Solution Overview

Problem

Existing identity verification methods, such as biometric and verification code verification, are costly and pose privacy concerns, especially in high-security applications like payment apps, and are vulnerable to hacking, leading to user resistance and potential privacy breaches.

Innovation Solution

An identity verification method that determines whether a terminal device is a commonly used device by comparing its hardware model parameters with device model distribution information, allowing the system to skip verification for trusted devices and perform verification only when necessary to ensure security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If biometric identity verification is used to ensure security, then security is improved, but user privacy concerns increase and verification costs rise

Engineering Contradiction:
ImprovesecurityVSAvoidprivacy concerns
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The verification system is segmented into two independent parts: device identity verification (using hardware parameters) and user identity verification (using biometric or verification code). The server first verifies the device, and only if the device is trusted does it proceed to user verification. This segmentation allows the system to maintain security while reducing privacy concerns by minimizing unnecessary biometric verification.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The server performs preliminary device verification by comparing hardware parameters before triggering user identity verification. This preliminary action filters out untrusted devices early, preventing unnecessary biometric verification and reducing both privacy concerns and verification costs for legitimate users.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If verification code identity verification is used to ensure security, then security is improved, but verification costs increase due to SMS expenses

Engineering Contradiction:
ImprovesecurityVSAvoidverification costs
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The server performs preliminary device verification by comparing hardware parameters before triggering verification code sending. This preliminary action filters out untrusted devices early, preventing unnecessary SMS verification and reducing verification costs for legitimate users while maintaining security.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system applies verification selectively rather than universally. Only untrusted devices or high-risk operations trigger verification code sending, while trusted devices enjoy streamlined verification. This partial action approach reduces overall verification costs while maintaining adequate security.

Inventive Principle:
Principle #16Partial or excessive action

3Reliability

If frequent identity verification is performed to ensure security, then security is improved, but user convenience deteriorates and verification frequency increases

Engineering Contradiction:
ImprovesecurityVSAvoiduser convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The verification process is segmented into device verification and user verification stages. Device verification using hardware parameters is performed first and can be cached for multiple subsequent operations. This segmentation reduces the frequency of full identity verification, improving user convenience while maintaining security through the initial device trust assessment.

Inventive Principle:
Principle #1Segmentation

4Measurement precision

If device model distribution information is collected and analyzed, then verification accuracy is improved, but system complexity increases

Engineering Contradiction:
Improveverification accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The server performs multiple functions using the collected device model distribution information: it identifies commonly used devices, detects abnormal devices, and makes verification decisions. This multi-functionality justifies the data collection and processing complexity by providing comprehensive security and verification optimization.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

This specification provides an identity verification method and device, and a storage medium. In the method, in response to an identity verification request sent by a terminal device, a verification device obtains a target account of an application corresponding to the identity verification request, a first hardware parameter of the terminal device, and a second hardware parameter corresponding to the target account; and obtains a distribution status of each device model in a device that uses the application; and then the verification device can determine, based on the obtained parameter and distribution status, whether the terminal device is a commonly used device corresponding to the target account; and then indicate, based on a determining result, the terminal device to or not to initiate an identity verification procedure for a user.
