Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biometric identification technologies, such as face, fingerprint, voiceprint, and iris identification, face challenges in security and convenience due to environmental factors, forgery, accuracy issues, and limited usability, particularly for elderly and children.
Innovation Solution
An unlocking method and intelligent lock utilizing vein input and identification, involving the collection and comparison of vein images to determine unlocking states, with features like positional adjustment, image processing, and feature map construction to enhance security and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If face identification is used, then the authentication process is simple, but it is easily affected by external environments and lacks sufficient security
Solution Approach 1:
The patent combines multiple biometric identification methods (face, fingerprint, iris, voiceprint) into a unified authentication system. The controller integrates results from multiple identification modules to make authentication decisions, thereby maintaining operational simplicity while significantly enhancing security through multi-factor verification
2Ease of operation
If fingerprint identification is used, then the authentication process is convenient, but it is easily forged and copied, and affected by skin surface conditions
Solution Approach 1:
The system integrates fingerprint identification with other biometric methods (face, iris, voiceprint) in a multi-modal authentication framework. The controller cross-validates fingerprint results with other identification outcomes, maintaining convenience while preventing forgery through redundant verification channels
Solution Approach 2:
The controller acts as an intermediary that processes and cross-validates fingerprint identification results with other biometric data. This intermediary layer adds a verification step that prevents direct use of potentially forged fingerprints while maintaining the convenience of fingerprint-based authentication
3Ease of operation
If voiceprint identification is used, then the authentication process is simple, but it has low accuracy and is vulnerable to sound recording and wiretapping
Solution Approach 1:
The patent integrates voiceprint identification with multiple other biometric methods in a unified authentication system. The controller combines voiceprint results with face, fingerprint, and iris identification outcomes, maintaining the simplicity of voice-based authentication while achieving high accuracy through multi-factor verification that prevents reliance on potentially recorded voice data

AI summary
An unlocking method and an intelligent lock based on vein input and identification. The method includes steps of obtaining positional information of a target part, adjusting a position of the target part to be within a preset position-identification range, inputting a vein image of the target part to be within the position-identification range, where the vein image includes a first vein image and a second vein image; processing the input first vein image to obtain a first vein feature of the first vein image, constructing a feature map based on the first vein feature; processing the input second vein image to obtain a second vein feature of the second vein image, comparing the second vein feature with the first vein feature of the feature map to obtain a comparison result, and determining an unlocking state based on the comparison result.
