Blockchain Locking with Location Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking systems, including those for dwellings and automobiles, remain susceptible to unauthorized access despite increased security measures, necessitating a more secure and reliable access control method.
Innovation Solution
A blockchain-controlled and location-validated locking system that uses a processor to manage a lock's state, requiring a digital signature from authorized devices and proof of work to change the lock's state only when the device's location matches the lock's location, and tracks transactions on a blockchain for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional electronic locking systems are used, then ease of operation is improved, but reliability against unauthorized access deteriorates
Solution Approach 1:
The locking system is segmented into multiple independent verification layers: location verification (GPS coordinates), digital signature verification (cryptographic validation), and blockchain validation (distributed ledger confirmation). Each layer operates independently to provide comprehensive security while maintaining ease of use through automated multi-factor authentication.
Solution Approach 2:
A blockchain network acts as an intermediary between the locking system and authorized users. The blockchain validates and records access transactions immutably, serving as a trusted mediator that eliminates the need for centralized key management while simplifying the user interface.
2Reliability
If blockchain validation and location verification are implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
The system performs self-service through automated location verification, digital signature validation, and blockchain transaction processing. The lock device autonomously verifies access credentials and executes locking/unlocking operations without requiring manual intervention or complex configuration, reducing the perceived complexity for users.
Solution Approach 2:
The locking system integrates multiple functions into a single device: GPS location tracking, cryptographic signature verification, blockchain communication, and mechanical/electrical locking control. This multi-functionality consolidates what would otherwise require separate systems into one unified device, managing complexity through integration.
3Ease of operation
If contactless access control is implemented, then ease of operation is improved, but susceptibility to unauthorized access increases
Solution Approach 1:
The system performs preliminary verification of location and digital signature before granting access. By validating credentials in advance through blockchain verification, the system ensures that only authorized users can initiate locking/unlocking operations, preventing unauthorized access while maintaining contactless convenience.
Solution Approach 2:
The blockchain network provides real-time feedback on the validity of digital signatures and access requests. The system continuously monitors and validates access credentials, providing immediate confirmation or rejection of access attempts, thereby preventing unauthorized operations while maintaining ease of legitimate access.

AI summary
Blockchain-controlled and location-validated locking systems and methods are described. A method includes maintaining state information for a lock, where the first state of the lock corresponds to an open state and the second to a locked state. The method further includes receiving a current location of a device associated with a person, authorized to change a state of the lock, attempting to change a state of the lock and a current location of the lock. The method further includes receiving a digital signature from the device. The method further includes automatically transmitting a control signal to the lock to change the state of the lock only when the current location of the person is determined to be the same as the current location of the lock and a valid proof of work is performed by a miner associated with a blockchain configured to manage transactions corresponding to the lock.
