Security Keyboard for Mobile Payment Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile payment security is compromised due to attacks from malicious software leading to the leak and loss of private user information and property, as existing technologies fail to adequately secure the information interaction process, particularly in verifying network access points and application signatures during transactions.
Innovation Solution
A method and device that monitor and verify the security of network access points and application signatures on mobile terminals, displaying a security keyboard for secure user input and transmitting data only when security parameters are met, ensuring secure information interaction by preventing malicious software interception and domain name hijacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mobile payment allows user information transmission, then payment convenience is improved, but security vulnerability to malicious software increases
Solution Approach 1:
A security application acts as an intermediary between the first application (payment app) and the user information transmission process. The security application monitors network access points, verifies application signatures, and controls the security keyboard to prevent malicious software from intercepting user information, thus resolving the contradiction between payment convenience and security vulnerability.
Solution Approach 2:
The system performs preliminary security verification by checking network access point security and application signature authenticity before allowing user information transmission. The security application pre-establishes security parameters and validates them in advance, preventing malicious interference during the actual payment process.
2Reliability
If security verification is performed on network access points and application signatures, then information security is improved, but system complexity increases
Solution Approach 1:
The security application performs multiple security functions including network access point verification, application signature validation, and secure keyboard control within a single unified system. This multi-functional approach improves information security while avoiding the complexity that would result from implementing separate verification systems for each function.
3Reliability
If a security keyboard from a second application is used, then user information protection is improved, but ease of operation decreases
Solution Approach 1:
The security application automatically manages the security keyboard, including its activation, deactivation, and switching between different applications. The system self-regulates the keyboard based on security parameter verification results, reducing the operational burden on users while maintaining strong information protection.
Data Source
AI summary
An electronic device with one or more processors, memory, and a display detects a user interaction with a user interface of a first application and, in response to detecting the user interaction with the user interface of the first application, determines whether one or more security parameters are satisfied, where a first security parameter is satisfied when a network access point being used by the electronic device satisfies predefined criteria. In accordance with a determination that the one or more security parameters are satisfied, the device: displays a security keyboard on the display corresponding to a second application different from the first application; and receives user information input via the security keyboard by a user of the electronic device. The device transmits the user information to a target terminal.
