management system that shares tokens among related funding accounts, modifies token characteristics, and dynamically allocates restrictions based on transaction history to optimize resource usage and enhance security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If one-time use tokens are generated for each funding account to avoid transmitting sensitive data, then security is improved, but the number of tokens to be stored and managed increases significantly
Solution Approach 1:
The patent merges token management across multiple funding accounts by allowing a single token to be associated with multiple funding accounts. Instead of generating separate tokens for each account, the system combines token usage rights so that one token can securely access multiple funded accounts, thereby reducing the total number of tokens while maintaining security.
Solution Approach 2:
The patent implements multi-functionality by designing tokens that can serve multiple funding accounts simultaneously. A single token is made universal across different funding accounts, allowing it to function as a secure access key for multiple accounts rather than being restricted to a single account, thus reducing token quantity while preserving security.
2Adaptability or versatility
If tokens are stored for each funding account to enable electronic transactions, then transaction capability is improved, but computing resource usage on mobile devices increases
Solution Approach 1:
The system merges the storage and management of tokens by allowing one token to represent multiple funding accounts. This consolidation reduces the computational burden on mobile devices by decreasing the number of tokens that need to be stored, managed, and processed, while still enabling transactions across multiple funded accounts.
Solution Approach 2:
By making tokens universal across multiple funding accounts, the system reduces the total token count that mobile devices must handle. This multi-functional token design decreases memory usage and computational resources required for token management, while maintaining full transaction capability across all funded accounts.
3Reliability
If multiple tokens are generated for each funding account to ensure sufficient tokens are available, then token availability is improved, but the burden of storing and managing tokens increases
Solution Approach 1:
The patent combines token management across funding accounts by enabling a single token to serve multiple accounts. This approach ensures token availability for transactions while simplifying the management complexity by reducing the total number of tokens that need to be tracked, stored, and renewed across the system.
Solution Approach 2:
By creating universal tokens that work across multiple funding accounts, the system maintains adequate token availability without proportionally increasing management complexity. Each token becomes multi-functional, reducing the overall token count and thereby lowering the complexity of storage, tracking, and management operations.

AI summary
Methods and systems are presented for facilitating sharing of tokens among different funding accounts linked to a digital wallet application to improve the computer resource efficiency of the mobile device. When a first funding account is linked to the digital wallet application is received, a token management system may determine whether a set of tokens have already been issued and stored on the mobile device for another related funding account. The token management system may cause a token service provider server to abort generating additional tokens for the first funding account. Instead, the token management system may modify characteristics of one or more of the set of tokens existed on the mobile device, to enable the one or more existing tokens to be usable in electronic payment transactions in association with the first funding account or the second funding account.
