Location-Based Access Control with Customizable Geographical Ranges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current keyless entry systems (KES) face issues such as unauthorized access due to easy transferability, require advanced hardware, and have fixed unlock ranges, lacking customization and security.
Innovation Solution
A system and method utilizing a server to determine user authorization based on portable device location and credentials, allowing access only within a predefined geographical region, and enabling customizable access control through a server-connected access point device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If keyless entry systems use fixed-range sensors (Bluetooth/Wi-Fi), then access can be granted automatically, but the range cannot be customized and security is reduced
Solution Approach 1:
The system dynamically adjusts the access range by receiving location data from the portable device and comparing it against a predefined geographical region stored in the server. The actual access range becomes flexible and customizable based on user authorization settings rather than being fixed by hardware limitations, resolving the contradiction between automatic access convenience and range customization capability
2Ease of operation
If keyless entry systems use fobs or keycards, then access is convenient, but they can be easily transferred to unauthorized users
Solution Approach 1:
The system replaces physical mechanical keyless entry devices (fobs, keycards) with a server-based authentication system that uses portable devices and location data. Access is controlled through electronic verification of location and authorization status in the server, eliminating the ability to transfer physical credentials while maintaining convenience through automatic access based on location verification
3Reliability
If keyless entry systems require advanced hardware (Bluetooth/Wi-Fi enabled devices), then access control is enhanced, but device complexity and cost increase
Solution Approach 1:
The system uses universally available location services (GPS, Wi-Fi positioning, cellular triangulation) that are already built into most portable devices, rather than requiring specialized Bluetooth or Wi-Fi hardware for access control. This approach maintains security through server-based verification while reducing hardware complexity and cost requirements
Data Source
AI summary
The system includes a server including one or more processors, which are communicatively coupled to an access point device and one or more portable devices. The one or more processors are configured to retrieve location data via a sensor of the one or more portable devices configured to interact with one or more identification markers and determine whether a location of the one or more portable devices is within a pre-defined geographical area. Upon determination of the location of the one or more portable devices is within the pre-defined geographical area, the one or more processors receive a callee selection from at least one portable device of the one or more portable devices. Upon receiving a callee selection associated with accepting a request for access, the one or more processors direct the access point device to provide access to a caller.
