Intelligent Lock Combining Identity and Password Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional safe deposit boxes are vulnerable to password cracking due to ease of guessing or rapid testing, leading to a high risk of theft, as they rely solely on password input or identity recognition without adequate security measures.
Innovation Solution
An intelligent lock system that combines a mechanical lock with an identity recognition module and a password input module, using a controller to verify both identity and password, and optionally sets a random password if the user is not legitimate, enhancing security by requiring both valid identity and password for unlocking, and providing alerts for unauthorized attempts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If only password input or identity recognition is used for unlocking, then the ease of operation is improved, but the security is worsened due to vulnerability to password cracking
Solution Approach 1:
The patent combines multiple authentication methods (identity recognition module and password input module) into a unified unlocking system. The controller integrates both authentication streams and requires both to succeed for unlocking, creating a merged security mechanism that maintains ease of operation while significantly improving security against password cracking attempts
Solution Approach 2:
The unlocking authentication is segmented into two independent components: identity recognition authentication and password authentication. The controller processes these separately and requires both to be successful, dividing the authentication process into distinct segments that must both be satisfied, thereby preventing single-point failure modes
2Reliability
If the reference unlocking password is changed to a random password when unauthorized access is detected, then the security is improved, but the ease of operation is worsened for legitimate users
Solution Approach 1:
The reference unlocking password is made dynamic rather than static. When the controller detects unauthorized access attempts (when legitimate user is not confirmed), it automatically changes the password to a random value. This dynamic adjustment of password based on security conditions improves security against unauthorized access while maintaining ease of operation for legitimate users who undergo proper identity verification
Solution Approach 2:
The password parameter is changed from a fixed state to a variable state based on authentication outcomes. The controller modifies the password parameter (setting it to random) when detection of unauthorized access occurs, and restores it when legitimate user authentication is confirmed, using parameter changes to balance security and operability

AI summary
The present disclosure provides an intelligent lock, a method for operating the same, and an intelligent safe deposit box. The intelligent lock comprises: a mechanical lock body; an identity recognition module configured to acquire identity information of a user; a password input module configured to acquire a password input by the user; a controller electrically connected to the identity recognition module and the password input module, and configured to: determine whether the user is a legitimate user according to the identity information, determine whether the password is consistent with a reference unlocking password, and control a state of the mechanical lock body, wherein the controller controls the mechanical lock body to be in an unlocked state only on condition that it is determined that the user is a legitimate user and the password is consistent with the reference unlocking password.
