Vehicle Locking System with Biometric Verification for Private Space Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle locking systems for private spaces like trunks and glove compartments are cumbersome to manage, especially when temporary third-party access is required, as they often require carrying a sub-key or using the main key, which compromises security and convenience.
Innovation Solution
A locking system incorporating a communication unit, smart key with unique information, mobile device with unique information, biometric information acquisition units, and verification units that wirelessly connect and verify information to control locking and unlocking of private spaces, ensuring only registered individuals can access these areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a main key is given to a third party agent for temporary tasks, then the agent can access the vehicle, but private spaces become vulnerable to unauthorized access
Solution Approach 1:
The system divides key functions into two separate keys: a main key with full vehicle access and a sub key with limited access to only driving functions. This segmentation allows the main key to be given to agents for temporary tasks while the sub key retains full security capabilities for the owner, resolving the contradiction between convenience and security.
Solution Approach 2:
The sub key is designed with differentiated access rights - it can unlock the vehicle doors for driving purposes but cannot access private spaces like the trunk or glove compartment. This local quality approach grants appropriate permissions for temporary agents while maintaining security for sensitive areas.
2Reliability
If a sub key is carried for secure access control, then private spaces remain secure, but user convenience deteriorates due to the burden of carrying multiple keys
Solution Approach 1:
The system merges the functionality of multiple keys into a single smart key unit that contains both main key and sub key capabilities. The biometric authentication system further consolidates security verification into one integrated process, eliminating the need for users to physically carry and manage separate keys while maintaining security levels.
Solution Approach 2:
The system replaces the mechanical key system with a biometric authentication system using fingerprint recognition. This substitution eliminates the need for physical key cards or fobs, providing contactless authentication that maintains security while significantly improving convenience and eliminating the burden of carrying multiple keys.
3Reliability
If biometric verification is implemented for all access, then security is improved, but system complexity increases
Solution Approach 1:
The system implements biometric verification selectively rather than universally - it is applied only when a sub key is detected or when access to private spaces is attempted. For main key operations, traditional authentication methods suffice. This partial application of biometric verification maintains high security where needed while avoiding unnecessary complexity in routine operations.

AI summary
A locking system includes a communication unit, a key including a first unique information, the key being capable of wirelessly connecting to the communication unit, a mobile device including a second unique information, the mobile device being capable of wirelessly connecting to the communication unit, a first verification unit that verifies the first unique information, a locking device configured to lock and unlock the space, a locking device controller that controls the locking device, a biometric information acquisition unit that acquires biometric information capable of identifying an individual, and a second verification unit that verifies the second unique information and the biometric information. After the first unique information and the second unique information are verified, the biometric information is verified, the space is unlocked when the acquired biometric information matches, and the space is locked or maintained in a locked state when the acquired biometric information does not match.
