Electronic Apparatus Lock State Authentication Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses face challenges in balancing user convenience and security, particularly with biometric authentication methods that are time-consuming and inconvenient, while traditional password or pattern inputs are easily compromised.
Innovation Solution
An electronic apparatus and method that switches to a lock release state upon successful input of user authentication information, with additional biometric authentication required only after a predetermined number of failed attempts, enhancing security by integrating fingerprint or iris recognition for re-authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric authentication (fingerprint, iris, voice, face) is used, then security is improved, but authentication process becomes time-consuming and inconvenient
Solution Approach 1:
The system dynamically adjusts the authentication method based on the device state. When the device is in lock state, simple authentication (password/pattern) is used for quick access. When in lock release state, biometric authentication is required for critical operations, creating a dynamic authentication framework that optimizes both speed and security based on contextual needs
2Productivity
If simple authentication (password, pattern) is used, then authentication speed is improved, but security is weakened as it can be easily solved by others
Solution Approach 1:
The authentication process is segmented into two distinct stages: initial authentication using simple methods (password/pattern) for speed, and subsequent re-authentication using biometric methods for security. This segmentation allows the system to benefit from both fast initial access and strong verification, with the second authentication stage acting as a security checkpoint after the device transitions to lock release state
3Reliability
If biometric authentication is required every time, then security is enhanced, but user convenience is reduced due to repeated authentication
Solution Approach 1:
Biometric authentication is performed periodically at specific intervals rather than continuously. The system requires biometric re-authentication after the device transitions from lock to lock release state, creating a periodic security checkpoint. This approach maintains security by verifying user identity at critical transition points while avoiding excessive authentication demands during normal usage

AI summary
An electronic apparatus for performing a user authentication is provided. The electronic apparatus includes an input and at least one processor configured to perform a user authentication based on user authentication information input through the input and user authentication information pre-stored in the electronic apparatus while the electronic apparatus is in a lock state, switch the electronic apparatus to be in a lock release state when the user authentication is successful, and enhance security for use of the electronic apparatus in the lock release state when the user authentication is successful based on the user authentication information input after a user authentication failure occurs from the input of the user authentication information input a predetermined number of times or more.
