Visit Confirmation System Using Wireless Beacons and Computation Tasks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for confirming user visits to a location, such as stores or game venues, face challenges in preventing illegitimate authentication and scalability for large groups, particularly with GPS, NFC, BLE beacons, and two-dimensional codes, as they can be tampered with or easily duplicated.
Innovation Solution
A system involving a mobile terminal device and a server that uses wireless communication to transmit service notifications, task notifications, and solution requests, where the mobile terminal executes tasks and transmits task completion notifications, allowing the server to determine the legitimacy of visit confirmations based on temporal and spatial density, using tasks like prime factorization to ensure authenticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If GPS is used to identify user position for check-in service, then the service coverage area is large and user convenience is improved, but the system becomes vulnerable to position information tampering and illegitimate bonus acquisition
Solution Approach 1:
The patent introduces wireless devices (beacons) as intermediaries between the user's mobile terminal and the server. These beacons are placed at specific locations and transmit unique identifiers that users can detect. This intermediary system replaces direct GPS position reporting with a verified location-based authentication mechanism, preventing position tampering while maintaining user convenience.
2Reliability
If NFC is used for visit detection with secure communication, then forgery prevention is improved, but the communicable range is limited to approximately 10 cm requiring precise positioning
Solution Approach 1:
The patent segments the authentication system into multiple wireless devices placed at different locations within the target area, each transmitting unique identifiers. Instead of requiring precise single-point positioning like NFC, the system allows users to detect any of these segmented signal sources within a broader area, maintaining security while improving ease of operation.
3Productivity
If BLE beacon is used for simultaneous check-ins of large groups, then scalability is improved, but the system becomes vulnerable to illegitimate applications and network sniffing attacks
Solution Approach 1:
The patent implements preliminary actions by having wireless devices continuously transmit unique identifiers before any check-in attempt, and by requiring mobile terminals to detect these identifiers and report them to the server. The server maintains a registry of valid beacon identifiers and verifies each check-in request against this registry, preventing illegitimate applications and sniffing attacks through pre-established authentication credentials.
4Ease of manufacture
If two-dimensional code is used for check-in entry point, then implementation simplicity is improved, but the code can be easily duplicated by image capture and saving
Solution Approach 1:
The patent replaces the static mechanical two-dimensional code system with a dynamic wireless communication system. Instead of using printed codes that can be photographed and duplicated, the system uses wireless devices that continuously transmit unique identifiers that must be detected and reported to the server for verification. This substitution eliminates duplication risks while maintaining implementation simplicity.
