Smart Lock Box Access Control via Digital Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Real estate lock boxes lack advanced security and communication features, making it difficult for sellers to manage access and gauge interest in properties effectively, as they often require manual key management and lack real-time access tracking.
Innovation Solution
A smart lock box system that uses a processor to verify access messages from user devices, employing digital signatures, timestamps, and distributed ledger technology for secure and authorized access, allowing multi-party authentication and providing insights into property interest through access logs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional manual key management is used for lock boxes, then simplicity and ease of operation are maintained, but security and access tracking capabilities are insufficient
Solution Approach 1:
The patent replaces the mechanical key-based locking system with an electronic/digital system. The lock box uses a processor to verify access messages with digital signatures, timestamps, and location data, substituting physical key management with cryptographic authentication and digital tracking mechanisms.
Solution Approach 2:
The patent introduces a server as an intermediary between the lock box and users. The server manages the distributed ledger, verifies access requests, and coordinates authentication, acting as a mediator that enables secure access tracking without requiring direct complex interactions between all system components.
2Loss of information
If manual key management is used, then device complexity is low, but real-time access tracking and seller communication capabilities are lost
Solution Approach 1:
The patent implements feedback mechanisms where the lock box records access information (timestamps, location data, user identity) on a distributed ledger, and the server communicates access status to sellers in real-time. This creates a closed-loop system where access information is continuously tracked and communicated back to stakeholders.
Solution Approach 2:
The lock box system performs multiple functions: it provides secure access control, tracks access events, stores data on a distributed ledger, communicates with sellers, and verifies user authentication. This multi-functionality consolidates what would otherwise require separate manual processes into a single integrated system.
3Reliability
If advanced security features like digital signatures and distributed ledger are implemented, then access security and tracking are improved, but device complexity and operational difficulty increase
Solution Approach 1:
The patent implements self-service mechanisms where users authenticate themselves through their mobile devices using pre-configured credentials. The system automatically verifies digital signatures, checks timestamps, validates location data, and records access events without requiring manual intervention from operators or complex user actions.
Solution Approach 2:
The patent performs preliminary actions by pre-configuring user credentials, setting up the distributed ledger structure, and establishing authentication protocols before actual use. This preparation work is done in advance so that during operation, the system can automatically handle security verification without requiring users to understand or manually configure these complex parameters.
Data Source
AI summary
A smart lock box system is described. One implementation of the lock box system includes a locking mechanism configured to securely hold a cover over a compartment. The lock box system includes a receiver capable of receiving signals from a user device. The lock box system also includes a processor configured to identify an access message in a received signal, a service to verify that the access message was provided by an authorized party, and cause the locking mechanism to be released in response to verifying that the access message was provided by the authorized party. The open/close events are recorded in a distributed ledger to document which user's device was used to access a given property at a given time. Furthermore, the smart lock box system utilizes a push notification service, based on user device's GPS, to inform owners when to depart/return to the property.
