Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different device providers use their own human biological characteristic collection algorithms, then each device can achieve accurate authentication with its own registered data, but devices from different providers become incompatible and users must register separately on each device
Solution Approach 1:
The patent applies universality by enabling the authentication system to work across multiple device providers. The verification device receives characteristic codes from different terminal devices and uses a unified verification algorithm to authenticate users, making the system compatible with devices from various providers while maintaining authentication accuracy.
Solution Approach 2:
The patent changes the parameter of the verification algorithm to adapt to different collection algorithms. By adjusting the verification process to accommodate characteristic codes generated by different device types, the system maintains reliability across diverse devices without requiring users to register separately on each device.
2Adaptability or versatility
If users register on multiple terminal devices to ensure compatibility, then authentication can be performed across different devices, but the operating procedures become complicated and convenience is reduced
Solution Approach 1:
The terminal device automatically includes device type information with the authentication request, and the verification device automatically selects the appropriate verification algorithm based on this information. This self-service mechanism eliminates the need for users to manually configure or register on multiple devices, simplifying the operation while maintaining cross-device compatibility.
3Adaptability or versatility
If a unified algorithm is used across all devices, then compatibility is improved and users can authenticate on any device, but device-specific optimization may be lost
Solution Approach 1:
The patent applies parameter changes by dynamically selecting different verification algorithms based on the device type. The verification device receives device type information and adjusts the verification parameters accordingly, allowing each device type to use its optimized algorithm while maintaining a unified system architecture that ensures compatibility across all devices.

AI summary
A human biological characteristic file corresponding to a particular identity is received and used as a base file. A characteristic code to be authenticated is obtained according to a human biological characteristic of a person who requests identity authentication when an identity authentication request corresponding to the particular identity is received. A base characteristic code is collected from a base file. A collecting algorithm applied for collecting the base characteristic code is the same as or matches an algorithm applied for obtaining the characteristic code. The present techniques determine whether the base characteristic code and the characteristic code correspond to a same human biological characteristic. If a result is positive, the identity authentication request is verified. The present techniques implement communication between different terminal devices of different manufacturers and effectively improve user experiences, thereby efficiently and conveniently implementing remote identity authentication.
