Beacon-Based Emergency Location System with Digital Signature Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current emergency response systems lack immediate and accurate information flow, especially during catastrophic events, and are susceptible to physical tampering, which can lead to unauthorized or erroneous distribution of life-saving information.
Innovation Solution
A beacon-based system that uses user devices to detect signals from proximity beacons, verifies their authenticity through digital signatures, and communicates with an emergency information server to determine geographical locations and detect tampering, ensuring secure and accurate emergency location services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional surveillance systems are deployed to gather information about emergency situations, then information about affected persons can be obtained, but the process is time-consuming and costly
Solution Approach 1:
The system enables affected individuals to automatically provide emergency information through their own devices. The mobile application on user devices self-activates during emergencies, automatically transmitting location, identity, and status information without requiring external surveillance deployment or manual data collection processes.
Solution Approach 2:
The patent replaces physical surveillance systems with electronic beacon-based location technology. Instead of deploying cameras and surveillance equipment, the system uses digital beacons and mobile applications to automatically detect, track, and report individual locations and statuses in real-time.
2Loss of information
If conventional radio communication systems are used during emergencies, then agencies can communicate basic information, but accurate real-time location and identity verification cannot be achieved
Solution Approach 1:
The system divides the emergency response information system into distinct functional components: beacons deployed throughout the environment, mobile applications on individual devices, and a central server. This segmentation allows each component to specialize - beacons provide location signals, devices capture individual data, and the server processes verification - achieving both accuracy and real-time performance.
Solution Approach 2:
The patent introduces beacons as intermediary elements between individuals and emergency response systems. These beacons serve as fixed reference points that enable precise location determination through signal detection, acting as mediators that translate physical proximity into verifiable digital location data.
3Ease of operation
If emergency information systems are made accessible to the public, then real-time information exchange can occur, but the system becomes susceptible to physical tampering and unauthorized distribution
Solution Approach 1:
The system applies preliminary anti-action by implementing cryptographic verification mechanisms before any emergency information is transmitted or processed. Digital signatures and verification protocols are pre-configured in the system architecture, automatically validating the authenticity and integrity of data from beacons, devices, and users before acceptance, thereby preventing tampering at the source.
4Productivity
If detailed emergency information is collected and distributed immediately, then life-saving response can be accelerated, but unauthorized or erroneous information distribution risks increase
Solution Approach 1:
The patent implements feedback loops where the central server continuously verifies information from multiple sources (beacons, device data, user input) before distributing emergency alerts. The system cross-references location data from beacons with device-reported information, creating a verification feedback mechanism that ensures accuracy while maintaining rapid response capability through automated decision-making.
Data Source
AI summary
A method for secure, beacon-based emergency location is disclosed. The method includes detecting, with an app instance executing on a user device, a signal from a beacon disposed in a geographical location physically proximate to the user device, and transmitting in response to the detecting app instance verification information to the beacon. Further, the method includes receiving, with the app instance executing on the user device, beacon verification information from the beacon, the beacon verification information being based at least partially on the app instance verification information, and transmitting the beacon verification information to an emergency information server. The method also includes authenticating, with the emergency information server, the beacon verification information to verify that the user device is physically proximate to the beacon and, if the beacon verification information is authentic, determining the geographical location of the user device based on the geographical location of the beacon.
