Mobile Terminal Service Access via Local Bar Code Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile service access systems incur repeated communication network connection costs and have inadequate security, making them inefficient and vulnerable to fraud.
Innovation Solution
A method that allows users to access services through a software application on their mobile terminal, which generates an image containing a software application identifier and user personal identification code, enabling secure access without network connections, using encryption and a secure management entity to limit fraud.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user logs onto the server via communication network to obtain bar codes for services, then the user can access services, but repeated network connection costs are incurred
Solution Approach 1:
The system performs preliminary actions by pre-generating and storing bar codes in the mobile terminal's memory before the user needs to access services. The bar codes are created in advance and cached locally, eliminating the need for repeated network connections when the user wants to access different services. This preliminary preparation of service access credentials directly resolves the contradiction by maintaining service access capability while eliminating repeated connection costs.
2Ease of operation
If the system uses traditional bar code generation via server connection, then service access is enabled, but security level is inadequate for limiting fraud
Solution Approach 1:
The mobile terminal performs self-service by autonomously generating and managing bar codes using its own processing means and stored identification data, without requiring continuous server connection. The terminal uses its internal resources (processor, memory, identification data storage) to create and manage access credentials independently. This self-service approach enhances security by eliminating dependency on server-generated credentials while maintaining service access capability, directly addressing the fraud limitation issue.
3Loss of energy
If the mobile terminal stores identification data and generates bar codes locally, then network connection costs are eliminated, but device complexity increases
Solution Approach 1:
The mobile terminal's processing means and memory are designed with multi-functionality to handle both identification data storage and bar code generation operations. The same hardware resources (processor, memory) serve dual purposes: storing user identification data and generating service access bar codes. This universal use of existing components avoids adding separate dedicated hardware for bar code generation, thereby reducing overall device complexity while eliminating network connection costs.
4Adaptability or versatility
If the system requires repeated server connections for service access, then service updates can be obtained, but time consumption increases
Solution Approach 1:
The system performs preliminary action by pre-generating bar codes for services before the user needs to access them. The bar codes are stored in the mobile terminal's memory in advance, allowing the user to access services immediately without waiting for server connection and bar code generation. This preliminary preparation eliminates time consumption associated with repeated network connections while maintaining the ability to access various services, directly resolving the time loss contradiction.
