Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing network security systems are used, then network service provision is maintained, but fraudulent data usage cannot be effectively detected
Solution Approach 1:
The detection system is divided into multiple independent analysis modules: device identifier analysis module, registration analysis module, traffic analysis module, and examination analysis module. Each module focuses on specific aspects of fraud detection, allowing for specialized processing and more accurate detection without requiring a complete system redesign.
Solution Approach 2:
The network device performs multiple functions: it monitors network traffic, analyzes device identifiers, examines registration patterns, profiles applications, and generates fraud scores all within a single system. This multi-functional approach enables comprehensive fraud detection while maintaining system efficiency and avoiding the need for multiple separate systems.
2Loss of energy
If network restrictions are imposed to prevent fraud, then revenue protection is improved, but legitimate user experience deteriorates
Solution Approach 1:
The system continuously monitors network traffic and device behavior, generating fraud scores based on analyzed patterns. This feedback mechanism allows the system to dynamically adjust monitoring and detection efforts, taking action only when fraud is detected with sufficient certainty, thereby protecting revenue while minimizing impact on legitimate users.
Solution Approach 2:
The system changes the parameters of monitoring and detection based on detected patterns. By adjusting detection sensitivity and monitoring intensity according to specific traffic patterns and fraud indicators, the system can protect revenue through targeted interventions rather than blanket restrictions, preserving legitimate user experience.
3Measurement precision
If comprehensive fraud detection analysis is performed, then detection certainty is improved, but system complexity increases
Solution Approach 1:
The comprehensive analysis is segmented into distinct functional modules: device identifier analysis, registration analysis, traffic analysis, and examination analysis. Each module handles specific aspects of fraud detection independently, making the overall complex system manageable through modular design and enabling parallel processing.
Solution Approach 2:
The network device acts as an intermediary that collects data from multiple sources (network traffic, device identifiers, registration information) and processes it through various analysis modules before generating a final fraud score. This intermediary role allows comprehensive analysis to be performed in a structured, manageable way that balances detection certainty with system complexity.
