Mobile Payment Account Unlocking via Passcode Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data security methods for financial transactions are inadequate in preventing fraudulent activities, as they can be compromised by unauthorized access, leading to financial losses and resource inefficiencies for consumers, merchants, and financial institutions.
Innovation Solution
A system and method that allows a financial account to be unlocked for a limited period and amount, requiring user authentication via a passcode, to facilitate secure financial transactions, thereby reducing fraudulent activities and enhancing account security through a mobile payment application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional data security methods are used for financial transactions, then account access is maintained, but fraudulent activities can still occur leading to financial losses
Solution Approach 1:
The account access is segmented into multiple components: account number, passcode, and unlock amount. Each component serves as a separate security layer that must be satisfied individually. The passcode verifies user identity while the unlock amount limits the financial exposure, creating a segmented security model that prevents fraud even if one layer is compromised.
Solution Approach 2:
The system performs preliminary authentication actions before allowing any financial transaction. The user must first provide the correct passcode and specify an unlock amount before the account is unlocked for transactions. This preliminary verification ensures that only authorized users can access funds and prevents unauthorized transactions from occurring in the first place.
2Reliability
If account access is restricted to prevent fraud, then security is improved, but user convenience is reduced
Solution Approach 1:
The account access state is dynamic rather than static. The account transitions between locked and unlocked states based on user authentication and transaction requirements. When a user provides the correct passcode and specifies an unlock amount, the account dynamically unlocks for that specific transaction. After the transaction completes or the time expires, the account automatically returns to locked state, creating a flexible security model that balances protection with convenience.
Solution Approach 2:
The security restrictions are applied locally to specific transactions rather than globally to all account access. Each transaction can have its own unlock amount and time parameters. This allows the system to provide strong security for high-value transactions while allowing easier access for low-value transactions, tailoring the security level to the specific local requirements of each transaction type.
3Ease of operation
If unlimited access is provided to users, then ease of operation is improved, but fraudulent transactions increase
Solution Approach 1:
The system applies partial restrictions rather than complete blocking. Instead of denying all access, the system allows access up to a specified unlock amount and for a limited time period. This partial action approach enables legitimate users to access their accounts for reasonable transactions while automatically blocking excessive or fraudulent transactions that exceed the predefined limits, achieving a balance between accessibility and fraud prevention.
Solution Approach 2:
The system provides feedback to users about their account status and transaction limits. When a user attempts a transaction, the system verifies the passcode and checks whether the requested amount is within the unlock limit. If the transaction exceeds the limit or the time expires, the system provides feedback by rejecting the transaction. This feedback mechanism helps users understand the security constraints and adjust their behavior accordingly, reducing fraudulent attempts while maintaining legitimate access.

AI summary
Embodiments of the invention provide systems and methods to unlock an account associated with a user for a limited period of time to enable the user conduct a transaction using funds from that account. In one embodiment of the invention, the user may select options relating to the transaction using a payment menu provided at a mobile communications device associated with the user. A notification message is received at the mobile communications device informing the user that the account is unlocked for a certain period of time and for a certain amount. After the transaction is complete, the user is notified and the account is locked again.
