Mobile Tokenization Hub for Unified Payment Identity Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing payment systems fail to efficiently manage and standardize tokens across various mobile devices and payment infrastructure, leading to security and compliance issues due to differences in device types and infrastructure requirements.
Innovation Solution
A mobile tokenization hub with a common tokenization capability module that receives token requests, identifies device information, determines token types, and provides tokens to mobile devices, while also handling dynamic identification information and token lifecycle management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different types of tokens are used for different mobile devices and payment channels, then device compatibility and payment channel support are improved, but system complexity and token management difficulty increase
Solution Approach 1:
A centralized token service is introduced as an intermediary between mobile devices and payment channels. This service receives token requests from various devices, determines the appropriate token type based on device information, and returns the corresponding token. This mediator abstracts the complexity of managing multiple token types away from individual devices and payment channels, allowing them to work together without direct complexity exposure.
Solution Approach 2:
The token service is designed as a universal system that can handle multiple types of mobile devices (smartphones, tablets, wearables) and various payment channels (contactless, online, in-app). A single token service implementation supports all these different scenarios by dynamically determining the appropriate token type, eliminating the need for separate token management systems for each device or channel.
2Reliability
If tokens are used to substitute sensitive data, then security is improved and PCI compliance burden is reduced, but token management and lifecycle handling complexity increase
Solution Approach 1:
The token service operates autonomously to manage the entire token lifecycle. When a token request is received, the service automatically determines the appropriate token type based on device information, generates or retrieves the suitable token, and returns it to the requesting device. This self-service approach eliminates the need for manual token management intervention, reducing operational complexity despite the sophisticated tokenization process.
Solution Approach 2:
The complexity of token management is extracted from the mobile devices and payment processing systems and centralized in the dedicated token service. Individual devices and payment channels only need to interact with the token service through simple request-response interfaces, while the complex logic of token type determination, generation, and lifecycle management is isolated within the token service itself.
3Reliability
If device information is analyzed to determine token type, then token appropriateness and security are improved, but processing time and computational requirements increase
Solution Approach 1:
Device information is collected and analyzed as part of the initial token request process, before the actual token generation or retrieval occurs. By determining the appropriate token type early in the request flow based on pre-analyzed device characteristics, the system avoids unnecessary processing steps and ensures the correct token is provided from the start, minimizing overall processing time.
