Visitor Verification System Using Beacon and Visual Code Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for verifying visits by Mobile Service Providers (MSPs) to clients' residences are prone to fraud, as they lack accurate authentication and verification of MSPs' presence, time, and service provision, especially with the decline of traditional landlines and increased use of Voice over IP and mobile devices.
Innovation Solution
A visit verification system utilizing a beacon with a transmitter and a mobile computing device that employs multiple verification methods, including RF signal monitoring, visual code recognition, GPS location verification, interactive voice response, and digital signatures to authenticate MSPs and track their presence and task completion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional landline calling systems are used for MSP check-in/check-out verification, then the system is simple to operate, but the system becomes vulnerable to fraud through call impersonation and location spoofing
Solution Approach 1:
The patent combines multiple verification technologies (RF beacon tracking, visual code recognition, GPS location verification, interactive voice response, and digital signatures) into a unified verification system. This integration allows the system to cross-validate multiple data sources simultaneously, making fraud significantly more difficult while maintaining operational simplicity through automated processing.
Solution Approach 2:
The verification system is designed to work across multiple platforms and communication methods (mobile devices, landlines, beacons, visual codes) simultaneously. This multi-functional approach ensures that the system can verify MSP presence and identity through various channels, reducing vulnerability to any single method's limitations or fraud vectors.
2Measurement precision
If multiple verification methods (RF signals, visual codes, GPS) are implemented, then fraud detection accuracy improves, but the device complexity increases
Solution Approach 1:
The system pre-establishes verification parameters and thresholds before MSP arrival. Beacons are pre-configured with identification codes, visual codes are pre-generated for specific locations and time windows, and GPS coordinates are pre-mapped. This preliminary setup automates the verification process during actual check-in, reducing real-time complexity while maintaining high precision.
Solution Approach 2:
The patent introduces intermediate verification elements such as beacons with visual codes and automated voice response systems that mediate between the MSP and the central verification server. These intermediaries simplify the user interface and automate complex verification logic, allowing multiple verification methods to work together without overwhelming the end user.
3Reliability
If automated authentication systems are deployed, then fraud prevention improves, but the ease of operation for MSPs decreases
Solution Approach 1:
The verification system is designed to be self-serve for MSPs. Upon arrival, MSPs automatically detect nearby beacons, scan visual codes, and have their GPS location verified without manual intervention. The system autonomously cross-checks these data points and completes authentication, minimizing the steps MSPs must manually perform while maintaining high security standards.
Solution Approach 2:
The patent replaces manual verification processes (phone calls to base, physical sign-in sheets) with automated electronic verification. Mobile devices automatically communicate with beacons via RF signals, visual codes are scanned by cameras, and GPS coordinates are automatically transmitted and verified. This substitution of mechanical/manual processes with automated electronic systems maintains simplicity for users while dramatically improving authentication reliability.

Function Achieved in This Case
The system provides accurate and minimally intrusive verification of MSPs' visits, reducing fraud by ensuring proper authentication and recording of service provision, even in areas with limited internet or cellular connectivity, and maintaining client privacy.

AI summary
A visitor verification system 1000 is disclosed and described that can automatically authenticate a Mobile Service Provider (MSP) 3 arriving to provide assistance to a patient, or client 5 at their residence 7 while being off-line with the agency server. It also verifies the time and location a MSP session begins, periodically verifies that the MSP 3 is within the client's residence 7, logs the MSP out of the system and reports on the session. The visitor verification system employs at least one visual code located at the residence 7 that is scanned by a mobile computing device (MCD) 100. Information in the visual code is decoded and reconciled with locations determined by executable code (the App) running on the MCD 100. Once the location is verified by the App/MCD 100, the MSP 3 is authenticated. The system includes at least one beacon that transmits a signal that the MSP receives on the MCD 100. The received signal can be used to determine the MSP's distance from the beacon or to monitor the MSP's locations throughout the session. Information acquired during the session may be uploaded immediately, or at a later time when network connectivity is available, through a network 13 to a server 400 to be used by the system.
