Secure Module Token Management for Mobile Payment Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices lack a secure and efficient method for transmitting and managing payment information, particularly in mobile payment systems, which poses risks to data security and integrity.
Innovation Solution
An electronic device equipped with a secure module, multiple communication modules, and a processor that stores tokens and generates timestamps to create and transmit secure payment signals, ensuring high-security mobile payment transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional payment methods (cash or plastic card) are used, then payment simplicity is maintained, but security and efficiency in mobile transactions are insufficient
Solution Approach 1:
The patent extracts the sensitive payment information (card number, CVV, expiration date) from the main processor and stores it in a separate secure element. This isolation protects payment data from being accessed even if the main device is compromised, thereby improving payment security without significantly increasing overall system complexity.
Solution Approach 2:
The patent introduces a secure element as an intermediary between the payment application and the communication module. This intermediary securely stores payment tokens and manages the tokenization process, enabling secure mobile payments while keeping the main system architecture relatively simple.
2Reliability
If payment information is transmitted without tokenization, then transmission speed is faster, but data security and integrity are compromised
Solution Approach 1:
The patent creates a token that is a representative copy of the actual payment information. This token contains all necessary elements for transaction processing but cannot be reverse-engineered to reveal the original card details. The token can be transmitted quickly without compromising security, as it is just data without intrinsic value if intercepted.
Solution Approach 2:
The patent transforms sensitive payment parameters (card number, CVV, expiration date) into a different parameter format (token). This parameter transformation maintains the functional equivalence needed for transactions while eliminating the security risks associated with transmitting actual card information.
3Adaptability or versatility
If multiple communication modules are supported, then communication versatility is improved, but determining which module to use increases system complexity
Solution Approach 1:
The patent implements an automatic selection mechanism where the system itself determines which communication module to use based on pre-defined priorities and current conditions. The processor automatically selects the appropriate module (e.g., NFC for contactless payments, Bluetooth for peer-to-peer transactions) without requiring user intervention or complex manual configuration, thereby maintaining versatility while simplifying the user experience.
Data Source
AI summary
An electronic device and a method of payment are provided. The electronic device includes a secure module capable of storing at least one token, a first communication module, a second communication module, and at least one processor functionally or operatively connecting the secure module, the first and second communication modules to each other. The at least one processor is configured to control for determining at least one of the first and second communication modules as a communication module for performing a payment, and transmitting payment information containing a token related to the at least one of the first and second communication modules, from among the at least one token, to an external electronic device.
