Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated image capture and analysis is used to verify identification documents, then verification speed and productivity are improved, but measurement precision and reliability of verification may deteriorate due to inability to perform manual checks
Solution Approach 1:
The verification process is divided into multiple independent analysis modules that each examine specific aspects of the identification document and user. These include facial recognition, document authenticity verification, liveness detection, and behavior analysis. Each module operates independently and contributes to the overall verification decision, allowing parallel processing while maintaining comprehensive verification coverage.
Solution Approach 2:
The system dynamically adjusts verification parameters based on risk assessment and document type. Different verification strictness levels are applied depending on the transaction amount, user profile, and detected anomalies. The system can increase scrutiny on specific parameters (such as requiring additional liveness checks) when risk indicators are detected, thereby maintaining reliability while preserving overall efficiency.
2Reliability
If manual verification by human operators is used, then reliability of verification is improved through direct observation, but device complexity and operational cost increase
Solution Approach 1:
The system replaces manual mechanical verification processes with automated computational analysis. Instead of human operators physically examining documents and conducting video calls, the system uses image processing algorithms, machine learning models, and automated document validation to perform verification tasks. This substitution maintains verification quality while eliminating the complexity of human operator management.
Solution Approach 2:
An automated verification system acts as an intermediary between the user and the verification process. The system includes intermediate components such as image processing modules, liveness detection algorithms, and risk assessment systems that facilitate verification without requiring direct human intervention. These intermediary components handle the complexity of verification while presenting a simple interface to users.
3Measurement precision
If multiple images are captured from different angles to verify security features, then measurement precision of security feature detection is improved, but use of energy and time for verification increase
Solution Approach 1:
The system captures multiple images from different angles only when necessary, based on risk assessment and document type. For low-risk transactions or standard documents, the system may use fewer images or alternative verification methods. For high-risk transactions or documents with complex security features, the system increases the number of captured images and analysis depth. This selective approach maintains precision when needed while reducing overall energy consumption.
Solution Approach 2:
The system uses feedback from preliminary image analysis to determine whether additional images from different angles are necessary. After initial processing, the system assesses the quality and sufficiency of the captured images. If the preliminary analysis indicates adequate information is available, the system proceeds with verification without requiring additional images, thereby reducing energy consumption. When deficiencies are detected, the system requests supplementary images only when necessary.
Data Source
AI summary
A system for remote identification of users. The system uses deep learning techniques for authenticating a user from an identification document and using automated verification of identification documents. Identification documents may be authenticated by validating security features. The system may determine features expected in a valid identification document and determine whether those features are present, employing techniques, such as determining whether direction-sensitive features are present. Liveness of a user indicated by the identification document may be determined with a deep learning model trained for identification of facial spoofing attacks.
