Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing information display methods rely heavily on visual inspection for recognizing secure information, making it difficult for users to accurately determine the security of transmitted information, as special identifications can be easily imitated.

Innovation Solution

The method involves parsing received information containing a 2D code with anti-fake information, detecting whether the information is transmitted by a security server, and displaying corresponding content only if verified secure, using a terminal and security server system that generates and verifies anti-fake information within the 2D code.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If visual inspection of special identification is used to recognize secure information, then the user can easily identify secure information with naked eyes, but the special identification can be easily imitated making it difficult to accurately recognize security

Engineering Contradiction:

Improveease of identifying secure informationVSAvoidaccuracy of security recognition

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces the mechanical visual inspection system with an automated terminal-based verification system. The terminal automatically parses 2D codes, extracts anti-fake information, detects security server transmission, and displays content only when verified secure. This substitution eliminates reliance on human visual recognition while maintaining ease of use through automatic operation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an intermediary verification mechanism between the user and the information. The terminal acts as an intermediary that automatically verifies security through 2D code parsing and anti-fake information detection, preventing direct exposure to potentially fake identifications and ensuring accurate security recognition.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If automatic recognition through 2D code parsing and anti-fake information detection is implemented, then the accuracy of security recognition is improved, but the device complexity increases

Engineering Contradiction:

Improveaccuracy of security recognitionVSAvoidcomplexity of terminal and security server system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the security verification system into distinct functional modules: 2D code parsing module, anti-fake information extraction module, security server detection module, and content display control module. This segmentation allows each module to perform a specific function independently, making the overall complex system more manageable and maintainable while achieving high accuracy in security recognition.

AI summary

Disclosed is an information display method, a terminal, a security server and a system, which belong to the field of computers. The method comprises: parsing received information which includes corresponding two-dimensional (2D) code carrying content data, the content data containing anti-fake information; acquiring the content data carried in the 2D code, and detecting whether the information is transmitted by a security server according to the anti-fake information contained in the content data; and acquiring content to be displayed corresponding to the information from the security server and displaying the content to be displayed if the information is detected as being transmitted by the security server.
