Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If professional authorization machines are used for identity verification, then document forgery and re-make issues are addressed, but device complexity and operational convenience deteriorate
Solution Approach 1:
The patent uses image copying technology to capture identity document images and creates digital replicas for verification. The system processes these image copies through multiple verification layers (watermark detection, anti-counterfeiting code recognition, document structure analysis) to detect forgery without requiring physical contact with the original document, thus eliminating the need for complex professional authorization machines while maintaining verification reliability
Solution Approach 2:
The patent replaces mechanical/physical verification systems (professional authorization machines that require physical document handling) with electronic/image-based verification systems. By substituting mechanical document inspection with digital image analysis algorithms, the system achieves comparable or superior verification capability while dramatically reducing device complexity and enabling remote online verification
2Reliability
If professional authorization machines are used for identity verification, then security level is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements self-service verification where the system automatically performs multiple verification tasks (image quality assessment, watermark detection, anti-counterfeiting code recognition, document-identity matching) without requiring manual intervention. Users simply submit identity document images through the system, which then autonomously completes the entire verification process, dramatically improving ease of operation while maintaining high security standards
Solution Approach 2:
The patent performs preliminary verification actions by pre-processing identity document images through multiple analysis layers before final verification. The system pre-detects watermarks, anti-counterfeiting codes, and document structure characteristics, and pre-compares them against stored templates and databases, enabling rapid and convenient final verification decisions without requiring users to manually perform complex verification steps
3Ease of operation
If online identity verification is implemented without professional machines, then operational convenience is improved, but measurement precision deteriorates
Solution Approach 1:
The patent segments the document verification process into multiple independent analysis layers: image quality assessment, watermark detection, anti-counterfeiting code recognition, document structure analysis, and identity-information verification. Each segment focuses on specific verification aspects with specialized algorithms, achieving high measurement precision for each aspect while maintaining overall system convenience for online operation
Solution Approach 2:
The patent applies multiple layers of verification analysis that go beyond traditional single-method verification. By performing excessive verification actions (detecting watermarks, anti-counterfeiting codes, document structure, and cross-validating with identity information) on the submitted images, the system achieves superior measurement precision for document authenticity detection while maintaining online operational convenience through automated processing

AI summary
Disclosed in the present application are a document verification and identity verification method and device. The method comprises: obtaining an image of an identity document of a to-be-verified object; verifying a source of the image of the identify document and/or an anti-counterfeiting identifier in the image of the identify document to obtain a first verification result; verifying authenticity of identity information in the image of the identify document to obtain a second verification result; and determining an identity verification result for the to-be-verified object based on the first verification result and the second verification result.
