Security Display Control for Transaction Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminal devices, such as computers and smartphones, are vulnerable to Trojans that can tamper with transaction information, leading to illegal transactions and user losses, as users cannot reliably confirm the accuracy of displayed information.
Innovation Solution
A security display method and device that enters a security display control state, filters information based on a specified identifier, and securely processes and displays security processing information at a preset fixed address, ensuring the integrity and security of displayed data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device displays transaction information directly without security verification, then the display operation is simple and fast, but the transaction information may be tampered by Trojans leading to illegal transactions
Solution Approach 1:
The display control is segmented into multiple independent verification modules: a display information acquisition module that获取s information to be displayed, a security verification module that checks for specified identifiers, and a display control module that determines the display method based on verification results. This segmentation allows security verification to be integrated without overwhelming system complexity.
Solution Approach 2:
The patent implements preliminary security verification before display by checking whether the information to be displayed contains a specified identifier. This preliminary action identifies potentially tampered information in advance, allowing the system to take appropriate security measures (such as displaying security prompts or blocking display) before the user sees the information, thus preventing illegal transactions.
2Reliability
If the terminal device implements security verification by filtering information based on specified identifiers, then the transaction security is improved, but the information processing time and computational resources increase
Solution Approach 1:
The patent applies partial verification by checking only for the presence of a specified identifier in the information to be displayed, rather than performing comprehensive content analysis. This partial action approach provides sufficient security verification (identifying tampered information) while minimizing processing time and computational overhead, avoiding excessive verification that would slow down normal operations.
3Ease of operation
If the terminal device displays security processing information at a fixed security display address, then the user can easily locate security information, but the display flexibility is reduced
Solution Approach 1:
The patent implements local quality by designating a specific fixed display address (such as a corner or specific region) for security-related information while allowing other non-security information to be displayed flexibly in remaining areas. This creates different display qualities for different types of information: security information has a fixed, easily locatable position, while general information maintains display flexibility, thus resolving the contradiction between ease of identification and layout adaptability.
Data Source
AI summary
The present disclosure provides a security display method, a security display device, and a security terminal. The security display method includes the following. In a security display control state, first information to be displayed currently is obtained. It is determined whether the first information to be displayed includes a specified identifier. In response to the first information to be displayed includes the specified identifier, the security processing information is obtained by filtering the first information to be displayed based on the specified identifier, and the security processing information is securely processed. The security processing information is displayed at a security display address. The security display address is a preset fixed display address. Or, a security identifier is added to the security processing information to obtain security display information and the security display information is displayed.
